4 Important Reasons to Never Skip Semi Truck Oil Changes

When you’re hauling thousands of pounds down the highway, there’s no room for steering problems. Semi truck steering issues can sneak up on even the most experienced drivers, and if ignored, they can lead to dangerous situations and costly repairs. Knowing what to look for and how to handle it can keep you safe and your truck road-ready. When you need semi truck repair in Phoenix or the surrounding towns, S & K Transmission & Diesel Repair offers unbeatable service. Loose Steering or Excessive Play If you notice a delay between turning the wheel and the truck responding, you may have worn tie rods or a failing steering gearbox. These issues reduce your control, especially at higher speeds. A quick inspection from a qualified mechanic can pinpoint the problem, and parts like bushings, linkages, or gears may need replacing. Hard Steering If you feel like you're wrestling with the wheel, low power steering fluid could be to blame. Other potential issues include a faulty power steering pump or problems with the steering column. Regular fluid checks and top-offs can prevent major headaches. If the issue persists, it’s time to visit a heavy-duty repair shop for a full steering system inspection. Vibration or Shaking While Turning This could indicate uneven tire wear, misalignment, or suspension issues. Vibrations can also come from damaged steering components. Catching these early can prevent further wear on your tires and avoid strain on other systems. Pulling to One Side If your semi constantly drifts to one side, don’t blame the road; it’s likely a sign of misalignment or uneven tire pressure. Regular alignments and keeping tires properly inflated are easy preventative measures. Stay Proactive with Maintenance To prevent steering issues, stick to a consistent maintenance schedule. Routine inspections of the steering system, fluid levels, suspension, and alignment can help you spot problems before they escalate. When in doubt, get your truck checked by a professional technician who specializes in commercial vehicles.

Phoenix is a desert dream for RV lovers with wide-open roads, iconic red-rock landscapes, and year-round sunshine. But that same blazing sun and dry air can be rough on your rig. Whether you're a full-time RVer or a weekend adventurer, keeping up with maintenance can help you avoid costly breakdowns and stay road-ready in the Valley of the Sun. When you need RV maintenance or repair in Phoenix or the surrounding towns, S&K Transmission & Diesel Repair offers unbeatable service. Keep an Eye on Your Roof The Arizona sun is relentless, and your RV's roof takes the brunt of it. UV rays can dry out sealants, leading to cracks and leaks. Make a habit of inspecting the roof regularly, especially around vents, skylights, and AC units. Re-seal any trouble spots before they become full-blown leaks. A clean roof also helps reflect heat, which is a big plus in 100+ degree temperatures. Don’t Neglect the Tires Tires are your RV’s foundation; in Phoenix’s extreme heat, they can wear faster than you think. Check tire pressure monthly and always before a trip. Look for signs of cracking or bulging, especially if your RV has been sitting for a while. Don’t forget to check the spare, too! AC Is Everything Let’s be honest, air conditioning isn’t optional in Phoenix. Your RV’s AC system works overtime here, so clean or replace filters regularly and keep the coils free of debris. Consider a professional inspection before the summer heat kicks in to make sure everything’s running smoothly. Flush and Sanitize the Water System If your RV’s been sitting idle, your water system can harbor bacteria or develop a funky smell. Sanitize the fresh water tank at least once a season, and flush it out regularly to keep things fresh. In the Phoenix heat, stagnant water can quickly become a problem. Battery Maintenance Matters High desert temperatures can evaporate battery fluid quickly. Check fluid levels in lead-acid batteries and ensure terminals are clean and corrosion-free. If you use solar panels, make sure they're functioning efficiently. RV Repair in Phoenix If your RV suffers a mechanical failure, S&K Transmission & Diesel Repair is here to help.

When your semi truck refuses to start, you lose time, money, and productivity. A no-start issue can stem from various sources, from electrical faults to fuel system failures. Understanding the potential causes can help you troubleshoot the problem and get back on the road faster. When you need semi truck repair in Phoenix or the surrounding towns, S & K Transmission & Diesel Repair offers unbeatable service. Starter or Ignition Issues If your battery is in good shape, but your truck still won’t start, the problem could lie in the starter or ignition switch. A failing starter motor might produce a clicking noise but fail to engage the engine. Similarly, a faulty ignition switch may prevent power from reaching essential components. Fuel System Failures Diesel engines rely on a steady fuel supply, and any disruption can leave you stranded. Clogged fuel filters, air in the fuel lines, or a failing fuel pump can prevent your engine from getting the diesel it needs to start and run. If your engine cranks but doesn’t fire up, fuel delivery could be the issue. Sensor or ECM Malfunctions Modern semi trucks use an Engine Control Module (ECM) to regulate critical functions. If a key sensor, such as the crankshaft position sensor, malfunctions, the ECM may not allow the truck to start. A diagnostic scan can help pinpoint any trouble codes related to electronic issues. Cold Weather Complications In freezing temperatures, fuel gelling or weak glow plugs can make starting a diesel engine challenging. If your truck struggles to start in the cold, using anti-gel additives and ensuring your glow plugs are functioning can help. Getting Back on the Road If your semi truck refuses to start, checking the battery, starter, fuel system, and key sensors can help identify the problem. When in doubt, a professional mechanic with diagnostic tools can get you back on the road quickly.

A semi truck transmission rebuild is a comprehensive process that revitalizes one of your vehicle’s most critical components. Given the heavy loads and long hours these trucks endure, transmissions can suffer from wear and tear over time. A rebuild, when performed properly, restores functionality and enhances performance and reliability on the road. For semi truck transmission repair in Phoenix or the surrounding towns, S & K Transmission & Diesel Repair offers unbeatable service. Initial Assessment and Removal The process begins with a thorough diagnostic evaluation. Technicians assess the transmission to determine the extent of the damage and to decide whether a rebuild is feasible. Once the decision is made, the transmission is carefully removed from the semi-truck. This step is delicate work, requiring precision and the right equipment to prevent further damage to surrounding systems. Disassembly and Inspection After removal, the transmission is disassembled piece by piece. Every component—from gears and clutches to bearings and seals—is inspected for wear, damage, or corrosion. Technicians pay close attention to parts that typically bear the brunt of heavy usage, as these are the most likely candidates for replacement. Detailed inspection at this stage is critical; it ensures that every potential issue is identified and addressed during the rebuild. Cleaning and Replacement Once disassembled, all components are meticulously cleaned to remove grime, metal shavings, and old lubricant. Cleaning aids in the inspection process and ensures that new parts can operate without interference from debris. Any worn or damaged parts are then replaced with new or refurbished components that meet the manufacturer’s specifications. Reassembly and Testing With all components cleaned and replaced as needed, the transmission is reassembled. Technicians follow precise guidelines to ensure each part fits and functions perfectly. After reassembly, the transmission is rigorously tested to verify that it meets performance standards. This testing phase is needed to catch any potential issues before the transmission is reinstalled in the truck. Final Installation Once the rebuilt transmission passes all tests, it is reinstalled in the truck. Technicians make sure that all connections are secure and that the system is properly integrated with the vehicle’s engine and control systems. A final road test may follow to ensure that the truck runs smoothly and efficiently. Truck Transmission Rebuild & Overhaul Services in Phoenix In some circumstances, the right repair for a gearbox is to fully overhaul it. At S&K Transmission & Diesel Repair, we offer expert automatic and manual transmission rebuilding for all makes and models of commercial vehicles. Our thorough transmission overhaul process ensures the unit shifts like new when it leaves our shop.

Semi trucks rely on powerful braking systems to handle their massive size and weight, especially when carrying heavy loads. These systems aren’t the same as those on passenger vehicles, and proper maintenance is needed to keep them operating safely. Below is a breakdown of the different types of brakes semi trucks use and tips for keeping them in top condition. When your truck needs brake maintenance in Phoenix or the surrounding towns, S & K Transmission & Diesel Repair offers unbeatable service. Air Brakes The most common braking system on semi trucks is the air brake system, which includes service brakes, parking brakes, and emergency brakes. Air brakes use compressed air to apply pressure, engaging the brake pads or shoes to slow the truck. They’re highly effective and designed to handle the demands of heavy-duty vehicles. To maintain air brakes, regularly inspect the air lines, compressor, and reservoirs for leaks or damage. Ensure air pressure levels are within the recommended range, as low pressure can compromise braking power. Disc Brakes Many modern semi trucks are equipped with air disc brakes, which offer better stopping power and improved heat dissipation compared to traditional drum brakes. These brakes are less prone to fading during heavy use, making them a safer option for steep descents or long hauls. Maintenance for air disc brakes involves inspecting the rotors and pads for wear and replacing them as needed. Keep an eye on the calipers to ensure they’re functioning smoothly. Drum Brakes While disc brakes are replacing drum brakes in many cases, they’re still widely used in semi trucks. The brake shoes are pressed against the inside of the drum to create friction. Regular maintenance includes checking for worn shoes, warped drums, and ensuring proper lubrication of components. Maintenance Tips for All Brake Types Perform regular inspections of brake components, including pads, rotors, drums, and air lines. Monitor brake performance for signs of wear, such as squealing, grinding, or reduced stopping power. Replace worn parts promptly to avoid further damage to the system. Keep brake systems clean and free from debris, especially after driving in muddy or snowy conditions. Brake Service in Phoenix Big rigs cover a lot of ground day after day, which is why routine brake maintenance is so critical to their long-lasting performance. S&K Transmission & Diesel Repair offers everything you need at our Phoenix semi truck shop to keep yourself rolling down the road. Don’t hesitate to give us a call at  623-244-8887  when it’s time for preventative semi truck maintenance.

While winters in Phoenix are relatively mild compared to other parts of the country, semi trucks are not immune to the unique challenges that come with the season. Cooler temperatures and occasional weather shifts can still cause issues for your truck, potentially delaying schedules and increasing repair costs. Below are some common winter problems your semi might face and how to address them. When you need semi truck repair in Phoenix or the surrounding towns, S & K Transmission & Diesel Repair offers unbeatable service. Battery Troubles Even in Phoenix, cooler temperatures can strain your truck’s battery. Cold weather reduces a battery’s capacity, making it harder for your engine to start. If your truck struggles to start or the battery is older than three years, it might be time for a replacement or regular inspections to ensure reliability. Tire Pressure Fluctuations Cooler desert nights can cause tire pressure to drop. Underinflated tires wear unevenly and reduce fuel efficiency, both of which can lead to costly downtime. Check your tire pressure regularly and ensure they meet the manufacturer’s recommended levels. Coolant System Issues Phoenix winters might not reach freezing, but maintaining your coolant system is still vital. Low temperatures can affect the efficiency of your coolant and antifreeze mix, potentially leading to engine overheating. Ensure your coolant levels are adequate and the system is free of leaks or blockages. Fuel System Problems Semi trucks running on diesel are vulnerable to fuel gelling in colder conditions. While rare in Phoenix, early morning temperatures could still cause diesel to thicken slightly. Using a winter-grade diesel or fuel additive can prevent this issue. Visibility Challenges Morning frost or rare rain can impair visibility. Make sure your windshield wipers are in top condition, and keep washer fluid topped off with a formula designed for cooler temperatures.

Winterizing an RV in Phoenix may not seem like a priority due to the region’s mild winters, but neglecting basic maintenance can lead to costly repairs down the road. Proper winterization protects your investment, keeps your RV in top condition, and ensures it’s ready for future adventures. Here’s how to prepare your RV for the cooler months in the Valley of the Sun. When you need RV maintenance or repair in Phoenix or the surrounding towns, S & K Transmission & Diesel Repair offers unbeatable service. Drain and Protect the Water System Even in Phoenix, occasional freezing temperatures can damage your RV's plumbing. Drain the fresh water, gray water, and black water tanks completely. Flush the system and add RV-specific antifreeze to prevent cracked pipes and fittings. Clean and Inspect the Exterior Wash your RV thoroughly to remove dirt, grime, and bug splatter that can damage the finish. Inspect the roof, seals, and seams for cracks or leaks. Apply a protective sealant as needed, and consider using an RV cover to shield your vehicle from UV rays and winter dust storms. Prepare the Interior Remove perishables and any items that could attract pests. Clean the interior thoroughly and inspect for signs of rodents or insects. Use moisture absorbers to prevent condensation, which can lead to mold and mildew. Maintain the Battery Disconnect the battery or use a trickle charger to keep it from discharging over time. Clean the terminals and store the battery in a cool, dry place if you won’t be using your RV for an extended period. Check the Tires Inflate your tires to the manufacturer’s recommended pressure, as cooler weather can cause them to deflate. Inspect for wear or damage, and consider using tire covers to protect against UV exposure. Service the Engine and Generator Top off all fluids, including oil and coolant, and run the generator periodically to keep it in working order. Add a fuel stabilizer to prevent gas from degrading during storage. RV Repair in Phoenix If your RV suffers a mechanical failure, S&K Transmission & Diesel Repair is here to help.

If you notice your semi truck dripping oil, it’s best to address the issue quickly to avoid costly repairs and downtime. Oil leaks can stem from a variety of causes, some minor and others more serious. We discuss the top reasons your semi truck might be dripping oil below. When you need semi truck repair in Phoenix or the surrounding towns, S & K Transmission & Diesel Repair offers unbeatable service. Worn or Damaged Gaskets Gaskets are critical in sealing parts of your engine to prevent oil leaks. However, due to high temperatures and constant pressure, these gaskets can wear out or become damaged over time. Valve cover gaskets, oil pan gaskets, and head gaskets are common culprits. If the gasket has worn down, the oil may start seeping through the seal and lead to noticeable drips under your truck. Regular maintenance can help catch gasket issues early before they result in significant leaks. Loose or Damaged Oil Pan The oil pan sits at the bottom of your engine, holding the oil that keeps the engine lubricated. If the oil pan becomes loose, cracked, or dented due to road debris or rough driving conditions, oil can start leaking from the area. A loose drain plug or a failing oil pan seal can also contribute to the leak. Inspecting the oil pan during routine maintenance is important to avoid these kinds of problems. Faulty Oil Filter A clogged or improperly installed oil filter can cause oil to leak. When an oil filter isn't properly sealed, or if the filter is worn out, it may allow oil to drip from the filter housing. This is often an easy fix, but if ignored, it can lead to reduced oil levels and engine performance issues over time. Crankshaft or Camshaft Seals The crankshaft and camshaft seals are designed to keep oil inside the engine where it belongs. However, these seals can degrade over time due to heat and engine wear, causing oil to leak from the front or rear of the engine. When these seals fail, you’ll likely notice oil dripping at the front or rear of the truck, which requires immediate attention to prevent further engine damage. Overfilled Oil Reservoir Overfilling your truck’s oil reservoir can lead to excess pressure in the system, causing oil to leak from otherwise good-condition seals and gaskets. Always ensure that the oil level is within the manufacturer’s recommended range to avoid unnecessary leaks caused by too much oil in the system.

Tire damage is a serious concern for semi trucks, as it can lead to costly delays and safety hazards. Understanding the most common causes can help truck drivers and fleet managers prevent unexpected blowouts and extend tire life. When your semi truck needs tire repairs in Phoenix or the surrounding towns, S & K Transmission & Diesel Repair offers unbeatable service. Underinflation or Overinflation Incorrect tire pressure is one of the leading causes of tire damage. Underinflated tires flex more, generating excess heat and leading to blowouts, while overinflated tires are more prone to punctures and uneven wear. Regularly check your truck’s tire pressure to prevent these issues. Overloading Semi trucks are designed to carry heavy loads, but overloading puts additional strain on tires. The extra weight can cause premature wear and sidewall damage, and increase the risk of tire failure, especially on long hauls. It’s important to properly distribute the truck’s load and adhere to weight limits. Road Hazards Debris, potholes, and uneven road surfaces can wreak havoc on truck tires. Hitting potholes at high speeds can lead to sidewall damage or blowouts if you run over sharp objects. Vigilance and avoiding damaged roads when possible can help reduce these risks. Improper Alignment Misaligned wheels cause uneven tire wear, leading to premature failure. Semi trucks are especially vulnerable to alignment issues due to their size and the demanding conditions they operate under. Regular alignment checks help ensure tires wear evenly and last longer. Heat Build-Up Long-distance driving generates significant heat in semi truck tires, especially in warmer climates or under heavy loads. Excessive heat can cause tread separation and blowouts. Proper tire pressure, load management, and allowing tires to cool when necessary can prevent heat-related damage.
