Frequently Asked Questions
we can repair and maintain various types of heavy-duty trucks, such as semi-trucks, dump trucks, cement mixers, garbage trucks, flatbed trucks, and more. Services might include things like engine diagnostics, brake and transmission repair, suspension work, and general maintenance. If you have a specific truck type or issue in mind, I can go into more detail.
Your truck could pull to one side when braking due to uneven brake pad wear, where one side is more worn than the other. Another possibility is a stuck caliper, which would cause one side to brake more forcefully. There could also be an issue with your brake fluid, like air in the lines or a leak on one side, reducing braking power. Wheel alignment problems can also cause this, as well as uneven tire wear or incorrect tire pressure. A mechanic can inspect it and figure out the exact issue.
If your truck starts to overheat, the first thing you should do is pull over to a safe location and turn off the engine. Let the engine cool down before opening the hood, as the coolant could be boiling and create steam. Once it’s cooled, you can check the coolant level and add more if necessary. If you don’t have coolant, you can use water temporarily. Avoid driving long distances if the truck continues to overheat, as this could damage the engine. It’s best to have a mechanic check for issues like a coolant leak, a faulty thermostat, or a broken radiator.
Yes, we carry OEM parts for most major models of heavy trucks. If we do not have the part you are searching for, our team will help you locate quality parts replacements for your vehicle.
Tires on a heavy truck should generally be rotated every 6,000 to 8,000 miles, but it can depend on the type of truck and how it’s used. Regular rotations help ensure even tire wear and extend the lifespan of the tires. If your truck carries heavy loads or is used in rough conditions, you might need to rotate them more often. Always check the truck’s manual or consult a mechanic for the best schedule based on your specific truck and driving habits.
