Common Axle Problems in Heavy-Duty Trucks and How to Fix Them

We at Kingfleet have been helping heavy-duty truck owners solve their most pressing problems. While we've tackled a multitude of issues, a particular component frequently captures our attention — the axle. An integral component of your truck's drivetrain, axles bear the weight of the vehicle, cargo, passengers, and even absorb the brunt of road conditions. When axle problems arise, they're not something to turn a blind eye to. We've compiled a list of common axle problems in trucks and how to fix them, ensuring your truck operates at its peak performance.

What is an Axle, and Why is it Important?

Before diving headlong into the most common axle problems, getting acquainted with the axle's role is imperative. The axle is nestled beneath the vehicle and transfers power and torque from the engine to the wheels. This ensures movement. If you've ever wondered what keeps your truck moving forward or in reverse, tip your hat to the axles. Heavy-duty truck axles are particularly robust, given the sheer weight they must support.

1. Worn Out Bearings

Signs: A high-pitched noise emanating from your truck when you drive, especially during turns, can often be traced back to worn-out bearings.

How to Fix: Bearings, although sturdy, aren’t immortal. Over time, they wear out and need replacing. If you hear any suspicious sounds, it's time to bring your truck to a professional repair shop like Kingfleet. We'll replace those bearings, ensuring a smoother, quieter ride.

2. Damaged CV Joints

Signs: A clunking noise during acceleration or deceleration can clearly indicate that the CV (Constant Velocity) joints are compromised.

How to Fix: If you suspect CV joint damage, it's paramount to replace them promptly. These joints are crucial for transferring the torque from the transmission to the drive wheels at a constant speed while accommodating the up-and-down motion of the suspension. At Kingfleet, we'll have these joints inspected and replaced if necessary.

3. Axle Shaft Wear and Tear

Signs: If you spot greasy spots on the inner edges of tires or underneath the drive axle, it’s a tell-tale sign of axle shaft wear.

How to Fix: The axle shaft is the component that you'd colloquially call the "rod" of the axle system. As it's responsible for taking much of the wear, particularly in heavy-duty trucks, it's susceptible to wear and tear. Routine inspections and prompt replacements are the keys to addressing this issue.

4. Differential Issues

Signs: A banging or clunking noise, especially when making tight turns, indicates potential differential problems. Remember, the differential allows your truck's wheels to rotate at different speeds, which is essential during turns.

How to Fix: Regularly changing the differential oil and ensuring no contamination is the first step. If problems persist, the differential might need a more in-depth examination or, in some cases, replacement.

5. Axle Seal Leaks

Signs: If you notice a puddle of fluid under the differential or gearbox area, there's a good chance you're dealing with an axle seal leak.

How to Fix: Seal leaks often result from wear and tear or damage. Replacing them at a professional shop will prevent fluid leaks and potentially further damage.

Maintaining Your Truck's Axles

It's worth noting that while the axles in heavy-duty trucks are built to last, they're not immune to problems. Regular maintenance and inspections can save you a great deal of time, money, and stress in the long run.
