Axles are a vital component of your heavy-duty diesel truck and need to be in top shape for optimum performance. Here we discuss everything that you need to know about axles, including how to spot when yours need some TLC.
Bearing and Race Maintenance
There are two distinct yet equally crucial parts of your axles that both require routine maintenance.
Bearing Maintenance
Your heavy-duty diesel truck’s bearings require grease at all times to facilitate the rotational movement of the wheels. Over time, the grease becomes less effective or contaminated by water, dirt, or any foreign substance, which can cause an increased amount of friction.
This could lead to premature wear and damage to the axle, resulting in expensive repairs and downtime. To avoid this, bearings should be freshly lubricated every 12 months or 12,000 miles.
Race Maintenance
Although the races on your axle are typically constructed of high-strength materials like hardened steel, damage can still occur to them.
Your races will need to be completely changed if they are:
- Warped
- Rough
- Rusted
- Have heat marks
If your heavy-duty diesel truck is up for bearing or race maintenance, contact Blue Ridge Truck Service at 726 Cedar Lane, Cana, VA 24317, and book your appointment today.
Signs of Failing Bearings
It is essential that you are aware of any indicators that your bearings are failing in order to schedule essential maintenance. Signs include:
- If the wheel shakes when placed in the air (play in the wheel)
- Overheating hub
- A “metal-on-metal” grinding sound
- Visible grease leakage
(Either dripping when stationary or sprayed all over the rim after a long drive) - Uneven tire wear
- A noticeable decrease in handling and control
If you notice any of these symptoms, contact Blue Ridge Truck Service at 726 Cedar Lane, Cana, VA 24317, and book your appointment immediately.
Types of Axles
There are two main types of axles in heavy-duty diesel trucks.
Powered Axles
These are found in wheels that receive power from a differential.
Common issues:
- Axle shaft failure
- Warped axle shaft
- Seized axle shaft
Non-Powered Axles (AKA Spindles)
Spindles do not receive power from a differential and can be found at the front of 2WD vehicles and trailers.
Common issues:
- Bearing failure can damage the spindle through excess friction and heat
(In severe cases this can cause the bearings to become welded to the spindle)
To fix any of these issues, contact Blue Ridge Truck Service at 726 Cedar Lane, Cana, VA 24317, and book your appointment today.
