Warning Signs of a Failing Rear Axle Shaft
- A clicking or popping noise coming from the rear wheel area, especially when turning.
- Vibrations in the vehicle, particularly at higher speeds.
- Leaking gear oil near the rear wheel.
- Difficulty accelerating or a feeling of "slipping" in the rear.
- Uneven tire wear on the rear tires.
Testing the Rear Axle Shaft
If you suspect a problem with your rear axle shaft, here's how to check it:
- Safely lift the vehicle and support it with jack stands.
- Visually inspect the axle shaft for any signs of damage, such as cracks, bends, or excessive wear.
- Check for excessive play or movement in the axle shaft by trying to wiggle it. A small amount of play is normal, but excessive movement indicates a problem.
- Rotate the wheel and listen for any unusual noises coming from the axle shaft area.
- Inspect the axle shaft seal for leaks.
If you find any of these issues, the rear axle shaft may need to be replaced. It's important to rule out other potential problems, such as worn wheel bearings or a damaged differential, before replacing the axle shaft.
Common Causes of Rear Axle Shaft Failure
- Normal wear and tear over time.
- Impact damage from accidents or hitting potholes.
- Lack of lubrication.
- Corrosion due to exposure to water and salt.
- Excessive stress from towing or off-road driving.
