What's involved
What this repair actually is.
A technician road-tests your vehicle to reproduce the noise or vibration, then inspects the CV axles, driveshaft, u-joints, differential, and hubs on a lift. Drivetrain noises travel through the body of the car, so careful testing is needed to tell a bad axle from a bad bearing or differential before any parts are replaced.
Symptoms
How you can tell.
- Clicking or popping when turning
- Clunk when shifting into Drive or Reverse
- Humming or growling that changes with speed
- Vibration that gets worse as you accelerate
- Whining noise from under the rear of the car
- Shudder or binding feeling in tight turns
If you delay
Drivetrain noises almost always point to a worn part that will keep wearing until it fails, sometimes leaving the vehicle unable to move.
