Differential
The differential lets your wheels spin at different speeds when you turn, which keeps your ride smooth and your tires from dragging. Our technicians inspect, repair, or replace worn gears, bearings, and seals, and refill the differential fluid. If you hear whining, clunking, or feel a vibration while driving, we'll get it sorted out.

Frequently asked questions
How do I know if my differential is going bad?
Common signs include a whining or howling noise that changes with speed, a clunk when accelerating or turning, vibration, or fluid leaking under the rear of the vehicle. If you notice any of these, it's best to have it checked soon.
Can I keep driving with a noisy differential?
It's not recommended. A noisy differential usually means worn gears or bearings, and continuing to drive can lead to complete failure, which is far more expensive to fix and could leave you stranded.
How often should differential fluid be changed?
Most manufacturers recommend changing it every 30,000 to 60,000 miles, but it can vary by vehicle and driving conditions. Towing or off-roading may require more frequent changes.
