FAQ
Differential - Common Questions
How often should I change differential fluid?
Most manufacturers recommend changing differential fluid every 30,000 to 60,000 miles. Vehicles used for towing, hauling, or off-road driving should follow the severe-service interval, which is roughly half that distance.
What is the difference between open and limited-slip differentials?
An open differential lets the wheels spin at different speeds but sends power to the wheel with the least traction, so one slipping wheel can stall progress. A limited-slip differential (LSD) redirects torque to the wheel with more grip to maintain traction.
How much does differential repair cost?
Differential repair ranges from about $200 for a fluid change to $1,500 to $4,000 for a full rear-axle rebuild or replacement. Front differentials and limited-slip units typically cost more due to added complexity.
