Differential Service
Protect the gears that deliver power through an axle.

Service overview
WHAT TO KNOW
The differential allows the driven wheels to turn at different speeds in a corner. Its lubricant protects gears and bearings. Fluid type and any limited-slip additive requirements depend on the axle, so service starts with identifying the correct specification.
When to have it checked
- Whining or rumbling from an axle
- Fluid around the differential housing
- Differential fluid service is due
Planning your service
Use the manufacturer’s interval for your axle and driving conditions. New noises call for diagnosis rather than a fluid change alone.
Step by step
WHAT TO EXPECT.
A typical differential service visit follows these steps. The exact work depends on your vehicle and inspection findings; repairs are discussed before proceeding.
Inspect the assembly
Check the housing, seals and any reported axle noise.
Assess the lubricant
Review fluid condition, level where accessible and service requirements.
Service when due
Replace lubricant to the axle specification if required and approved.
Check for leaks
Verify the finished service and discuss any further wear concerns.
