Differential & Transfer Case Rebuilds & Repairs

Maintain your drivetrain all the way to the axle

Your differential or transfer case needs to operate efficiently to transfer the torque coming out of the transmission to the wheels. Differential faults or transfer case problems will see your vehicle operate at reduced power or not at all.

The differential sits on the drive axle and regulates the power to the two wheels on that axle. On a standard rear-wheel drive car, for instance, the outer wheel has to travel a slightly longer distance when you turn and therefore needs more power.

A four-wheel drive vehicle also needs a transfer case in addition to differentials on both axles. A transfer case does a similar job as a differential. It splits the torque between the front and rear axles. Some transfer cases operate part-time to allow more economic two-wheel driving when four-wheel drive isn’t needed, while others are engaged full-time. Some of the latest transfer cases can automatically shift from two-wheel to four-wheel drive, depending on driving conditions. Transfer cases can be gear driven (mostly for larger or hard-working vehicles) or chain driven (popular for lighter and recreational vehicles).

The most obvious early signs of trouble with a differential or transfer case are knocking or clunking sounds, rumbles or oil leaks.

How we rebuild & repair your differential or transfer case

Diagnosing what’s wrong always comes first. Sometimes this can be done without any major dismantling. When we do have to take apart the differential or transfer case, we strip it right down and inspect each part for damage. Any unserviceable components are replaced with new or reconditioned parts. Those that pass our tests are cleaned and returned to the assembly.

Depending on the extent of the fault in your differential or transfer case, it may be more cost-effective for you to exchange the entire unit rather than repair or rebuild your original. Our technicians will advise you if you need an exchange differential or transfer case once we’ve determined how serious the problem is.

Whether we repair or rebuild, we always test your differential or transfer case to ensure it works perfectly.
