Transfer Case buying guide
Why replace this part?
The transfer case on four-wheel-drive and all-wheel-drive vehicles distributes torque between the front and rear axles. Internal chain and gear wear causes vibration, noisy engagement, and in severe cases seizes the four-wheel-drive system.
Signs you need a replacement
- Difficulty engaging four-wheel-drive
- grinding noise in 4WD mode
- vibration at certain speeds in 4WD
- oil leak from the transfer case
- 4WD system warning light
When to replace
Change transfer case fluid every 30,000โ50,000 miles. Rebuild or replace when noise or engagement problems develop.
