How do I know if my GMC drivetrain is damaged?

Noises toward the back of your GMC Sierra 2500 HD, leaking fluid, trouble turning — these could all be signs of drivetrain damage you want to address. Take action before something more severe happens.

When should I come in for GMC Sierra 2500 HD differential service?

Double check your owner’s manual and talk with a technician. Differential service frequency varies from car to car.

Why is the malfunction indicator light (MIL) on in my Sierra 2500 HD?

Can you clear the Sierra 2500 HD check engine light on your own?

While it’s sometimes possible to clear a malfunction warning light at home, it’s never recommended.
