Step-by-Step Hanger Bearing Replacement Guide

1. Safety First

Park the vehicle on a level surface, engage the parking brake, and let the engine cool down. Safety should always be your top priority.

2. Lift the Vehicle

Using a jack and jack stands, safely lift the vehicle to provide ample working space under the car. Ensure the vehicle is stable and secure before proceeding.

3. Locate the Hanger Bearing

The hanger bearing is typically located on the driveshaft, between the transmission and the rear differential. It may be covered by a protective boot or shield.

4. Remove the Old Bearing

Using a wrench or socket, loosen the bolts holding the hanger bearing in place. Remove the bolts and carefully pull the old bearing off the driveshaft. In some cases, you may need to use a pry bar to gently pry the bearing loose.

5. Clean the Driveshaft

Clean the driveshaft where the hanger bearing was located to remove any dirt or debris. This will ensure a proper fit for the new bearing.

6. Lubricate the New Bearing

Apply a generous amount of lubricant to the inner and outer surfaces of the new hanger bearing. This will help prevent premature wear and extend the bearing's lifespan.

7. Install the New Bearing

Slide the new hanger bearing onto the driveshaft and align it properly. Tighten the bolts securely, ensuring the bearing is firmly in place.

8. Reinstall the Boot or Shield

If applicable, reinstall the protective boot or shield over the hanger bearing. This will protect the bearing from dirt and moisture.

9. Lower the Vehicle

Carefully lower the vehicle back to the ground, remove the jack stands, and tighten the lug nuts.
