Replacing Bearings For Carrier

Information 

If a suspension subframe bearing is replaced, the other bearings must also be checked for cracks or other signs of damage.

1. Loosen the anti-roll bar from the connecting link on both sides. (Do not loosen the anti-roll bar for the rear front-axle bearings!)
2. Move the gear support under the engine transverse bar and lift it slightly using a suitable base (e.g. hard rubber support). (The gear support is not needed for the rear front-axle bearings).

3. Engage the spindle at the eyelet on the engine transverse bar at the side where you want to replace the bearing. Guide the spindle through the lower trailing arm and tighten the spindle slightly so that the spindle is slightly tensioned.
