Replacing Bearings For Carrier, Front FA

Information 

If a suspension sub-frame 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).

8. Press in suspension sub-frame bearing. To avoid damaging the bearing, the maximum → Pressure: 10 kN+/-5 Sekunde  must not be exceeded at the stop (10 KN = 350 bar). This conversion applies only to the hydraulic cylinder VAS 6178. The conversion depends on the diameter of the cylinder in question.
