Wheel Bearing In Curb Weight, Lifting Vehicles With Coil Spring
Special tools and workshop equipment required
- Engine and Gearbox Jack :VAS6931
- Tensioning Strap :T10038
- Engine/Gearbox Jack Adapter - Wheel Hub Support :T10149
All bolts at suspension parts with bonded rubber bushings must always be tightened in curb weight position (unloaded condition).
Bonded rubber bushings can only be turned to a limited extent.
Parts with bonded rubber bushings must therefore be brought into a position that corresponds to the position in driving mode before being tightened (curb weight position).
Otherwise, the bonded rubber bushing will be stressed resulting in a shortened service life.
By raising appropriate suspension using :VAS6931 and :T10149 , this position can be simulated on the hoist.
-- Before starting work, determine the measurement -a- , for example with tape measure, from center of wheel to lower edge of wheelhouse.
Measurement must be performed in curb weight position (unloaded condition).
-- Note the measures values. It will be required for tightening bolts/nuts.
Before appropriate suspension is raised, vehicle must be strapped to lift arms of hoist using :T10038 .
The vehicle could fall off the hoist if it is not secured.
-- Turn the wheel hub until one of the holes for the wheel bolts is on top.
-- Install :T10149 with wheel bolt on wheel hub.
-- Lift the wheel bearing housing using the :VAS6931 until dimension -a- is reached.
Tightening of the respective bolts/nuts must only occur if dimension -a- , measured before installation between wheel hub center and lower edge of wheel house, has been attained.
- Do not lift or lower the vehicle when the :VAS6931 is below the vehicle.
- Do not leave the :VAS6931 under the vehicle any longer than necessary.
-- Tighten the bolts and nuts.
-- Lower the wheel bearing housing.
-- Move the engine/gearbox jack away from under vehicle.
-- Remove the :T10149
