Wheel Bearing In Curb Weight, Lifting Vehicles With Coil Spring, Front Axle
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 have a limited range of motion.
Axle components with bonded rubber bushings must be brought into the position they will be in during driving before tightening (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, take 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 measured value. This is needed for tightening the 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.
-- Remove the wheel.
-- Turn the wheel hub until one of the holes for the wheel bolts is on top.
-- Install :T10149 with wheel bolt on wheel hub.
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.
-- Lift the wheel bearing housing using the :VAS6931 until dimension -a- is reached.
- 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.
-- Remove the :VAS6931 from under the vehicle.
-- Remove the :T10149
