Wheel Bearing In Curb Weight Position, 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 have a limited range of motion.
- Axle components with bonded rubber bushings must be brought into the position they will be in when driving before they are tightened (curb weight position).
- Otherwise, the bonded rubber bushing will have tension, which will reduce the service life.
- By raising the corresponding suspension using the :VAS6931 and :T10149 , this position can be simulated on the hoist.
-- Before starting the procedure, determine the measurement -a-, for example with tape measure, from the center of the wheel to the lower edge of the wheel housing.
The measurement must be performed in curb weight position (unloaded condition).
-- Note the measurement. This will be needed when tightening the bolts/nuts.
Risk of accident!
- A vehicle that is not secured can slide off the hoist.
Before the applicable suspension is raised, the vehicle must be secured to the hoist lifting arms using :T10038 .
-- Turn the wheel hub until one of the holes for the wheel bolts is on top.
-- Install the :T10149 with wheel bolt on wheel hub.
-- Lift the wheel bearing housing using the :VAS6931 until the dimension -a- is reached.
Tightening of the applicable bolts/nuts must only occur if the dimension -A- that was measured before installation has been attained between the center of the wheel hub and the lower edge of the wheel housing.
Risk of accident!
- Do not lift or lower vehicle with the engine and gearbox jack still under the vehicle.
- Do not leave the :VAS6931 under the vehicle any longer than necessary.
-- Tighten the applicable bolts and nuts.
-- Lower the wheel bearing housing.
-- Pull the :VAS6931 out from under the vehicle.
-- Remove the :T10149
