Wheel Bearing In Curb Weight, Lifting Vehicles With Coil Spring

WARNING: This page does not describe the selected car, but rather 13 other vehicles, including the 2017 Audi SQ5, 2017 Audi Q5, 2016 Audi SQ5, 2016 Audi Q5, and 2015 Audi SQ5. However, it is still accessible from the selected car via links, so may be relevant.

Special tools and workshop equipment required 

NOTE:

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 have tension, which will reduce the service life.

By raising appropriate suspension using Engine and Gearbox Jack VAS6931 and Engine/Gearbox Jack Adapter - Wheel Hub Support T10149, this position can be simulated on the hoist.

-- Before starting the work, take measurement -a-, for example, with a tape measure, from the center of the wheel to the lower edge of the wheel housing.

Measurement must be performed in curb weight position (unloaded condition).

-- Note the measurement. It will be required for tightening bolts/nuts.

Before appropriate suspension is raised, vehicle must be strapped to lift arms of hoist using Tensioning Strap 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 Engine/Gearbox Jack Adapter - Wheel Hub Support 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 Engine and Gearbox Jack VAS6931 until dimension -a- is reached.

WARNING:
  • Do not lift or lower the vehicle when the Engine and Gearbox Jack VAS6931 is below the vehicle.
  • Do not leave the Engine and Gearbox Jack VAS6931 under the vehicle any longer than necessary.

-- Tighten the bolts and nuts.

-- Lower the wheel bearing housing.

-- Remove the Engine and Gearbox Jack VAS6931 from under the vehicle.

-- Remove the Engine/Gearbox Jack Adapter - Wheel Hub Support T10149
