Steering Geometry - Check

Suspension Geometry - Check

1. The close tolerance machined alloy subframe installed on NA vehicles with VIN up to 031302, precludes the necessity for adjustment of front suspension geometry during vehicle manufacture. Eccentric lower wishbone fulcrum bolts are available as service items, but should only be fitted when directed by Jaguar Technical Support.

On RHD and Japan market LH drive SC vehicles with VIN up to 031302, eccentric fulcrum bolts securing the lower wishbone to the front crossbeam, facilitate adjustment of wheel camber.

All RH drive and Japan market LH drive vehicles from VIN 031302, incorporate a long upper wishbone on the RH side of the vehicle and a short upper wishbone on the LH side. There is a 2mm difference between the two wishbones, measured from the centers of the ball joint location and the fulcrum bolt location. The longer wishbone is identified by a countersunk hole in the upper surface adjacent to the ball joint location. All other LH drive vehicles from VIN 031302 onward are fitted with the shorter upper wishbone on both sides. These measures counter the effects of road camber on steering and eliminate the necessity for adjustment of suspension geometry.

NOTE: The vehicle must be checked to establish that it conforms to the Jaguar original specification, e.g. wheels, tires, tire pressures, etc.

NOTE: The "space saver" wheel must not be installed on any of the hubs when measuring suspension geometry.

NOTE: The vehicle must be unladen and the fuel tank full when measuring suspension geometry.

Whilst fulcrum bolts remain available as service items, a suspected suspension problem must be reported to Jaguar Technical Support on the "Suspension Geometry Record Form" provided and Technical Support consulted, before any adjustments are carded out.

2. Road test the vehicle to establish the exact nature of the complaint, e.g. pullubg to one side, wander..

3. Measure the suspension geometry, fill in the 'Suspension Record Form' and contact Jaguar Technical Support for assistance

4. Technical Support will give advice in the course of action to be taken to recify the problem.
