ISSUE:
Jaguar Cars recognizes that many independents are offering rear suspension springs and dampers as a lower cost alternative to replacing the ride leveling
struts. In an effort to help dealers retain these customers, Jaguar Cars is now offering a factory tested and approved spring and damper conversion fully
covered under the Jaguar Cars 12 month/unlimited miles parts and labor warranty when installed by a Jaguar Dealer.
Once completed, this conversion will effectively change the rear suspension specification to that of a 1994 MY sedan. Since this conversion deletes the
ride leveling function of the rear suspension, it can only be offered as an alternative to the repair of the ride leveling system - at the owners discretion.
You must document the customer's authorization with a statement on the repair order indicating the ride level function will be deleted.
ACTION:
Deactivate the ride leveling system, remove the ride leveling struts and install non-leveling rear dampers, using the following procedures:
^
Clamp a new non-leveling damper across the lower mounting eye in a vice. Apply multi-purpose grease to the guide bushing bore and upper face
where it contacts the top mounting plate. Using spring compressor tool number JD 125, build up the rear damper assembly in the sequence shown.
^
Install the top nut and tighten to 23 to 28 ft-lbs.
^
Repeat previous operations on the second non-leveling damper.
^
Remove the luggage compartment front trim panel and locate the rear axle harness connector:
On 1988-92 MY vehicles, the connector is a black, 8-way PM4.
On 1993 MY vehicles, the connector is a white, 8-way multi-lock.
^
Remove the following wires from the rear axle harness side of the connector:
