Recently I have had some problem with the rear GB suspension, being loose and wobbly.

Someone told me the FOAM SPRING BUFFER PRODUCT CODE: MHG7566AA* is the most likely culprit.

Does anyone know if there are other parts that I should consider replacing?

Grateful for any help!

 

Hi Roland,

There are three rubber components that you will want to replace. Part 7 in the diagram is the large foam rubber buffer, and Parts 3 and 11 are rubber spring isolators that tend to deteriorate due to oil contamination:




You can confirm the part numbers here:

Transmission Mounting-Rear - Parts For XJ6 (2.9, 3.2, 3.6, 4.0) from (V)500001 to (V)667828 | Jaguar Heritage Parts UK

And it would be worth checking the part numbers at jaguarmerriamparts.com to see if there have been any more recent part number supersessions.

Note that the order of the components shown in the diagram above is correct. If you refer to the Haynes manual, the photos show an incorrect assembly order. Haynes shows parts 5/6 fitting on top of Part 7, but that is incorrect. As the Jaguar diagram above correctly shows, the locating weight, Part 6, fits inside the spring cradle (a metal cup), Part 5, and the foam buffer, Part 7 fits on top. If you follow the Haynes instructions, the mount will not perform correctly.

Cheers,

Don
