My 88 XJS probably needs to have the rear transmission support spring assembly replaced. I'm not really sure of what all the components are that I need to order. At the same time I will replace both drive shaft U-joints too. It has 93K miles on the odometer. Can anyone here tell me what part numbers I need to purchase?

 

51rover,

All in the usual place on the Jaguar parts website with part numbers and prices, if still available from Jaguar.

Good luck
