I have a 1989 Jaguar XJ6. The shocks are making alot of noise and I don't know why. I think perhaps I might need to refill the mineral oil. Any ideas/information on mineral oil system?
It sounds like your XJ6 shock absorbers are about worn out. How many miles on your XJ6? It would be smarter and more cost effective to replace your old shock absorbers with new heavy duty shocks.
