This is my first post on the S-Type forum, although I am always posting on the XJS and X-300 forums for my own cars. I have a friend who has a 2000 S-Type that has an issue and so I’m asking for her.
The problem she’s having with her Jag is the same type I have had before on all my Jags, whether an XJ40, X-300, XJS or XJ8 – namely, front upper shock bushings (typically the yellow foam crap Bilsteins) gone bad … However, looking at a diagram of the front suspension for the S-Type on the Classic parts website, it looks like the setup for that type of Jag is quite different from that of the others mentioned. Specifically, I don’t particularly see anything analogous to the upper shock bushing that would go bad over time, resulting in a loud, metallic “clunk” whenever the wheel travels over potholes, road bumps, etc. So, looking at the S-Type setup, I suspect what may possible be wrong with my friend’s Jag is either a bad “spring insulator” disc or a bad “shock mount” for both front wheels (or both). It doesn’t help in that I don’t know what material either part is made of (e.g. metal, rubber, etc.), since I am only going by the drawing and photos of those items for sale on Ebay.
Do either of these parts have a reputation for going bad over time, resulting in the issue my friend’s Jag is experiencing?
Thanks for your help.
