I took my 2002 S-Type (3.0) into a shop I trust to diagnose major squeaking from rear suspension. They told me the “bushings” in the rear control arms were the source of the noise. They were dry but not worn out. They went on to say the bushings weren’t rubber, like normal bushings. They don’t work on a lot of Jaguars so they don’t have many connections for parts. Any idea were I can get these “bushings” and what might be their real name?
Jaguar call these parts wishbones and only supply new replacements with the bushes already installed. They are expensive. However, many vendors on eBay sell bush kits. There are three bushes in the lower wishbone and two + a ball joint in the upper wishbone on each side. From time to time I have also seen exchange wishbones offered in the Jaguar magazines.
I too have put oil on mine because its my daily driver and I’m too busy and too cheap to get new ones. I take the wheel off and use a plastic squirt bottle with a tapered spout and a long hose. It works for a year or two.
