re s-type jaguar spherical bushes/linkages and ball joints .check very carefully if there is no play in them it could possibly be only the dust caps that have disintegrated the dust caps are held on with spring clips at both ends .do a inet search for ball joint dust caps .you will have to get the arms/linkages off the car to get covers off by prying the clips off, couple of measurements are small end large end and uncompresed length of cover . hope this helps

 

tbird6, I have a 2003 S-Type V-6. The camber/toe lateral links part number I bought was LEM1828224 from Autopartsway.com. I am sure they would have what you need just plug in your year and model to see.
