Dear Gents. I've got a 98, V8i Two door Disco and over small road bumps etc the steering goes a bit crazy, like the shakes after a hard night partying! My mechanic tells me in his pigeon English that it's at the "end of the steering and it's a common fault". He's tighten it up but "will eventually loosen up". Could someone try to identify the worn part on the attached file and let me know what supplier could provide a replacement? Many thanks. (I would ask my mechanic but he's a bit flakey himself and need an expert. )
