It comes hard being the age I am but this am off came the offside shock absorber. Did the usual checks and the shock absorber seems fine. As is the spring. The bottom bush is OK BUT at the top, above the dirt cover is a washer on which the bottom of the two rubber bushes sit. This was loose as was the sleeve that governs the distance that the top nut can be screwed down to. Shaking the shock produced a loud rattle!!!!!!!!! The sleeve was also loose but would only move about 10mms up and down. Looking at the set up when all is in place the washer on top of the shock absorber should in theory be tight when the whole lot is in position, that is washer, rubber donut, hole in body, donut, washer and then nut. IF the rubber do nuts are a bit slack I wonder if movement allows the bottom washer and sleeve to rattle. Theory says other wise but the sleeve on the top of the shock absorber appears to have been manufactured as a tight fit as there appear to be press marks on it. I have put it all back together and did the bounce test, no rattle but a road test will be the answer. I put a piece of very thin rubber tween the dust cover on the shock absorber and the washer if the noise goes then I know what is the problem. Obviously it won't last long but it will be an indicator. Otherwise it's back to the drawing board. Yes the exhaust is fine, and I could find nothing else loose or moving where it shouldn't.
