Thanks guys.............I feel I'm narrowing down my 'clunk'

I'm becoming obsessed to the stage that it is ruining what is really quite a smooth ride

I'm now convinced the 'clunk' also comes with braking while turning and the first brake after change of direction (back to forward) ........but it is a bit variable.....AHHH!

My latest thought is the guide / track rod bushing......#20........seems changes in the longitudinal forces strain this bushing

I read your thread donbryce.........will have to work out a way to unload this bushing to check it.......I have a come-along / hand winch so will try pulling the LCA forward at the weekend........mine is a w123, but I suppose similar except for the subframe

I guess I'll end up replacing everything that doesn't require removal of the spring........so would have to leave the lower ball joint to a Suspension Tech
