Bob,
Did you mean that the leg came all the way off? With the circlip in place the leg will slide down until the upper bush meets the lower, then stop, as I'm sure you well know. The point I'm trying to get to is that losing the circlip does not have to destroy the bushes for handling trouble to pop up, as the upper would be up out of the leg and doing nothing. The bottom would eventually see damage, but it wouldn't be the root cause of the handling issue. (Reading this, if it sounds like I'm in some way sure of myself it's because I'm a good bluffer.) So, ultimately, you're saying Mt. Olympus is brimming with circlips, right?
