Sierra and Escort Cosworth owners fear no more, GGR appears to have an answer to the rear semi-trailing arm bush that is no longer available from Ford:
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=400060295109&ssPageName=STRK:MEWAX:IT#ht_2336wt_1169When this rose jointed bush starts flopping around due to wear and tear (or damage), the rear wheels will become capable of choosing their own direction of travel, add that to the bump steer from the "less-than-ideal" rear suspension setup and you've got a nasty recipe for disaster.
I had one of mine replaced several years ago (at an all in cost of nearly £300 - yes I was robbed but that was the only way it would pass an MOT!) and back then I was told I was lucky because they are nigh-on impossible to get hold of!
