Have got a 52 TDCI Focus. Just tried to change a worn bush on the sus arm just under rear n/s passenger door. Ford would only supply a bush fitted in the unit. Does anyone know where i can get replacement bushes.Also when trying to remove said part,all the other large bolts situated at rear of wheel, were stuck in their respective bushes. To replace all the rear sus arms would cost me about £300. Has anyone else had these problems and if so how did u get round them. Cheers.
