I am about to replace the idle arm bushings in my 86 300E. According to the manual, it does not seem complicated. However, once you loosen the nut and bolt, it looks that there is not enough cleareance to remove the bolt and the exhaust may be on the way. Is there a easy way, tips or shortcuts to do this procedure, without removing the exhaust piping?
J.H.
P.S. The whole front end is new.
