On an E30, is it difficult to push a new rubber control arm bushing onto a new control arm? Is there a substitute for the BMW Special Lubricant/Glue (part no. 81 22 9 407 284)? I have a 1987 325i convertible. Needless to say, I have never replaced the control arms myself and mine are worn again. I purchased new control arms and the bushings pre-assembled into their mounting brackets from Bavarian Autosport thinking that it was a fairly simple job. However, I now read in "101 Performance Projects" (P174 first paragraph) that, "I strongly suggest you have a machine shop press the new bushings onto the end of the control arm." Wayne Dempsey does not seem to be referring to pressing the bushing into the bracket, but rather the bushing onto the control arm itself. Bentley makes no mention of such difficulty. Can I do it myself while lying on my back underneath a car?
