I replaced both beer can bushings on my 1990 735iL about a month ago. Today I looked under the car to see what was causing a squawking noise and found that both bushings had backed out and that the body was sitting on top of the subframe. I suspect that what I did wrong is that I used an industrial rubber lubricant and didn't allow enough time for it to disperse before putting weight on the bushings. Am I going to be able to shove the bushings back into the subframe? If I do, will they stay there?
