what car?

a 123?

it may be that you did not get the bushing seated fully. you are only referring to the 2 bushings which are under the rear doors? the only reason I can think of off hand is the bushing is not fully seated. they are a bear, I guess I kept a 18" breaker bar and socket in my car for a month, tightening down the big bolt every few days until it was fully seated.
