Re: Noisy Delrin Bushings

If you could push them in all the way by hand, something is wrong.  You
should have to press them in with a press or one of the make shift ways some
of the listers have developed.
I'd look at the control to see if it is in fact the correct control arm for
your car and not another Audi, and of course, make sure Blau sent the right
ones.

Later!
