Re: Noisy Delrin Bushings

    What did Blau say when you asked them these questions?  They have had 
much more experience with these bushings than probably any of us..

for
 the front and rear lower control arms on a 4000q?  I installed a set last
 week, together with the H&R springs to complete the suspension upgrade that
 began with Boge Turbo Pro struts.  The bushings pressed into the lower
 control arm mounts a little easier than I expected.  The instruction sheet
 indicated that after initial hand assembly, the bushings would need to be
 driven home with an arbor press (something like the OEM rubber bushings, I
 expect).  However, we were able to push them home essentially by hand.  When
 the car is driven, I can hear the bushings moving around within the lower
 control arm mounts.  I can also bounce the car by hand (its hard with those
 springs and struts!), and hear the slight movement between the bushings and
 the control arms.  I trusted my mechanic to properly torque the control arm
 mounting bolts (to 60 Nm or about 43 ft-lb), and I had him check it again
 today.  But is it possible that they need to be torqued again?  I assume
 that he torqued them up with the weight of the car on the suspension as
 required by the installation instructions (and indeed the Bentley manual),
 but if not, would this lead to excessive play between the bushings and the
 control arm mounts?  Or is it possible that the bushings I received were
 off-spec?  Or finally, are these things just normally somewhat loose in the
 mounts and noisy?
