Re: Noisy Delrin Bushings

Blau suspected possible play between the upper strut rods and the mounts.
He suggested investigating this, and possibly installing some shims
somewhere between the mounting nut and the cupped washer which is just below
the upper spring retainer.  And then just double check the torques
everywhere.  But they admit that it is
possible (but not likely) that I have some off-spec bushings.

Best Regards,
