O.k, now I'm a little confused. In previous posts on the topic of
squeaking appearing after installing lowering springs in the rear, the
consensus was that new control arm bushings were needed.
Where I'm getting confused I believe is figuring out what part the rear
"control arm" being referred to really is, and what part is really at
the root of the squeaking.
So far I have two possible culprits:
Possible Culprit #1:
Track Control Arms (ETKA)
Transverse Linkage (Bentley)
p/n 443 505 351 P -left
443 505 352 P -right
Possible Culprit #2:
Trapezoidal Arms (Bentley)
I can't even find this one in ETKA
Any insight you may be able to offer to clear this up for me would be
