[DeTomaso] [POCA Forum] A-ARM BUSHINGS (Pantera Technical)

[Stephen]

I suppose it depends a bit on the tires you are running - and rims.  With
the stock 15's and the T/A's, I was pleased with the ride when my wife and I
ran up to Tacoma for a PNW group get together this week.  And, if one uses a
Teflon-containg grease - heck, the squeaky thing is not there.  Been using
urethane bushings in my XKE for many mines and no squeaks.  But, heck, if
ungreased, or with something like WD40 which has a rather short half-life
even if one doesn't drive the car...

Ah yes, life is but a trade-off. Stiff and squeaky or softer and quiet, The
older you get, the more you like the latter.
