I'm replacing the stock rear upper/lower control arms with a set of Macs on a 1992 GT 5spd 5.0. Now with the Macs, it keeps eating the bushings up when the car is'nt really driven everyday nor driven hard. I'm also trying to put in the Energy suspension bushings,they seem to be larger than stock even though the are the correct part for my car. (Part # 4-3114 ) I'm I missing a step in the install?

 

this has nothing to do with buying Ford parts from randy.

 

sounds like either your pinion angle is off or your tq boxxes are trashed, or all the above.
