after doing th efront end and using moog lower ball joints on the dart years ago and it never feeling right. it was twitchy deeling and i couldn't find anything out of the ordinary. after reading about the crappy moog stuff that was out there i said screw it and replaced the lower ball joints with XRF lower ball joints.. as soon as i backed it out of the garage i knew it was fixed. something in the one ball joint was binding or something.... not sure if XRF still make them for our cars though. it was hard to find them at the time.. i think it was proforged maybe (not sure if thats the correct name or not) that a lot of guys seem to like on various car forums i've seen..
