I have a 2007 Saturn Outlook, FWD. I just got finished changing the stabilizer bar bushings using Moog parts, and u had a bit of trouble. One, the bottom part of the bushing instead of going on into the steel caps, the caps hung on the outside edge of the bushing. Once I fought that in and tightened them on down, there's about an eights of an inch gap between the top and bottom of the rubber. Should I have greased the caps or the bar? I saw that GM has two different part numbers, one for AWD and one for two different RPO's in FWD. Surely moogs part is for the FWD?
