My car seems to drive funny, the arms are stock replacement but with a harder bushing I got them from steeda 99 buck for both!! Will I need to realign?
You, Sir, are 110% Correct!!!Polyurethane bushings are a HUGE no-no in UCAs. With the stock triangulated 4-link, you HAVE to have either the bushing deflection provided by soft rubber bushings or the freedom of movement you get with spherical bushings. Without that, you'll just cause the suspension to bind. The fact that Steeda even sells these is just one more reason I can't stand that company.
Definitely check the mounting points (especially the chassis side) for crack/breakage/looseness, but my money's on the bushings causing this issue.
