Has anyone replaced their rear trailing arms with the TC Sportline arms off E-bay? They're like $150. My pass side bushing is shot and apparantly I can't buy just the bushing, but only the whole trailing arm. What have you guys been using? There's also a cheaper set on E-bay for like $100, but I know enough to be careful about cheap E-bay stuff. Any ideas? A stock replacement is still $260 after a 20% discount and that's for one side.
