the first rear ipd sway broke about 3 years ago...it created this chatter that was annoying, especially over bumps. removed it and found that the passenger side welding (for the nuts) had broken off. replaced it and no problems.

just went to that little twisty road between st helena and sonoma (starts with a t, forgot name) in napa, nice spirited driving =). anyway, the rear feels clunky and noisy...will have to check it out again. quite possibly it broke again...sigh. there's just way too much stress on that funky delta link design (it's patented too...no doubt, no manufacturer's really gonna copy it)...the rear wheels are supposed to toe-in under stress. putting that bar there almost seems to limit that...oh well.
