Sway bar end alignment

[Norm Peterson]

I've been chasing a 46-48 mph oscillation as David descibed. My bar ends are slightly angled up because of my lowered suspension but I don't feel I can shorten the end links any more. I backed off the end link nut (poly bushings) until I could barely twist the bushing washer and my oscillations went away.

Maybe try recontouring the poly pieces and the washers to be better approximations of a rod end when assembled. The more angular freedom you can get from sliding movement and the less that you rely on compliance, I think the less likely it will be that these side effects [of poly's relatively low compliance] will show up as functional problems.

A little taper in the hole to accommodate endlink bolt angular movements, and more or less spherical shaping of the ends of the poly not in contact with the bar or control arm (and also the washers) isn't that hard to do. I think you'd want the spherical surface diameter to be the distance between the two washers as assembled/installed, which will not necessarily be equal to the bushing OD. You trade a little effective sta-bar stiffness for better endlink behavior.
