Problems With Polyurethane Bushings

I installed Energy Suspension polyurethane bushings in my upper and lower control arms and rear strut rods last summer and set all of the camber angles to -0- degrees. Today I noticed the insides of my front tires were wearing very fast so I re-checked the camber angles and found the front tires had an average of .9 degrees negative camber and my rear tires had an average of 1.7 degrees negative camber. So it appears these polyurethane bushings squash pretty easily. I don't know if all the squash takes place in the first few weeks or if the squash is progressive and they'll continue to squash. As I'm going to be installing four new BF Goodrich T/A radials this next weekend I wanted to make sure my alignment is correct.

Have any of you noticed your alignment drastically changing right after installing new polyurethane bushings?

I did all mine in rubber about three years ago. Only because I heard the polyurethane ones could end up squeaking. Never heard of them failing like that.

Haven't had any problems with my plolies.

I have heard of them squeaking if the correct assembly lube isn't used and I have heard of them crumbling but I have never heard of them squashing like these did. After I got my four new tires installed I set the caster angles to the usual 2.5 degrees positive and the camber angle to .6 degrees positive. Hopefully the bushings have finished squashing and my alignment won't change.
