I'm undecided about these really. I like the idea of not having to do the job again but I'm concerned that poly isn't the best solution, and as I've read from others poly can squeak. It's also not very forgiving as far as cushioning. I have already ordered in rubber so that's what I'll install but I might get a set of the poly and put it on the shelf for when the rubber falls apart, which they will.Wish I had waited and got the polyurethane now, that job is one I'd rather not do twice! But my brakes are better now, so I guess it brought more good than bad
You could be right, I hear difference of opinion on it though. Some say the squeaking gets to be too much, others that it might cause more stress on the beam mounting brackets where connects to the body.I'm sure poly would be fine, since it's a pivot point. The springs and shocks are doing most of the work.
