Ok so I'm finally getting around to my suspension and rear Si disc swap. I am replacing the rear trailing arm bushing with a OEM bushing due to the reports of "binding" or 'lack of movement allowed' to the arm. -- I do have the hyperflex bushing kit for my Civic. My question is: are there any other bushings that anyone would hesitate to replace with Polyurethane?

Thanks guys

the only bushings i WOULD CONSIDER replacing with poly is front upper control arms and lower shock bushings, front back, and swaybar bushings. and thats if you can stand the noise.

i name these because they either are designed to only allow one degree of rotation, or i dont care. poly bushings are really designed to accomodate only axial rotation.

because the upper control arm bushings are paired and in line with each other, they by nature only allow axial rotation.

with the shock bushing, since its not part of the suspension geometry, i dont care, and it should be stiff as possible, to let the shock do its job. i would not go as far as TOTALLY constraining it like someone tried by using two spherical bushings to lock it in place, but poly would be a fine alternative there.

again, with the swaybar bushings, they are supposed to only have axial rotation. but i hear they tend to squeek a lot. H&R has some nice teflon lined swaybar bushings, not sure if they are available separately, but looks like a good concept.

the rest of hte suspension bushings i would leave stock rubber.

Good call on the Axial rotation, Tyson!!! Thanks for the info
