I am looking to replace the radial arm bushings on my 93 EB 4X4. I was wondering about using polyurethane bushings since I know they generally last longer than rubber. After talking to one of the mechanics at a local shop, he said that the poly are too hard for this location and cause more problems than they are worth, also said they tend to crack (I'm guessing he cold doesn't help either). Suggested I use these heat resistant rubber ones instead. Any experiences? I know the poly will really tighten up the front end, but will it make it too tight and harshen the ride too much? I'm just trying to tighten the slop in the front end (wonders a little much) and quiet the thump that has gotten louder since the -30 degree weather has come along.
Thanks in advance,
Joey
