[QUOTE="DMassey, post: 16122440, member: 26299"] just checking in for the sake of those who may do a search in the future... I took the car for a test drive last week when we finally had a nice break from the deep freeze and had enough rain to wash the salt off the roads. I was unsatisfied with 2 things: 1. I had a nasty harsh clunking in the rear under a hard bump 2. the rear wheels weren't centered in the fenderwells just right. Fixing the IRS cradle alignment was easy enough. I bought a set of Steeda ST-5554447 IRS alignment bushings for use with BMR CB005 cradle lockouts. It is said that the BMR CB005 cradle lockouts act as a self centering device for the IRS, but my experience says not so. Last night I installed the Steeda IRS alignment kit and the wheels are now properly located in the fenderwells. Kelly Aiken, and some internet searching, helped point me to where my rear clunking noise was coming from. Alot of people have this issue when they install the BMR TR005 adjustable toe links, but it's pretty much always poor installation... as was the case with myself. When these are installed, you are instructed to install the bearing housing straight up and centered over the bearing end. Where many people error, myself included, is you are supposed to center the bearing housing while the rear suspension is loaded. My installation error was centering the bearing housing and torquing the bolts with the suspension in full droop. Therefore, when I hit a bump, the bearing end was bottoming out. [b]It is very important to torque these bolts and center the bearing housing while the suspension is loaded.[/b] The bearing end of the toe link has alot of articulation when the suspension moves, so you have to make sure you have it adjusted so that the bearing housing does not bottom out. When the BMR TR005 toe rod is installed properly, you should see no increase in NVH. [/QUOTE]
