I installed the eibach pro-kit, and the BMR adjustable LCAs with the rod-end at one end and the poly bushing at the other end. Now I have a very loud rattle coming from the rear suspension. I put the car back up on jackstands and retorqued everything, but the rattle persists. I thought you guys may have a different idea on what it may be. Any input is appreciated. Thanks in advance.

Is it a rattle or a "creeking" sound as you go over bumps? I found that putting some teflon based lube on the rod end help quiet down those solid ends.

it's definitely a rattle, sounds almost like something is loose, but I checked and everything seems OK. Anyone else with ideas. Off to check under the car again.

I went out and gave the LCAs a good tug, and they move ever so slightly. I torqued them according to the BMR instructions, but I also remember reading that they should be torqued to 130 ft/lbs instead of the instructed 75.

Try the lube and let us know. I too thought my LCAs were loose or the bracket broke. I checked them and everything was fine. I added a little teflon lube to the rod ends and no more noise.

Did you trim the rear bump stops during installation? You could just slightly be hitting up against them...
