    Panhard Bar and LCA's

    I have a question, I just installed my new UMI panhard bar and LCA's combo on my trans am, i have not yet lowered my car or anything and this is the first suspension mod I have added. I installed everything according to the instructions and torked everything down to the specks, but now when im driving over small bumps in the road or in the parking lot the rear end makes alot of noice kinda like the bushings are grinding or something and the rear end makes like a jousting sound for a lack of better words. Is this sort of thing normal kind of like a set in period or are the parts binding, like i over torked the bushings? Any help or comments would be greatly appreciated, thanks.

    Did you grease up the ends like the instructions said? There will be more noise transmitted. It is a much firmer setup.

    If you have any solid ends, it could be that the adjustment bolt is loose and allowing the end to bind. Not sure of the sounds you are describing, but it that is the case it will sound almost like rocks being thrown up from under the car.

    I second the greasing, did you follow the instructions to the letter? I just put in UMI LCAs adn they are much quieter then stock. did you tourque them before or after the weight of the car was on the axel.

    I just put the bolts in finger tight before letting the weight of the car settle on the axel.

    I only know because when I installed my LCAs I did the same thing. The panhard if you have rod ends on both sides you will have to keep an eye on as they will start to bind up on their own, or at least I have not found a way to keep if from happening yet.
