I had installed a set of Steeda Billet LCA's a couple of weeks ago along with a adj panhard bar. My traction is phenominal now. The only thing is that I now have a clanking/rattling noise coming from the rear. Mostly from the right rear. It sounds like metal on metal, almost like something is bouncing around in the trunk. I thought maybe my jack was loose, but is was bolted down tight. I get the noise when the road is bumpy, especially at slow speeds. I don't have any problems on the FWY or at high speeds.

I've heard of aftermarket LCA's being noisy, but do the sounds I'm describing sound normal?

Thanks.

 

I'd say either your adjustable panhard bar came loose, happened to me, or your muffler is on that side is making contact with the frame.

 

I have the same thing since putting on my GMS LCA's. l get a thunk back there at low speeds. I think it's a combo of the urethyene bushings and the diff when it gets loaded and unloaded with the tranny at low speed.

 

I had that issue on my own 06, it was the muffler for me too, but do check the panhard rod too make sure its tight.
