Did you remove or cut down the bump stops on the top of the axle tube, just to the out side of the springs. See the attached photo.

To answer your question, yes it can cause noises. Regarding the bump stop, I didn't cut mine as there are no directions from Steeda to do this, and I have no noises.

It seems to me that the bump stop is there to keep the suspension from bottoming out- cutting it would allow the rearend to bottom out more quickly, unless I'm not understanding what the purpose of the bump stop really is.

Tom it's just the opposite. Cutting the bump stops creates more clearance between the foam "stop" and the chassis. You should cut your bumpstops off. It's a 5 minute job with a hack-saw.

No issues with bottoming out here either. Mine makes a few noises on speed bumps. Probably the stock LCA bushings creaking a touch as they are a little out of their stock range without relocation brackets. The slight creaking front and rear on speed bumps went away for the most part after everything settled. I have never come remotely close to bottoming out.

I would think that if you bottomed out with shorter stops, the stock panhard bar could conceivably snap.

with the Eibach Pro springs I only had an inch left between the bumpstops and the frame. You need to cut off at least one inch of the bumpstop with a small hacksaw to get more travel before bottoming out.It is soft rubber/foam and easy to cut.

Just for grins.. .. Listen real close to see if it is your trunk latch hitting against the catch bar... that can make knocking sounds over bumps. If you don't have someone to assist you, drop the rear seat backs to open up the trunk area.
