Default Suspension upgrades now getting a thump, thump.

So I finally installed my BMR non adj LCA, relo brackets, PHB and brace, Eibach pro kit springs, anti roll bar kit, and Koni struts/shocks and I'm getting a thump, thump, during turns coming from the driver rear. I TQed everything with the suspension under load so looking for ideas on what it could be.

Sound only comes when making slow turns. It does not sound like metal hitting metal. More like a dull thump, then half second later, thump.

Any ideas?

Thanks

Any chance your missing a bushing? Any chance something is in backwards therefore causing a rub and knock?

I had that issue with my BMR suspension but it was the sway bar it had come loose. Is your PHB adjustable?

I honestly don't remember how the bushing on the shocks are suppose to go (it looks rather self explanatory to me but that doesn't mean I did it right) but they look right.

Is there a chance? Always. Do I think I did install something backwards? No. Sway bar, shocks, LCA's, PHB brace, relocation brackets can only be installed one way. I did install the PHB the opposite way that Steeda has theirs due to the zerks fittings only being accessible one way.

Yeah I have the adj. BMR bar. Ill check to see if it came loose.

I purposely didn't post in the handling section as it doesn't get as much traffic but oh well.

Hey Matt, What about the handbrake cable? If that is not secured, or was not put back correctly that could slap around. Otherwise, it would be good to re-read the directions and maybe you missed something?

Handbrake/E brake cable is secure to the LCA's like directions instructed me to do I know its not that. I havent put the car back up on jacks yet to poke around but sounds like I am going to have to.

I have three different manufactures (Eibach, BMR, and Koni) so until I can find where the noise is coming from it doesn't do much good to call yet.

Are you talking about the PHB coming loose still? I am going to get my 4 wheel alignment done today after work so I planned on having the shop look into when they have it on the lift.

Did you torque all the fasteners with the suspension loaded at ride height?
Torquing with a fully drooped suspension will cause all sorts of problems you do not need...
