Rear suspension clunking

[codyh]

Hey guys, first time posting on here, having a rear clunking noise I cannot solve and was hoping for some help / guidance.
I installed steeda’s dual rate lowering springs, with ford track shocks / struts. Got the car aligned and it’s right on spec and the noise was there prior. Every time I hit hard bumps, speed bumps, uneven surfaces it has a light clunk sound that seems to come from both sides it seems like near the upper rear end. Fwiw I have steeda’s stop the hop ultimate kit, I just replaced the rear sway bar with rtr, I did adjustable end links and I went and got near oem upper rear shock mounts and the sound is still there.

I had that too. Turned out to be one of the rear seat latches. Sure sounded like the rear end!

Did you install shorter bump stops?

I have a rear seat delete in my car. Otherwise I wish lol. Mine has all the latches removed.

Fords kit comes with shorter bump stops I checked though to be safe. They look around 3/4-1 inch shorter than oem.

Those should be the correct bump stops for a lowered car. Were all of the suspension bushings torqued at ride height?

Yes. I clocked them 2x just to be safe. I took the rear shocks off, inspected them looked ok. Re torqued them, changed to new oem rear mounts and the sound is still there. Only thing that seems weird is the springs seem to have different tension on them. One of them is looser than the other but both are properly installed and seated.

something ain’t right if that’s present

Sounds like you covered the common stuff... with an obvious difference in the spring size/tension, I may suspect a spring issue. Maybe time to contact manufacturer.

I wrote them today to be safe as well

Yeah on jack stands one spring is tight the other isn’t as much. You can’t literally move it but you can see there’s a difference in “ tension “ I would say.
