Extremely annoying rear end clunk

Hey guys, I've been trying to diagnose this extremely annoying clunk coming from my rear passenger side for 2 weeks. It's most noticeable around 25-35.I checked brakes to see if maybe something was seized or that the parking brake was stuck, but no dice. I'm completely stumped. Any ideas?

More details...you mean a clunk when you drive over bumps or step on brake pedal?

My GT had a clunk that was only heard going over sharp bumps like pot holes or speed bumps...ended up being the upper LCA bushings.

Ohh no, it's just there when you're driving. It honestly reminded of me of the sound a bad axle joint makes on a truck, but it's only noticeable at certain speeds.

Endlink comes to mind. Sometimes the strut hats make some noise too. Not too bad to replace them if you have a spring compressor.

I actually thought endlinks too, and my one is shot, but I almost feel like it's too noisy to be them. I'll have to take my strut off tomorrow and check it out.

Any suspension mods?

 

Check endlinks, sway bar bushings/brackets, struts, top hats, etc.

Brackets are a good call too the rear sway bar reinforcement brackets are a weak design. I've hear of them breaking under load of aftermarket sways but I suppose it could happen with OE...

Lowering springs, but nothing other than that. I've checked everything over and I'm starting to just thing maybe it's a wheel bearing now. Though when the last one went bad it didn't sound like this.

I also started to think about the axle itself. How often do the rears go out?

Lowering springs take down strut life immensely. I've personally had struts that made no noise go bad in 2k miles after lowering car. I would consider Koni inserts with any lowering spring...I'd do top hats while things are apart.

 

Wheel bearing wouldn't clunk...it would whine and get louder with speed regardless of terrain. If you put the car in the air and wiggle the wheel it should have no play. If it rocks around your bearings are shot.

I know wheel bearings are more of a ring, but at this point I'm stumped. I need to just rip my strut off.

I would replace your endlink you say is shot then go from there. You would be surprised how loud those can be.

Check to make sure that the spring isn't rotating in the perch.

Broken sway bar mount ?

I had a clunk when I hit a sharp bump. I thought it might be a worn rear shock mount. I replaced them (and the rest of my suspension). The suspension pieces were serviceable. The shock mounts were toast.

Sway bar mounts are fine actually.

I haven't really got to mess with it in the past few days because of the rain, but as soon as it let's up ill check the spring, But it actually doesn't really make noise on bumps. It's more of a constant noise like the tire is rubbing/slapping off of something. But again, I've checked and there's nothing hitting it. So it has to be something with moving parts.

 

Usually I'm good at figuring out what's making noise. I even thought maybe it was a bent wheel, so I rotated tires and it's still there.
