^^^ Completely agree. :tup:

That sounds EXACTLY like when my sway bars were loose. I didn't get enough torque on the sway/end link bolt when we installed them. That's the first thing I'd check and it's pretty quick and easy. I would grease the bushings while I was down there too if they have zerks.

thanks! sorry to sound like a noob, but 'zerks':confused:? what kind of grease should i use.

you are giving me hope :tup: are these the bolts that 370zforme posted pictures of?

is this the sound too? i think thats pretty similar to what i have going on sound-wise.

Its kinda hard to tell from the first videos, but if it is that constant rattling noise you should take a look at your pillowball mounts. I have have owned several sets of coils on my other vehicles, and when the pillow ball upper mounts wear out they will make that exact same noise. You should check to see any play in them not only fore and aft but also up and down.

It may be loose.

well its only been 3 weeks, so they shouldn't be worn out, but how do i check for play?

Zerk is just a term for grease fitting. If you have the stock sway bars you won't have any. I just use regular lithium grease. That video sounds about right to me too.

370zforme's pics are pretty good. The bolts circled in black were what were loose in my case. Takes two wrenches to tighten them iirc. Check both sides just to be sure. :)

thanks, i will try this tonight, hopefully all goes well. is there any torque spec or just as hard as i can?

I think it is 110lb-ft but I could be wrong.

so basically, really damn tight. i have a torque wrench, if it fits in the area i guess i'll use it, but i guess it would be kind of easy to tell if they were lose.

The rear sway bar mounts are torqued to 33 ft/lbs and the end links are torqued to 41 ft/lbs (see my install thread).

My sway bar bushings dry up pretty quickly, I re-lube them every 6 months. That tends to make more of a creaking noise though.

Make sure the spring isn't loose in it's perch when the rear is unloaded, if it is then the rear shock needs to be adjusted.

I am not saying they are warn out. I am just saying maybe you should try retightening the top mounts.

Also 110lbs for sway bars, is rediculous. Thats tighter than wheels lugs, or just about anything else on the vehicle. Maybe the Axle bolt might be about that range, but I dont even think the axle is that tight.

Anyways jack up each corner so that there is no weight on the shock and shake the shock around to see if you can recreate the sound. That should help you better pinpoint where the sound is coming from.

how do i tighten the top mounts. is that the part under the adjuster?
i will try that tonight. the sound is definitely coming from the right rear so i will try that for both.

thanks so much to everyone chiming in to help out, i really appreciate it!

Gah. You're right. I don't know what made me think 110.

so i spoke with BC and they said it sounded like an issue with the preload on the spring. He sent me this on how to adjust it.

I had a noise somewhere toward the rear end when I installed my coilovers. I was stupid to what the noise was. I first though it was the top shock mounts in the rear, then I thought it was the shock itself. I checked and rechecked but everything was tight. What I discovered was that the foam fill in for the spare and stuff was the culprit. I know it sounds insane, but when I stuffed a rag to snug everything up back the the noise stopped. I removed my spare so the passenger side foam insert was loose and rattled while I drove. My shock are set somewhat stiff so it rattled quite a bit. It doesn't hurt to check that. I keep the rag there for now until I figure something else out. Carpet back there cover it up anyway. Hope this helps.
