I have noticed that about 6 months after a ZX2 w/ Eibach Pro-Kit install, there is a squeaking sound coming from the rear struts (I think) when I push down on the rear or go over speed bumps.

Also, my hatch is making some weird squeaking noises when I drive over bumps and I cannot isolate where it is coming from. I checked the weather stripping, lubed it with Silicone Spray and still annoying as hell.

Any Ideas?

I believe the squeaking comes from the rear springs shifting against the rubber seats that wrap around the rear strut mounts. I just did the ZX-2 Tokico/H&R Spring swap, and I've got the sqeaky sound too. I reused the rubbers. Perhaps if I'd bought new ones, or lubricated them they wouldn't squeak.

just a thought but it may be the jack wiggling or the jack raise-lower bent bar making that noise!

I've got nothing in my trunk. No spare, jack, or rod.

You can tighten the hatch lock, just loosen the bolts and shift the catcher (IIRC)
I also wrapped the other bit in insulation tape, its worn through now and still doesn't squeak, so it probably wasn't necessary

Ok the sound has gotten worse from a squeak to almost a banging sound when I go over bumps. It definitely sounds like the sound is from inside the car, and the hatch doesn't seem to be the culprit...I cant help but think that maybe my strut mounts are involved because last I looked at them they were very rusted out and I was an idiot and failed to replace them when installing the ZX2's.

...here is a pic taken a few weeks ago when I installed the CS rear strut tower brace... will check tomorrow to see if they are worse and if that is what im hearing

That sounds to me like a sympton of a failed strut. Once the hydraulic fluid leaks out, the strut has no damping effect. Even though the spring is there, when you go over a bump, it feels like the car has smashed into a brick wall.

This is what happened to my rear struts, and the reason I did the ZX-2 swap. When I removed the stock struts, I could literally push the shafts down and pull them up with absolutely no resistance. They were also coated in fluid.

So I looked and it is definitely my rear passenger side strut mount that is completely rotted out. The Strut assembly is moving freely underneath the rear seat belt mount due to the deterioration of the strut mount. I will have to replace them asap

Temporary fix: shove a washcloth underneath the seatbelt mount so it doesn't hit the top and make as terrible of a noise over bumps...

Permanent fix: I will either buy MS Rear Strut Mounts or use some used ZX2 Mounts. I don't know which is best, the latter is cheaper but I don't want the same problem. Any suggestions? I suppose if I get MS Mounts I will eventually chance the fronts too.
