It's probably the bushings. Do a search, you'll find lots of info.

 

thanks for reply, but from what i remember bad bushings make squeeky noise but mine sound loose.. when it rebounds...

 

I've got supra TT eibachs and Bilstein shocks and have a question about the assembly of them. They are currently completely assembled and I was wondering if there is suppose to be any rubber/padding were the bottom of the coil and the shocks come into contact. As of right now there is only metal to metal contact. I'm thinking about putting 1/4 piece of rubber inbetween them to eliminate the metal to metal contact. Is this a good idea or would it cause some problems? Also, the spring is a little loose in the assembly. Is this normal? I'm sure the spring would become compressed once installed. I'm just trying to make sure I eliminate any noise that might occur.

Here is a picture of the assembly. You will notice near the middle of the assembly, the metal to metal contact.

Thanks

 

I used the rubber from the upper mounts but I believe there wasn't any for the lower part.

 

There is no need for rubber between the spring and the seat. According to Eibach, it's recommended that you leave 1/4-1/2" space between the end of the coil and the seat pocket. This will help prevent spring noise when encountering large bumps.

Check out Eibach's tech tips from their website.

Ahh.... I missed the tech tips section. I only saw the FAQ. OK, so the spacing is good :/check:.

The tech tips section also says "OE spring isolator pads are crucial in isolating road noise from the passenger compartment. If your car has more than 50K miles, it may be necessary to replace the worn-out OE isolators. If your isolator pad has worn thin or through, it must be replaced before installing the Eibach springs. All Eibach springs are designed for use with new isolator pads. Failure to replace worn pads may result in excessive noise and improper ride height."

Does the stock suspension have "isolator pads" near the bottom of the spring (I can't tell on my car, they might be thin or worn through)? It would make sense to have pads on the top and bottom to prevent noise. Just a thought.....

 

Neither my 92 SC4 or my 95 SC4 had isolator pads on the bottom.

 

with a stock suspension with 100k on it would the isolator pads most likely be the problem of a squishy clunky noise when going over railroad tracks. i had changed my bushings to the poly bushings a couple months ago and it increased the noise. should i try to change the isolator pad or should i try to put a fuel hose on the stock springs?
