First I have Tein Basic Coilovers that are 10,000 miles old along with a new set of racing bushings. now I have some popping noise either in the suspension or pillow bar bushings in the rear of my FD. What i found out is some mixed messages about what the noise could be.

So the first thing I did was replace my upper pillow bar mounts and the popping noise kind of quieted down a bit but still there. So I searched and someone said that if you can move your wheel back and forth while jacked up a bit, then your pillow bar bushings are bad. Well my wheels do not move like that. So I hate to replace the bushings again but can someone give me some advice on what the next thing I could do or check? Thanks

 

There are 3 pillowballs on each side in the rear. Did you replace them all?

 

I replaced all bushing around 10000 miles ago with superpro bushing kit.....

 

The SuperPro kit does not contain replacement pillowball bushings. Those alone are around $400 from Mazda (where as the entire SuperPro kit is around $500).

Pillow Ball Replacement

 

This is the bushing kit I got
SuperPro Polyurethane Performance Suspension Bushings for Mazda RX-7 FD3S 1992-2002

 

As Mahjic stated, pillowballs are available OEM from Mazda. The superpro kit does not replace these. These are what we are referring to:



Locations are both right in bottom control arm, and left most in upper arm. Did you replace these as well?

 

I think your right. These are not in the kit and I personally did not replace them just had the kit. So does someone have a cheap store to buy these?

 

You can order these from my website www.j-auto.net or I can process your order personally.
