Suspension Noise - Right Rear - FD 3rd Gen - Please help...
Suspension Noise - Right Rear - FD 3rd Gen - Please help...
Hey Guys,
I get a repetitive popping sound from my right rear suspension when it is being loaded (on bumps and on left turns). I checked the torque on the upper strut mount nuts and visually inspected the bushings and the mounts underneath. Everything seems ok. Also, the bushings have been replaced w/ in the last 10K miles along with the struts.
Any help locating and/or curing this popping/ banging would be much appreciated.

It's dark like Poe.

Are you SURE it's not the bushings/hiem joints? I replaced the three control arm bushings on either side and it REALLY helped.
If it's not, is it possible that your OEM tool kit isn't secure?

Check this post (ignore the shocks comment as that was for something else):

Inspected again today. Wheel does not have any unusual movement characteristics when force is applied to the unloaded right rear. Also, the toe link condition seems to be equal between the right and left sides with no additional bushing slop on the noisy side.
Other attempts to cure the problem was to complete empty out the car of loose items and questionably loose interior paneling. I also lubricated all the bushings and strut staff.
Any other ideas where to look? Should I buy some coilovers to see if that fixes the popping/banging noise.
Just kidding, I always look for an excuse to mod.

How do you lubricate the bushings? (Unless you have a jimlab set.)
What do you mean when you say all the bushings were replaced recently? You mean all the rubber control arm, rubber and pillow ball bushings, and the trailing link, and toe control rubber bushings? What about your differential mount bushings and anti-roll bushings?

I believe there are 6 standard rear suspension bushings that go bad on 93 FDs and need to be replaced. Those were changed 10K ago by the previous owner.

Since WD-40 degrades rubber (long term), it's definitely not scientific.
Without predrilled Zerk fittings on the bushing carriers I still cannot understand how you can lube bushings on a car.
The differential bushings can also leak and (less commonly) the toe link bushings can become sloppy. A common source of noise is the anti-roll bar shifting and hitting off something.

The bar seemed secure and the left and right diff bushings appeared to be in similar shape.
Conclusion:
The right-rear-most exhaust hanger was not the right hanger. The correct hanger has a large rubber nub that firmly braces the hanger against the inside of the rear quarter panel. Without this proper anger the muffler has too much side to side slop and was banging on the inside of the quarter panel.
