Thanks for your exhaustive reply. I do have brackets for neg. camber in rear....I'll try and have all that removed to see if
that helps (actually been thinking about this before). Brakes were done already. Don't know about knuckle joints..

Terry: still in Oakland, Montclair. Been into a lot of SAAB lately (heritage). 

Thanks all!

Spreading out the thought pattern:

Since you replaced the swing arms, bushings and all, and grease helps a bit, I'd suggest you check the swing arm shaft nuts are properly torqued/shimmed (not sure if they should be), if you have adjustable camber brackets that they are secure, that the handbrake cable quadrants are properly supported (not too loose), that the brake backing plates are properly secure, that the rear brakes are properly installed with the springs the right way round, that it isn't the exhaust system making contact on a bump...

Since you installed steel coil springs, you probably have adjustable trumpets. If you've set the ride height too low, you may be getting slack in the suspension when the wheel drops. The springs should have at least a little compression from the swing arm with the wheel on full droop while jacked up.

You said you also replaced the shocks. Are they the right length for your suspensions set-up? Are you certain they are properly tightened?

Pers:
I am assuming the knuckle joints were checked or replaced when the arms were replaced.
I have one cars that seems to have a similar rattle, but it is intermittent.
Still in Oakland/Claremont?

I had my mechanic do it...
I bought the kit, NAM7163KIT that includes bushes.
But I never have anything done to subframe bushings.

Thanks

Persimon,

jack the car up, grab the upper and the lower part of the wheel and wiggle it just a little bit,  observe if it wiggles even a tiny bit, i suspect its either loose rear axle bearing castle nut or worn out bearing.  If its a worn out bearing stop driving your car until you have replaced it for safety purposes. 

Note: make sure that you are jacking the car on the correct jacking points.  Common sense is free, use it...  Good luck!!

Jack it up and check the swing arm bushings for wear. By you greasing the swing arms and the noise almost going away that should be where the wear is.
Just re read this. Why and how would you replace the arms and not the bushings ?

If in doubt, flat out . Colin Mc Rae MBE 1968-2007.

Its an MPI and over cracked road there is clunky noise or rattle from the rear. Noticeable mostly over sharp edges/cracks in the road.
No noise over smooth bumps.

I've replaced shocks, rubber springs (to coil spring), even replaced to new swing arms and still this clatter. I have not done any
bushings. Almost out of hope of ever getting rid of it. Whenever I grease up the swing arms the rattle is almost gone which is why
I was sure it as the swing arms..But over washboard type roads it is worst, both sides but mostly driver side. It sounds as it comes from the
swing arm area.

Any suggestions...?
Thanks
