Still with unstable rear suspension after mild lift!!!

[CharliePR74]

Hey guys. Put a thread sometime ago regarding my runner's suspension (too harsh). Was able to get rid of the harshness by doing a combination between KYB shocks and OME coils. I did a mild lift only to avoid the usual bump stops contact and it worked, but now the rear suspension feels very unstable, the runner is shaking it's butt all around the road. When going over bump stops, you can feel it moving to one side; like the rear differential is not centered. I took some measurements and it still seems to be in the center, although the panhard is not horizontal anymore. I have been advice to replace all of the rear differential links bushings to start eliminating variables, and then if necessary, get an adjustable panhard to align the differential as that should be the last resource to fix of the problem. Just checked the panhard bushings and they are ok. I took my runner for alignment after replacing all coils and the guy at the alignment shop told me he didn't identified any misalignment on the rear suspension (still doubt it). Shocks are fine, not leaking oil, tires are new and balanced and coils are OME 2880 (front) and 2906 (rear).

Will remove the links tomorrow to inspect all bushings and replace if necessary. About 205,000 miles on the odometer .

Please advice!
