Well, I am not 100% thrilled with the clarity of advice concerning this topic, and have pretty well searched the site. The FAQ section seems a bit vague when it comes to terminology. There has to be a clear distinction between trailing arm bushings (TABs), torque arm bushings and Panhard rod bushings. Realize that most of "us" have moved on from the 200/700 series, however, believe there are still enough die-hard RWD owners. My car problem appeared when I started hearing and feeling a "rumble" from the rear whenever gently starting from a dead stop, and for maybe two seconds got this effect and again when gently braking back to a stop. Using my imagination, 50 years experience with cars and other machinery, came to the conclusion that the driveshaft u-joint connected at the differential was getting abnormally misaligned, due to axial rotation of the rear axle case when subjected to braking or driving reactions from the wheels. In other words, there's a torque caused by linear road force at the tread multiplied by the tire radius. The main resistance against this force would seem to be the torque rods, which form a kind of "trapezoid" when linked to the subframe points and lugs on the axle housing near the diff case. Any looseness here would cause the axle to wobble and telegraph the vibration to the Panhard rod and car body. Another possibility would be very loose trailing arm bushings, which would cause the axle assembly to shift fore and aft, under the conditions previously stated. I tried rocking the car by hand with handbrake on to look for movement of the axle. Any suggestions are welcome.
