What causes rear end to wander?

[Free2drive!]

Problem, car wanders at speed and seems to turn more left more tightly than turning right.

I replaced the front control arms and drop links, the front struts were done last year!

Alignment was done 1 month ago they said it squares up on thier rig but something on the rear axle/suspension might be worn??

Question, what could cause wandering on the rear end?
Car is 94 t5 auto 143k miles.

There are a couple of possibilities on the rear. The bushings that tie the trailing arms together or the end links where the trailing arms mount to the frame (chassis). When the bushings go bad they normally really go bad and separate. When the end links go bad they normally clunk on small bumps.

Either one can be diagnosed visually if you jack up the back of the car.

Thanks, are any of these easy to replace?

The endlinks can be a bear unless you just melt them out with a torch. I have not had to replace any of the bushings yet so I have no hands on experience. Others that have changed them indicated that it was pretty easy.

It took me a while to figure out that the torch was the way to go.

I have had the loose rear end symptoms from tires being aged. They had good tread, and held air but at speed the car felt like the tail wagging the dog! When it first happened I was sure something had come undone. Yet there was no sign of worn bushings, loose mounts etc.
Rotate and see if the behavior changes.
Make sure the easy things are right before you do something more time and money consuming.
