: Problems with rear wheel alignment on 2006 STS 6 cyl rwd

I had all 4 wheels aligned at the time I replaced the tires 24 months ago. 17 months later I had another alignment before I took a long trip. 5 months later I noticed unusual wear on the the rear tires, especially the right rear. The garage showed me that all 4 wheels were out of alignment once again, especially the rear and especially the right rear. Now, 2 months later the right rear is noticeably out of alignment. I have not been driving on bad roads or hitting pot holes. Is it likely that the alignment adjustment mechanism on the rear wheels is worn and needs to be replaced? I have had no alignment problems for the life of the car going on 7 years and 74K miles.

More likely bad lower control arms and/or shocks.
