So I just got 4 new tires but I can't get my poorly aligned tires aligned. My rear suspention is nearly shot. My control arms are all good, but the 3 other bars that link up to it are shot, the bushings are rusting and my wheels are loose (you can shake them horazantaly). I got a picture from another Post, i couldn't find out what there called... Could someone identify these parts...Exclude the control arms in the picture, i think two are Thrust Arms, but im not too familar with the rear suspention components. Also in this a DIY job, i got money for the parts, but not the 100+/hour for labor.

Ohh, can i just replace the bushings??? or do i have to replace all the bars

thanks
