Luckily you were able to diagnose the problem on your own otherwise they could've jacked you up big time on the bill for things that weren't needed..I walked around the car and in 10 seconds could see the drivers' rear wheel was toed out...it was obvious!
I went down into the pit and showed the guy the rear control arm was bent from no one hitting anything hard enough to bend the control arm.
To their credit, they replaced the control arm and aligned it for way less than any other shop.
I carry a star lug wrench in each of my vehicles, they help a lot. I have also slipped a hydraulic jack handle tube over the end of a short OEM lug wrench to give me more leverage.I hope the new owners know enough about wrenching to train their installers not to over torque the lug nuts - stranding their under gunned customers out in the middle of nowhere.
