Well, after I installed an adjustable rear upper control arm and adjusted it to fix the extreme camber problem a year ago, I was working on the rear sway bar and excessive squeaks. I discovered that the main lower control arm (the one that the sway bar attaches to), is adjustable for rear camber. All you have to do is loosen the nut on the interior pivot bolt slightly, and then turn the bolt. This swings the bottom of the tire in or out. There is a lot of adjustment here and it is very easy to do. So anyone that wants to reduce the rear camber (-2.7 degrees from factory), just needs to pull the bottom of the tire in some. For the past year I have been at -1.3 degrees and it works fine. And tire wear is perfectly even all the way access. So, even if you take it to an alignment place, they may not know that this bolt adjusts the camber.

 

Good share! Not all alignment shops are aware of the features of all cars. One of my maintenance "investment" strategies is to periodically get a dealer alignment to baseline the car, particularly after any major suspension work.I then let my local indy to do the in between scheduled alignments.

 

There is no camber adjustment. Just toe. Which bolt?

 

After another look, you are absolutely right. My mistake. I am sorry guys. The bolt only swings the REAR of the tire in & out. The front is held in place by the control arm.

 

A few good answers posted. I always take my Volvos to independent Volvo shops with excellent results, cheaper labor but genuine Volvo parts or from excellent parts suppliers. Always asks for authorization to complete repairs after cost estimates and gives 1 or 2 levels of repair with estimates if possible.
