When replacing the bearings, the mechanic recommended to align the rear end assembly. According to him, the tires were inclined inwards on the upper part. Shouldn't they be like this or do they have to be aligned? I was told it was a normal position and that it allows a better stability. In case it has something to do, I replaced the torsion bars. Could you please help me? I would like to know which measurements need to be made as well. Thanks.
The rear wheels have a negative camber angle so that a better grip is achieved and so that it does not turn more than necessary. The torsion bars do not need to be replaced unless one of them is cut. The rear height is regulable, so I recommend you to take your car to a specialist in suspensions.
