Rear wheels lean out m

Wheels leaning in or having negative camber is fairly normal with a modern car as it improves the cornering capability immensely - the big question; is the amount of negative camber right for your car or has it become excessive due to wear or damage or unwise modification.
Clearly, as you have noticed it, someone qualified should carry out a safety inspection and an alignment check...

Ok I think your spindle bushings in the rear are broken the squealing is from the tire rubbing against either the strut or rear control arm with the car on the ground look at the wheel to see if it A ) is leaning in on top from the rear of the vehicle B) turning inwards from either the front or the back the spindle has a front/rear bushing on it C) or the rear control arms have a bad bushing or are bent did you hit anything or drive off a curb or slide into an object in the rain like a curb then this is it look at the tire for wear marks it will point you to the possible contact points D) the rear wheel bearing/hub may be loose or shot causing the wheel to lean inwards E )the rear strut on that side has failed making the body dip down as well as the stabilizer link and the tire is contacting the spring seat or the inner fender F) also there is rear wheel alignment settings that are out from all described above but if you drive normal and it has stock tires on it then it's a bushing or arm that's doing it you must go to the rear and feel for excessive heat on the tires so you know which or both wheels to check

possible but if you overloaded the unit I would be checking for a broken axle . Jack up the vehicle and turn the tail shaft to see there are any violent noises indicating a pinion gear/ crown wheel gear failure. remove drain plug to check for metal pieces on magnet

Wheel Bearing has nothing to do with suspension
damage or the need to have it adjusted or rear
alignment done

The first step is to put up on a lift and look for any bent arms, the most common reason for a leaning wheel is somthing is bent, compare to the otherside and see if any of the arms are bent, after replacing bad parts an alignment will be needed. good day.

No it doesn't, but something happened to your rear end. It must have too much weight in the trunk, or the bolts have come loose and let the rear end slip down, I know they can be brought back up, there are shims that slide in and out to get it aligned, but usually, they stay put because of the weight difference, I would take it to a different garage and have them look at it and make sure nobody messed with it. Then get it shimmed back up. A lot of cars come off the line like that, VW's, BMW's, How would like to pay $30,000 for a car with the rear wheels leaning in at the top? I wouldn't. Check it out, Hope this helps.

Had same problem with my Caddy POS . I took off left rear wheel and disconnected air line. Make sure you take fuse out of system in trunk behind back seat so that the problem doesn't occur again. Just let car ride on suspension. Should not be a problem as long as you don't overload trunk.

The best thing to do is to take it to a local Frame and Alignment Shop and have them put the vehicle on a Frame Machine and take measurements to determine what is exactly bent before throwing money on parts you might not need.

there can be a few things the control arms,bushings,bearings

AIR SUSPENSION BAG IS LEAKING AIR.
