the rear axle needs adjustment, tires are lean outward, on 2001 BMW X5

what is the name of the part that will adjust the wheels to proper alignment. How much should it cost to do, and what is the name of the part that needs to be adjusted. Someone says it is the Camer, but they did not know how to spell it. They said only BMW dealers can do that true! They also said it does not take long to do?

IF the CAMBER is adjustable from the factory , then any properly equipped alignment shop (NOT chain store type!), should be able to handle it. IF the camber is not adjustable , then yes you may want to bring it to the dealer , so it's done right , the first time (a theory some shops still work with).
Thank you Zipple! Have a wonderful day!
