Safely raise and support the vehicle, try to move tires, up and down, sideways, in and out. If you get much movement, check where movement is coming from. Check your brakes.

Just to add, I did see a service bulletin, applies to 4wd--awd--control trac. Shudder or binding in slow speed turns. Check air pressure in tires. Measure the circumference of the two front tires, if more than 1/2 inch difference between tires, replace the smaller tire. Same thing on the rear.
