I have an 03 P stroke with 170K on it, when turning left or right at low speeds. It has a shake to it like the rear end axle bearings or u joints. No unusual noises like a u joint squeak. Could it be a brake caliper hanging up. Anyone had this issue or heard of such.

 

Check to make sure your front hubs are unlocked, or it will feel like you're in 4wd
