    One in a million but I know it happened once. Truck was parked after running without a good oil supply in the steer axle bearings. When they cooled overnight they welded themselves and locked up tight. Would not turn.

    The brake pedal...does it feel any different? When you step on the brakes, does the pedal move, or is it extremely stiff?

    If YES, lift up your brake pedal, and you should feel what feels like a steel button covered by a dust boot. Lift the boot up and flood that button with PB Blaster. After about 10-15 minutes, take a big pair of channel locks, grab that button and try turning it side to side. It will pop out and your brakes should release.

    This happened to my truck a couple weeks ago I got it unstuck but do you suggest I replace anything? I haven't hit the road with it since as I'm still waiting to put it on somewhere and saving money

    Wow, so much .... and really nothing


    Cage each brake set to see if they are the problem, you don’t need to so much other than see if the shoes are “welded” to the drums.

    I never replaced anything. The PB Blaster bath lasted a couple years.
