Binding whene backing

[leegreen]

This is 2wd right? So no front drive axle issues to worry about.

Does it release as soon as you pull forward or straighten out in reverse?

Brakes binding in reverse: I'd check rear drum brakes are assembled properly, particularly the return spring, ebrake rod and hold down spring on the rear shoe and make sure the shoes can slide back and forth across the backing plate without getting hung up in a groove worn into the shoe support pads

Brakes binding only when you turn implies wheel bearings, tire rub, end play in axle shafts or a differential locking issue

binding only in reverse when turning....maybe two problems
