Is it a crunch sound that is most likely to occur when going from reverse to forward?

A common cause is loose rear spindles in the rear wheel bearings. The splines are a loose fit. The clamping action from the nut keeps the spindle from rocking in the bearing splines. It's easy to eliminate this possibility. Just remove the rear tires and tighten the nuts. The torque specification is 164 lb. ft. I like to tighten them about 10% tighter to 180 lb. ft.
