My 55 M38A1 has a rear axle issue. The axle shaft on the rear drivers side has come lose and slipped out. It did not come out completely before I caught it so no damage was done. The wheel bearing has failed but I don't know if that was a result of the axle coming lose or if the axle is lose because the wheel bearing failed. Would a bad wheel bearing allow the axle to slide out or has something else come lose to allow that to happen? Thanks
