Stuck differential cross pin bolt won't come out
The bolt head presses directly against the differential housing, leaving no room to slide out without risking snapping the end. High-torque tools like impact wrenches and 4-foot breaker bars fail to break it loose, often resulting in broken tools or the fear of shearing the bolt entirely.
