Weld Leaks Repair
1. CAUTION: To keep the axle's sound characteristics, do not disassemble the carrier.CAUTION: Rear axle housing straightness is too critical for field repair. Install a new axle housing if a weld is broken.
NOTE: Most minor weld leaks are repairable. This includes the puddle and fill welds that join the axle shaft tube to the axle housing on integral axles.
Seal the weld.
