GENERAL PROCEDURES
Axle Housing 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.
Use Devcon Aluminum Liquid F2 or equivalent meeting Ford specification M-3D35A(E).
