Axle Housing Weld Leaks Repair

WARNING: This page is about a different car, the 2003 Mercury Marauder, 2003 Mercury Grand Marquis, and 2003 Ford Crown Victoria. However, it is still accessible from the selected car via links, so may be relevant.

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 meeting Ford specification M-3D35A(E).
