Leaks

Most minor weld leaks can be corrected with Devcon Aluminum Liquid F2 or equivalent meeting Ford Manufacturing Standard M-3D35A(E). This includes the "puddle" or fill welds that join the axle shaft tube to the rear axle housing on integral axles.

Fill welds sometimes leak and can be sealed easily. If a weld is broken, the rear axle housing must be replaced. Rear axle housing straightness is too critical for field repair.
