Welds/Seams

Most minor weld leaks can be corrected with Devcon Aluminum Liquid F2 or equivalent meeting Ford manufacturing standard M3D35-A(E). This includes the puddle or fill welds that join the axle shaft tube to the rear axle housing on integral axles. They sometimes leak and can be sealed easily. If a weld is broken, the rear axle housing must be replaced. The alignment is too critical for field service.
