Ford Mustang (1999-2004) Service Manual: Axle Housing Casting Porosity (Holes in Casting) Repair
CAUTION: To keep the axle's sound characteristics, do not disassemble the carrier.
NOTE: Casting porosity is a condition where occasionally gas bubbles will form during the casting process leaving small pockets in the metal that will cause the axle housing to leak.
1. To fill small pockets, peen in a small amount of body lead.

2. Seal the pocket.
- Use epoxy sealer meeting Ford specification M-3D35A(E).
3. To fill large pockets, drill and tap a shallow hole for a small setscrew. Install the setscrew and seal it.
- Use epoxy sealer meeting Ford specification M-3D35A(E).
