Ford 9-Inch Rear Axle - Drivetrain Tech: Number Nine

If You're Adding Big Power To Your Vintage Mustang, It May Be Time To Switch To A 9-Inch RearendSooner or later, it boils down to what direction you're going to go when your Mustang's rear axle wears out. Some decisions are straightforward. If you have a six-cylinder Mustang, stick with the factory 7 3/4-inch integral carrier rear end. Perform a rebuild with fresh bearings and seals, plus a ring and pinion if needed, and you're good to go for another 100,000 miles or more. If you're running a stock or mild small-block, all you need is the 8-inch removable carrier rear axle that your Mustang came with. Again, fresh bearings, seals, and cogs and you're ready to ride. Depending on wear and noise, sometimes you can get away with reusing the gears.
