The front bolts are 18mm and tq 52ft/lbs. The rear bolts are 15mm and tq to 76ft/lbs. The differental housing cover bolts are 13mm and are tqed to 24 ft/lbs.

If refilling the rear axle (4001), first add 118 ml (4 oz) of Additive Friction Modifier C8AZ-19B546-A or equivalent meeting Ford specification EST-M2C118-A.
