REMOVAL & INSTALLATION
See Figures 1, 2, 3, 4 and 5
There is no provision for axle shaft end-play adjustment on these axles.
- Jack up the vehicle and remove the rear wheels.
- Clean all dirt from the housing cover and remove the housing cover to drain the lubricant.
- Remove the brake drum.
- Rotate the differential case until the differential pinion shaft lockscrew can be removed. Remove the lockscrew and pinion shaft.
- Push the axle shafts toward the center of the vehicle and remove the C-locks from the grooves on the axle shafts.
- Pull the axle shafts from the housing, being careful not to damage the bearing which remains in the housing.
- Inspect the axle shaft bearings and replace any doubtful parts. Whenever the axle shaft is replaced, the bearings should also be replaced.
- Remove the axle shaft seal from the bore in the housing using the button end of the axle shaft, or a suitable removal tool.
- Remove the axle shaft bearing from the housing. On standard axles, use a slide hammer and adapter. On the 9 1 / 4 in. HD axle, use a puller such as C-4828, or its equivalent. Do not reuse the bearing or the seal.
- Check the bearing shoulder in the axle housing for imperfections. These should be corrected with a file.
- Clean the axle shaft bearing cavity.
- Grease and install the axle shaft bearing in the cavity. An installer tool is recommended, although a drive can be used. Be sure that the bearing is not cocked and that it is seated firmly against the shoulder.
- Install the axle shaft bearing seal. It should be seated beyond the end of the flange face.
- Insert the axle shaft, making sure that the splines do not damage the seal. Be sure that the splines are properly engaged with the differential side gear splines.
- Install the C-locks in the grooves on the axle shafts. Pull the shafts outward so that the C-locks seat in the counterbore of the differential side gears.
- Install the differential pinion shaft through the case and pinions. Install the lockscrew and secure it in position.
- Clean the housing and gasket surfaces. Install the cover and a new gasket. Refill the axle with the specified lubricant.
Replacement differential cover gaskets may not be available. The use of gel type non-sticking sealant is recommended.Model 60 and 70
- Remove the axle shaft flange locknuts and washers, or bolts.
- On axles with locknuts, rap the axle shafts sharply in the center of the flange with a hammer to free the dowels.
- Remove the tapered dowels and/or axle shafts.
- Clean the gasket area with solvent and install a new flange gasket.
- Install the axle shaft in to the housing.
- If the axle has an outer wheel bearing seal, install new gaskets on each side of the seal mounting flange.
- Install the tapered dowels, lockwashers, and nuts or Durlock® bolts. Tighten the 7 / 16 - 20 nuts to 40-70 ft. lbs. (54-95 Nm); the 1 / 2 - 20 nuts to 65-105 ft. lbs. (88-143 Nm); the Durlock® bolt to 60 ft. lbs. (82 Nm).
