REMOVAL
NOTE:The pinion seal can be replaced without removing the rear axle assembly from the vehicle.
1. Raise the vehicle on a hoist or raise the rear end of the vehicle with a jack. Install safety stands under the frame rails and lower the jack or hoist far
enough to allow the rear axle to drop into the rebound position for working clearance.
2. Remove the nuts and two U-bolts (Models 60 and 70) or four bolts (Model 80) from the rear axle universal joint flange and disconnect the
driveshaft. Wire the driveshaft to the frame.
NOTE:Note and mark driveshaft/rear axle universal joint flange position so that it can be reassembled in the same position to minimize driveline
vibration.
3. Using a suitable companion flange holding tool to hold the rear axle universal joint flange, remove the drive pinion shaft nut.
4. Using the (A) 2-Jaw Puller, remove the (B) rear axle universal joint flange.
