After Towing

1. Remove the covers from the hubs.
2. Install the gasket or O-ring, and axle shaft into the axle housing and carrier in the same location it was
removed from. The gasket and flange of the axle shaft must be flat against the hub. Rotate the axle
shaft and/or the driveline as necessary to align the splines and the holes in the flange with the studs
or holes in the hub.
3. Meritor axle only: Install the dowels over each stud and into the tapered holes of the flange.
4. Install the washers and stud nuts or cap screws.

type and amount of lubricant if necessary.
CAUTION
Make sure axle shafts or driveshaft are installed correctly after towing. Tighten axle shaft and driveshaft
nuts to the correct torque settings. Do not invert shafts.

TOWING FROM THE FRONT

The towed vehicle must be lifted from the front with front wheels off the ground. The tow truck must be
equipped with the proper lifting equipment i.e. tow bar, axle forks and holders to reach under the front
axle or the front tow eye pads. No other lifting points are recommended for towing.
Lifting and towing from any other point is not authorized as it may cause structural damage. To prevent
overloading the drive axle, do not unload or raise the tag axle when towing the vehicle.
To prevent damage to the vehicle, use the front tow eye pads fixed to the vehicle chassis between the
front axle and the front bumper. Only use a solid link tow bar and safety chains to tow the vehicle.
1. Block the wheels to prevent the vehicle from moving.
2. Perform the PREPARATION BEFORE TOWING. Refer to paragraph 2.1.
3. Disconnect both drive axle shafts to prevent damage to the transmission. Plug axle tubes to prevent
oil loss. Refer to 2.1.3
