Front Axle Assembly - M210
REMOVAL
- Raise and support the vehicle. Refer to HOISTING, STANDARD PROCEDURE .
- Position and secure a lift under the axle.
- Mark an installation reference line across the front driveshaft flange and the axle flange.
1 - Front Driveshaft Flange 2 - Front Axle Flange - Remove the front driveshaft to pinion flange bolts. Remove front driveshaft from front differential pinion and secure out of the way using a bungee or suitable strap. Refer to REMOVAL AND INSTALLATION
.CAUTION:
Driveshaft removal is a two-person operation. Never allow the driveshaft to hang from the center bearing, or while only connected to the transmission or rear axle flanges. An assistant is required. If a driveshaft segment is hung unsupported, damage may occur to the shaft, joint and center bearing from over-angulation. This may result in driveline vibrations or component failure.
- Disconnect the TRU-LOK wire harness connectors and axle vent hose.
- Remove the calipers and rotors from the axle. Refer to: FRONT, ROTOR, BRAKE, REMOVAL AND INSTALLATION .
- Remove the wheel speed sensors from the hub bearings. Refer to SENSOR, WHEEL SPEED, FRONT, REMOVAL AND INSTALLATION .

INSTALLATION
Follow the removal procedure in reverse for general reassembly of the components on the vehicle. The steps listed below are calling out specific procedures that should be followed during installation.
The weight of the vehicle must be supported by the springs before suspension arms and track bar fasteners can be tightened. Failure to follow these instruction will result in damaging the bushings.
- Loosely tighten the upper and lower control arm bolts until after the axle is installed and all other bolts are torqued. Torque the upper and lower control arm bolts last.
- Verify that the lower control arm cams are aligned to the reference marks before tightening to specification.
- Install the driveshaft with the axle flange and driveshaft marks aligned and tighten the NEW bolts to the proper torque specification.
