Mopar 68140297AA Rear Axle Shaft

You can Select Your Vehicle to check if 68140297AA fits your vehicle.

To prevent damage to the outer CV joint, you should suspend the drive axle with wire.

In a semi-floating design, the axle supports the weight of the vehicle on the axleshaft and transmits driving forces to the rear wheels.

Remove any remaining interfering wiring harness clips. Remove the axle assembly pinion mounting bolts.

The axleshaft should be carefully pulled from the axle housing.

For a full-floating axleshaft, loosen the rear wheel lug nuts, raise the rear of the vehicle, and support it securely on jack stands. Remove the wheel and axleshaft flange bolts.

Raise the rear of the vehicle and support it with jack stands placed under the frame rails. Remove the rear wheels. Disconnect the driveshaft from the rear axle. For leaf spring models, disconnect the ABS sensor(s). Disconnect the parking brake cable from the parking brake lever. Unscrew the vent hose fitting to detach the brake line junction block from the axle tube. Disconnect the brake lines from the clips and brackets on the axle housing. Remove the rear brake calipers. Tie the calipers up with wire to keep any stress off the flexible brake lines. Support the rear axle with a floor jack. If the rear differential is offset to one side, you'll have to use two jacks - one placed under each axle tube. Remove the lower mounting bolts securing the rear shocks to the axle. With the jack(s) supporting the axle, remove the nuts and U-bolts securing the axle to the springs. Lower the axle assembly and remove it from under the vehicle. For coil spring models, disconnect the wiring from the rear wheel speed sensors, then unbolt the sensors and remove them. Remove the mounting bolts from the rear brake calipers and hang them out of the way using wire. Take care to avoid putting tension on the brake hoses. Disconnect the vent hose from the axle tube. Disconnect the parking brake cables from the rear brake assemblies. Detach the parking brake cable clamps, then move the cable clear of the rear axle. Remove the bolts from the stabilizer bar clamps. Support the bar with wire. Support the center of the axle with a floor jack. Raise the axle enough to avoid fully extending the shock absorbers. Remove the bolts from the lower shock absorber mounts. Unbolt the track bar from the rear axle and secure it out of the way. Remove the bolts that secure the four control arms to the rear axle. Discard all suspension mounting bolts. They should be replaced with new ones. With the help of an assistant, slowly lower the rear axle until the coil springs can be removed. Fully lower the axle and remove it from under the vehicle. Installation is the reverse of removal. Tighten all fasteners to the torques. Tighten the caliper mounting bolts to the torque. If necessary, check and fill the axle with the specified lubricant.
