DRIVE SHAFT ASSEMBLY
REMOVAL AND INSTALLATION
CAUTION:
^ For vehicles with ABS, do not strike the ABS rotors installed to the BJ outer race of drive shaft against other parts when removing or installing the drive shaft. Otherwise the ABS rotors will be damaged.
^ For vehicles with ABS, be careful not to strike the pole piece at the tip of the rear wheel speed sensor with tools during servicing work.
REMOVAL SERVICE POINTS
<> DRIVE SHAFT NUT REMOVAL
CAUTION: Do not apply pressure to wheel bearing by the vehicle weight to avoid possible damage to wheel bearing before tightening drive shaft nut fully.
Use special tool MB990767 to fix the hub and remove the drive shaft nut.
<> DRIVE SHAFT REMOVAL
1. Use special tools MB990242, MB990244, MB991354 and MB990767 to push out the drive shaft from the hub.
CAUTION:
^ Do not pull on the drive shaft; doing so will damage the TJ; be sure to use the pry bar.
^ When pulling the drive shaft out from the differential carrier, be careful that the spline part of the drive shaft does not damage the oil seal.
2. Remove the drive shaft from the differential carrier by using a pry bar.
CAUTION: Do not apply pressure to the wheel bearing by the vehicle weight to avoid possible damage when the drive shaft is removed. If, however, vehicle weight must be applied to the bearing in moving the vehicle, temporarily secure the wheel bearing by using the special tools MB991000 and MB991017.
