    REMOVAL & INSTALLATION



    1. Disconnect the negative battery cable.
    2.  
    3. Disconnect the driveshaft from the differential companion flange. Refer to the appropriate procedure in this section.
    4.  
    5. Using a hammer and chisel, loosen the staked part of the companion flange nut. Use SST 09330-00021 or an equivalent flange securing bar to hold the flange while removing the nut and washer. Remove the companion flange.
    6.  
    7. Using SST 09308-10010 or an equivalent seal puller, remove the oil seal from the housing.
    8.  
    9. Using SST 09556-12010 or an equivalent bearing puller, remove the front bearing from the drive pinion. Remove the bearing spacer.
    10.  

    The bearing must be removed in order to replace the bearing spacer. This is done since proper bearing preload is lost when the companion flange nut is loosened. It is imperative for proper bearing preload to be achieved.

    To install:
    1. Slide a new bearing spacer and bearing onto the pinion shaft.
    2.  
    3. Install the oil slinger and a new seal. Using SST 09554-30011 or an equivalent seal driver, drive the seal to a depth of 0.039 in. (1mm). Apply some multi-purpose grease to the oil seal lip.
    4.  
    5. Using SST 09557-22022 or an equivalent puller, install the companion flange.
    6.  
    7. Use SST 09330-00021 or an equivalent flange securing bar to hold the flange. Install the washer, then coat the threads with multi-purpose grease. Tighten the nut to 103 ft. lbs. (140 Nm).
    8.  
    9. Using a beam-type torque wrench, measure the bearing preload. Smoothly rotate the wrench and record an average reading. Do not record the break-away torque (the amount of force necessary to start the assembly moving) as it is not indicative of true preload. It should be between 5.6-10.9 inch lbs. (0.6-1.2 Nm).
    10.  
    11. If preload exceeds specification, replace the bearing spacer and repeat the preload procedure. Do not back off the pinion nut to reduce preload. If preload is less than specification, retighten the nut in 9 ft. lbs. (13 Nm) steps until the specified preload is reached. Do not exceed 174 ft. lbs. (235 Nm). If this maximum torque is exceeded, replace the bearing spacer and repeat the preload procedure.
    12.  
    13. Stake the nut, then connect the driveshaft to the companion flange.
    14.  
    15. Check the fluid level, add if necessary.
    16.  
    17. Road test and check for proper operation.
    18.
