Removal & Installation



Land Cruiser
  1. Before servicing the vehicle, refer to the Precautions section.
  2.  
  3. Remove or disconnect the following:

    Driveshaft
     
    Rear wheels
     
    Rear brake calipers
     

  4.  


NOTE
The rear brake calipers must be removed so that there is no additional drag when measuring pinion bearing preload.

  1. Use an inch lb. torque wrench and measure the amount of torque required to maintain pinion rotation through several revolutions.
  2.  
  3. Remove or disconnect the following:

    Pinion flange
     
    Oil seal
     
    Oil slinger
     
    Pinion bearing and race
     
    Collapsible spacer
     

  4.  

To install:


NOTE
Use a new collapsible spacer and flange nut for assembly.

  1. Install or connect the following:

    Collapsible spacer
     
    Pinion bearing and race
     
    Pinion seal
     
    Pinion flange. Tighten the nut to 181 ft. lbs. (245 Nm).
     

  2.  
  3. Rotate the pinion flange occasionally while tightening the flange nut to make sure the pinion bearings seat correctly.
  4.  
  5. Take frequent bearing preload torque readings. Tighten the flange nut to achieve the preload torque readings originally recorded. Do not exceed 326 ft. lbs. (441 Nm) torque when tightening the pinion flange nut.
  6.  


CAUTION
Never loosen the pinion nut to reduce bearing preload. If it is necessary to reduce bearing preload, install a new collapsible spacer and pinion nut.

  1. Install or connect the following:

    Rear brake calipers
     
    Rear wheels
     
    Driveshaft. Tighten the fasteners to 78 ft. lbs. (106 Nm).
     

  2.  
  3. Fill the differential with gear lubricant and check for leaks.
  4.  

  1. Before servicing the vehicle, refer to the Precautions section.

  1. Before servicing the vehicle, refer to the Precautions section.
  2.  
  3. Drain the differential housing oil.
  4.  
  5. Remove the rear driveshaft.
  6.  
  7. Remove the companion flange, as follows:

    Loosen the staked part of the nut, using a chisel and a hammer
     
    Companion flange nut, using tool 09330-00021
     
    Companion flange, using tools 09950-30011 and 09954-03010
     
    Oil seal, using tool 09308-10010
     

  8.  

To install:

  1. Install the new oil seal until it is flush with the housing, using a plastic hammer and tools 09316-12010 and 09649-17010
  2.  


NOTE
Use vinyl tape to connect both oil seal installation tools.

  1. Install the companion flange, as follows:

    Companion flange
