Installation Of Differential Case

2003 Nissan-Datsun Frontier Base, StandardSECTION Installation Of Differential Case
  1. Install differential case assembly with side bearing outer races into gear carrier.
  2. Position side bearing adjusters on gear carrier with threads properly engaged; using Tool, screw in adjusters lightly at this stage of assembly.
    1. Tool number: ST32580000 (J-34312)

    • Do not tighten at this point. This allows further tightening of side bearing adjusters.
  4. Tighten both right and left side bearing adjusters alternately and measure ring gear backlash and total preload at the same time. Adjust right and left side bearing adjusters by tightening them alternately so that proper ring gear backlash and total preload can be obtained.
    1. Ring gear-to-drive pinion backlash: 0.13 - 0.18 mm (0.0051 - 0.0071 in)

    • When checking preload, turn drive pinion in both directions several times to set bearing rollers using Tool. 
      1. Tool number: ST3127S000 (J-25765-A) 
      2. Total preload: 1.7 - 2.5 N.m (17 - 25 kg-cm, 15 - 22 in-lb)

  5. Tighten side bearing cap bolts.
    1. Side bearing cap bolts: Refer to " COMPONENTS  ". 
  6. Install side lock finger in place to prevent rotation during operation.

  7. Check runout of ring gear with a dial indicator.
    1. Ring gear runout limit: 0.08 mm (0.0031 in)

    • If backlash varies excessively in different places, the variance may have resulted from foreign matter caught between the ring gear and the differential case.
    • If the backlash varies greatly when the runout of the ring gear is within a specified range, the hypoid gear set or differential case should be replaced.
  8. Check tooth contact. Refer to "TOOTH CONTACT ".
