TOTAL PRELOAD

Using a spring scale, check the total preload.

Total preload

Except for GT spec. B 6MT model

20.7 - 54.4 N (2.1 -5.5 kgf, 4.7 - 12.2 lb)

GT spec. B 6MT model

27.0 - 54.0 N (2.8 - 5.5 kgf, 6.1 - 12.2 lb)

If the total preload is not within the specification, adjust the side bearing retainer shims.

  1. If rust or dirt is attached to the companion flange, remove them.
  2. Set a dial gauge at a companion flange surface (mating surface of propeller shaft and companion flange), and then measure the companion flange runout. Limit of runout: 0.08 mm (0.003 in)
  3. Set the gauge inside of the companion flange, and measure the runout. Limit of runout: 0.08 mm (0.003 in)
  4. If either runout exceeds the limit, move the phase of companion flange and drive pinion 90° each, and find the point where the runout is within the limit.
  5. If the runout exceeds the limit even after changing the phase, replace the companion flange and recheck the runout.
  6. If the runout exceeds the limit after replacing the companion flange, the drive pinion may be assembled incorrectly or bearing is faulty.

Adjust the side gear backlash.
