Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Total Preload Torque
- Measure pinion bearing preload torque (P1). Refer to
"PINION BEARING PRELOAD TORQUE ".
Pinion bearing preload torque (P1)
: 0.10 - 0.39 N.m (0.01 - 0.04 kg-m, 1 - 3 in-lb)
- Install the pinion sleeve shims and pinion sleeve assembly.
- Rotate the companion flange at least 20 times to check for smooth operation of the bearing.
- Using a preload gauge, measure the Total preload torque.
Tool number: ST3127S000 (J25765-A)
Total preload torque
When all oil seals are installed
: P1 + 0.16 - 0.22 N.m (0.016 - 0.023 kg-m, 1.4 - 1.9 in-lb)
Without transfer case oil seal and adapter case oil seal
: P1 + 0.06 - 0.12 N.m (0.006 - 0.013 kg-m, 0.6 - 1.1 in-lb)
- If measured value is out of the specification, disassemble it to check and adjust each part. If measuring the Total preload torque after the disassembly, measure it with the transfer case oil seals and gear ring oil seals removed, then install the oil seals.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
