Setting up the carrier
Gear sets on an 8.2 inch Toyota axle are set up at the carrier, so the work depends on how the carrier is built and how the pinion depth is established. Before ordering, check the carrier bearings, pinion bearing and crush sleeve condition, since those parts are usually disturbed during a gear swap.
Fresh gear oil and a brief break-in period help the new gears seat. After the first few drives, inspect the gear oil for metal particles and recheck bolt torque on the carrier caps. Tooth contact patterns that run too close to one edge point to a setup issue that should be corrected before regular use.
- Replace the pinion crush sleeve during setup
- Inspect carrier bearings for pitting or play
- Use gear oil with the friction additive your axle needs
- Recheck carrier cap bolt torque after break-in
