How do you break-in a new rear differential?

New Gear Break-In Procedure

1. After light use for the first 15-20 miles, stop and let the differential cool before proceeding any further. Repeat this process two or three times.
2. Avoid heavy acceleration and don’t do any towing during the first 500 miles.
3. We highly recommend changing the oil after the first 500 miles.

What should the back lash be for pinion gear?

12. Once the pinion gear is installed, position ring gear and carrier into housing to check backlash. Motive Gear and Motive Gear Performance ring gear and pinions are developed to be run at .008″ to .012″ back-lash for street gear sets.

What’s the proper ring and pinion gear break in procedure?

Ring & Pinion Gear Break-In Procedure ALL new ring & pinion gear sets must be properly broken in to prevent damage & premature failure. Improper gear break-in procedures may cause overloading and overheating of the ring and pinion gears as well as break down of the gear oil.

Where do you put the ring and pinion housing?

Adjustments for backlash is done by spanner rings in the housing or shim packs behind the carrier bearing cups (GM) or cones (Dana). Always be sure carrier bearings are preloaded. The carrier should not fall out of the housing, but should have to be “tapped” in during final installation.

When to change the gear oil in a ring and pinion?

Maintaining a speed below 60 mph and driving conservatively for the first 100 miles is also advised. The gear oil should be changed after 500 miles. We recommend that you drive at least 500 miles before any heavy use or towing. During the first 45 miles of actual towing, only drive 10-15 miles at a time before stopping to let the differential cool.
