Overview
The Dana Spicer Dana 44 Rear AdvanTEK 4.56 Ring and Pinion, part 10067141, is a rear gear set for the Dana 44 AdvanTEK axle with a 4.56 ratio.
Dana Spicer says its ring and pinion gears are designed and tested to original equipment specifications, and that genuine Spicer sets meet or exceed the Dana standards that OEMs have relied on.
Key features
- 4.56 gear ratio
- Rear axle position
- Designed and tested to original equipment specifications
Setup and break-in planning
A ring and pinion is only as good as its setup. Pinion depth, bearing preload and backlash all have to be set before the carrier is closed, and small errors show up as whine or early tooth wear. Setup takes patience and a good set of dial indicators, plus a clean housing and bearings.
Break-in matters for new gears. Driving gently for the first several hundred miles lets the tooth surfaces settle, and a re-check of tooth contact afterward confirms that the pattern is right. Changing the ratio also changes the speedometer reading, so plan for that when you finish the install. Keep the old carrier bearings in mind, since many installers replace them together with the gear set.
- Set pinion depth before preload
- Check tooth contact after break-in
- Plan for speedometer calibration after a ratio change
