When working on the differential it's important to understand that it's far more than just replacing the part. If the pinion gear is not matched and properly adjusted to the ring gear, the differential will howl and fail prematurely. The process is not something that can be easily described, you really do need to have someone show you how.
You change the ring and pinion gears
The 2010 Camaro SS has an 8.6 ring gear with a 2 pinion positraction unit in the middle section.
Is it an automatic? If so, you may need to change the transmission filter and fluid.
A crown and pinion gear system consists of two gears: the pinion, which is a small gear, and the crown gear, typically a larger, circular gear with teeth angled perpendicular to those of the pinion. The pinion gear engages with the crown gear, allowing for a change in direction of motion, commonly seen in applications like vehicle differentials. As the pinion rotates, it drives the crown gear, converting rotational motion into lateral motion. This setup is crucial for transferring torque efficiently while enabling smooth changes in direction.
count your teeth on your ring gear <big gear> and on you pinion <little gear> and the divide the ring gear teeth by the pinion
41 teeth on the ring gear, 10 on the pinion gear.
43 ring gear 14 pinion
pinion is a gear with a small number of teeth designed to mesh with a larger gear. {m@Gn3T0}

A pinion gear rotates when it is driven by another gear or motor. As the driving gear turns, its teeth engage with the teeth of the pinion gear, causing it to turn in a specific direction. The rotation of the pinion gear can then transfer motion to another component in a mechanical system, such as a rack or another gear. The speed and torque of the rotation depend on the size and arrangement of the gears involved.
When changing the gear ratio from 3.23 to 3.50, you must replace both the ring gear and the pinion gear. The ring and pinion gears are designed to work together as a matched set, and using them separately can lead to improper meshing, increased wear, and potential failure. Therefore, for optimal performance and reliability, it's essential to change both components when altering the gear ratio.
