Toyota Tundra 10.5" Rear Differential Ring and Pinion Gear setup. See how to set up a ring and pinion gear set. This differential is typically used in the 2007 and newer Toyota Tundra with the 5.7L Engine. This differential uses a removable differential housing, but the setup is similar to other one-piece housing differentials used by other trucks. Be sure to watch our Differential Side Gear Backlash video for complete setup information. We teach current vehicle technologies to our automotive students at Weber State University and online.

This video helps demonstrate part of the following 2017 NATEF MAST Tasks: A3.E.1.8 " Measure and adjust drive pinion depth.", a priority 3 task. A3.E.1.9 " Measure and adjust drive pinion bearing preload.", a priority 3 task. A3.E.1.10 " Measure and adjust side bearing preload and ring and pinion gear total backlash and backlash variation on a differential carrier assembly (threaded cup or shim types).", a priority 3 task. A3.E.1.11 " Check ring and pinion tooth contact patterns; perform necessary action.", a priority 3 task. This video was created and edited by John D. Kelly at WSU.
