Currently at:

.0195" shim behind driver side carrier bearing
.098" shim behind passenger side carrier bearing
.060" shim behind the big pinion bearing cup
.076" shim between the pinion and small bearing

Backlash is at .009"

Pinion free spin torque is about 3 inch pounds w/o seal. I'll be removing a few .001's from the preload shim pack to bring that up. These are new Strange gears and Timken bearings.

It looks to me like it might need some more pinion shim to bring the pinion closer to the axles. What says the hive mind? How much of what?

Coast side



All that shim on one side is telling you dont have enough shim under the inner pinion bearing..
You need to move the pinion out toward the ring gear..
Add about .020 or so under the inner pinion bearing and watch how it falls together..
Once you move the pinion out some the back lash will setup much better..


Also its hard to see a good pattern cause there isnt much load on the gears. Have a friend hold a wrench on a ring gear bolt and you turn the pinion with the breaker bar. Tell him to try and stop you from moving the gears...
The pattern will look much better.
