How to install Yukon gear Dana 30 pinion kit?
Coat three or four ring-gear teeth in at least two places with a moderate amount of compound and rotate the ring gear four or five times around the pinion gear in both directions. Rotate by grabing and turning the ring gear, not the pinion. Pinion resistance against the rotating ring gear helps establish a good pattern.
Can a Dana 30 work on a YJ Wrangler?
This will work for the YJ Wrangler front Dana 30 since you’re relying on shims for both pinion depth and bearing preload (not a crush sleeve for the preload like the Dana 35 rear axle).
Can a Dana 35 pinion flatten a Dana 30?
Note: All this time, the tooth contact pattern should be governed by Dana/Spicer chart views of proper tooth patterns for the Dana 30. You’ll do the same with the Dana 35 rear axle. Keep in mind that final torque on the pinion nuts will flatten shims and alter the settings.
How many gears does a Dana 30 pinion shim stack?
I had an axle seal leaking and bad lower ball joints so I figured it would be a great time to upgrade to 4:88 gears and 4340 axles since I am rolling 33-12.50’s. I opened up the diff to find a recent but very poorly installed 4:56. The caps were on upside down and it had about .100″ backlash so I am essentially starting from zero.

Where are the shims on a Dana 30 pinion?
By placing the plate on the bearing cap surface in the housing and checking the distance to the top face of the pinion, then subtracting the plate thickness should get me near dead on the correct shims if I have the pinion in with no shims and snugged down to about 80-100 ft/lbs.
Can you change the races on a Dana 30?
You shared that they’ve only been installed a short time, presumably the races are not damaged. Once you get your trial fit (pinion depth, carrier centering for the right backlash, and the preload shimming for the bearings of the Dana 30, you can disassemble and change out the races.
