First pic looks pretty close, but the second... not so much. I'm guessing the pinion could use a little less shim.

To much 'inboard' contact in both pictures. Also need to go deeper into the ring gear.
Take your readings in more than one place.
Bring the 'p' out .002-.003" and bring the ring inward about .005".
Do you have the carrier bearings pre-loaded?

Thank you for the timely responses, guys!


Lumpy, I know you have LOTS of experience in this area, so I want to make sure and understand you 100%:

Does this mean too much "toe bias?"

This is because you think my markings need to go closer to the root, correct?

Sorta...I lightly tapped the diff in with a mallet but it wasn't super tight or anything.

Yes & yes.
Torque the bearing caps to 80% and then read a pattern. Same with the pinion.
Hope you used a solid sleeve on the pinion. I hate and refuse to use crush sleeves.
What axle is this?

This is a narrow track Dana 30 for a CJ. 4:10 spicer gears with a Spartan.

I ordered the Yukon master rebuilt kit; it didn't come with a crush sleeve which kinda confused me...I figured if I needed one they would come with one. Now I am second guessing everything...

http://www.quadratec.com/jeep-replac...a-30-front.php

is the crush sleeve or solid sleeve the thing between 10 and 11 in this diagram?

I should also note that there wasn't a crush sleeve in the axle when I took it apart...but that doesn't really mean jack considering the P.O.

Not a real good draw'n for reference.
But, I think that is it.
Very surprised there isn't a PN# for ID?
What was the +/- marking on your pinion?

+.05

Old pinion says +3...which I interpret to mean .03 not 3"

Its probably +50 as in 50 thousands.


I had issues with my shim stacks, and like I said I wasn't using a crush sleeve, just the thrust washer like on the D60


I torqued my pinion nut to 200ft and got my preload shims to measure out 16 inch lbs

WOW-+.05 is a bunch.
Take your time-You have done well so far.
Also, squirt some oil the the bearings to lube them.

There is no crush sleeve on a CJ Dana 30 (or CJ Dana 44 for that matter).
