Looks good to me. I would run it.

Thanks guys, I'll button it up and put it back together!

Backlash came in at .008, high end of spec.

I'd be happy with that backlash.

 

[Gravy]

I think that's fine especially since you'll have it at freeway speeds.

 

[Greg]

Rear axle pattern check, please! Backlash came in at .004

I feel like your just posting these now to show off... 😃

Pattern is great! but on a daily driver I would open up the backlash to atleast .006

Every spec I have seen on aftermarket gears for a JL or JT has been .006 - .010

Interesting! Perhaps I'll see what Yukon recommends, these specs are for all gear ratios from Dana.

The front axle spec was .006-.010, but rear is tighter.

Can someone let me know your thoughts on mine?

 

[skippy]

Definately runnable but I would add some pinion depth and try to bring that coast side up a bit. If your backlash is on the looser side you can tighten that up and that might help with the pattern.

 

[Shawn]

Thanks for the reply. My backlash is set at .008 with an acceptable range of .008-.012 so I figured I was good. I too thought the pinion was too shallow and planned to add a thicker shim and the final.
AppreciAte the feed back, been messing with this for a couple of days and started second questioning myself.

I don't know why y'all are so picky about patterns. This one has been running fine like this for 5k miles now. I mean, it does howl, but I just turn up the radio! 😬😬

Ohhhhh...nooooo..nooooo
