Front driveline slack

D-30 with a Spartan locker.
Lots of noise and slop in drive shaft. (i know zip lockers click but this has got worse)
Replaced u-joints thinking they were stiff causing binding....they weren't that bad.
Now with vehicle sitting I can twist front drive shaft 1/4 turn each direction.

Is it slop in the transfer case chain?

Or messed up ring/pinion from install?

Pretty cut and dry on the install isn't it? shouldn't be a need for shims or anything more??

From what I am told; it is normal. I have the same in my d30 with my aussie. I tried to source it down for MONTHS, only to find the installation papers mentioning increased backlash is normal for an auto locker.

Yep, between the required backlash (slop) between the ring & pinion gears & the additional backlash/slop an automatic locker adds, you'll get a lot of rotational slop at the pinion shaft. Alarming at first until you learn that it's normal & required.

And if you have a manual transmission, you will hear it a LOT.

Thanks for the feedback guys. Glad its just normal.....not happy about the clicking. It's only the cabin jeep so it's not that bad.

I have an Aussie in my front (High pinion) dana 30. I only hear the ratcheting / clicking when in 4WD. I would check your fluid in your front axle. Perhaps move to a slightly higher weight? I use 80w-90.

Got the heavy weight oil in and level is good. Going to do some recon next week on just to be sure things are lined up right in there.
