You should be able to get some rotation out of the pinion by hand, but anything near 90* is sounding like a backlash problem. In and out would be more bearing, unless one is completely destroyed somehow. Definitely pull the cover.
Front Driveshaft Issue - To much Slop and Gears Making Clanking Sound
I got a 2010 with 513's and ARB Lockers in front and rear. I recently been hearing what sounds like a low speed clanking noise. The noise isn't audible of speeds over 40MPH. It's really noticeable at under 20MPH and I can hear it going slow. At higher speeds, there are no aduible hums from the drivetrain or vibrations. Other than the tire noises, everything seems to be just fine. Four Wheel low works and clanks, four wheel high clanks, and in two wheel drive it clanks at the speeds mentioned above.
It's coming from the front differential. When I stopped it yesterday and put it into park, I could turn the drive shaft a full 45-90 degrees and hear something clank in the front differential. I'll be pulling the differential cover today just to have a peak inside.
I've searched for a few hours while it warms up here, I've seen some mention about pinion bearings being loose or about to fail... Backlash not being set right and it being an issue...
These gears have about 10K on them and never made a single noise.
Can anyone shed some light on what issues may be ahead?

2010 Jeep JK Drive Shaft Excessive Play - Potential Backlash Issue - YouTube
the sound you can hear above is the clanking noise i hear when driving at 1-20 mphs...

Wow! Yeah, I'd say you have something going in there.
Sounds to me a broken ring and pinion
Has to be a pad bearing/too little preload, no? A broken ring/pinion gear would make all kinds of noises at all speeds
Could be in the locker too. If you turn it slightly back and forth can you feel the backlash?
Pull the diff cover, betting stripped pinion..
A stripped gear could cause that much rotational play in the driveshaft?Pull the diff cover, betting stripped pinion..
Sure it could, it may not be completely "stripped" but if 2-4 teeth are chipped off the pinion, the pinion will rotate that far until a "good" tooth bites the ring gear..A stripped gear could cause that much rotational play in the driveshaft?
Or there is a horrendous amount of backlash.
i'm such a ******* idiot. i'll upload it in a sec... whether its the problem or not, it needs to be addressed.

Tack weld them caps bro!
certainly a good thing that you found that issue with the driveshaft though before shit gets bad.

guys the teeth looked perfect. i couldn't rotate it all the way because the tires are on the ground, but from the teeth i saw with the diff open, all looked well on the inside.
You were way offSwimmy, swammy, Swanson, SAMSONITE!
Well that'll do it and give you some pretty similar symptoms to what I was going with. I figured sir retard would have noticed that!
Regardless, you should not be ale to rotate your driveshaft even half that muchguys the teeth looked perfect. i couldn't rotate it all the way because the tires are on the ground, but from the teeth i saw with the diff open, all looked well on the inside.
