8.8 rebuilt but now have issues. Need advice

So this past spring i rebuilt the 8.8 that i swapped into my fiances 95 YJ everything went good and has been fine since. I used royal purple oil to break in the gear set and i used lucas after. We have put maybe 2k on the axle since he rebuild and everything was fine till we went to Haspin the other weekend.

While toying around i noticed a "twisting metal/stressed metal" sound form the rear tire. Thought maybe it was loose lug nuts or caliper bolts. check all that it was fine. ran into town and we could only hear the noise when turning. Nothing going straight.

Got back to camp put it up on the trailer and spun the rear end and nothing, had my buddy hold one tire while i spun the other and hear not so good noises.

Granted we drove it all t he way from lima to haspin (150 miles plus) and didnt have a problem.

Popped the diff cover off tonight and i see......... nothing.. everything looks great i DID NOT replace the spider gears during the rebuild i was told they were fine and could be reused.

Pics:






Should i replace the spider gears and see if it goes away or is the LSD just now starting to really grab?

Might check the splines on your axles. Especially the side you turned and heard the noise. Just a though.

Might check the splines on the axles, especially the side that was making the noise when you turned the wheel. Just a thought.

Any metallic stuff in your fluid? I'm not that familiar LSDs, but don't they have a clutch pack? If so, how do they look?
