Go ahead and rotate it just a bit, without the fluid you don't want to be spinning it all over but it can't hurt to give it a little push. You have been running your wheels at thousands of RPMs with that thing lodged in there so it wouldn't hurt to give it 1 or 2 more turns. It's hard to see exactly what is going on in there with only the 2 dimensions we get from a picture (no depth perception). See what it does when the gears are moving.

It's probably part of the metal friction disc(s) they have a tang, or "dog" that engages the carrier. Each metal disc has 2, I have seen them sheared and mangled before. They dont seem to leave many shavings though, so you could prolly get away with a clutch rebuild (parts around $80).

I rotated it, it seems as if its been that way for while now. it doesnt make any noise just moving back and forth. however, it started just pouring and I bolted the cover back on and came in....
Is there supposed to be anything in that slot in the picture? (bottom left in front of ring gear) While I was turning it, on the other side, there was a flat piece that was sticking straight up on the outside of the spider gear that looked like it went there, but I cant bend it.....
Any ideas on why this makes it make noise going around corners at highway speeds? There also was not a lot of jewelry in the fluid, just speckles and one piece that was about 1mm big. Is this going to be ok to run with if I plan on replacing the carrier anyway?

The right way would be to rebuild the LS. I understand the need to get home and that's where you have to decide if you're going to roll the dice or not. Here's an article for review on what is involved. This deals with installation of gears in a Mustang 8.8 but it also covers rebuilding the LS and gives part numbers and torque specs.

That looks like the thrust washers that are under the spider gears may have failed. I had an 8.8 in a Gran Marquis that had bad machining where the washer was supposed to be running. It cut the washers up and then began to fuse the spiders to the shaft. I suspect the same thing for you escept it looks like the spider is fusing to the spool housing.
Hopefully you can get the spider gear shaft out easily and then push the axle in to take out the c clip to pull the axle shaft out. You will probably have to replace all the carrier assembly to cure your problem.

how hard is it to replace the carrier? I know, take out spider shaft, take off c-clip, take out axles, remove bolts, remove carrier....But what about shimming it right and getting the right backlash....do I still have to worry about that even though I won't be messing with the pinion gear?
