2015 Tahoe/Grinding/rough noise from front of vehicle

[fatmonk8]

Gear oil replaced, bearing replaced, seal replaced.

Everything is bolted back up.

Still a crunch noise. Regardless if in 4wd or 2wd

Did you open up the differential or just swap the bearing? With that much play, and the amount of debris you had on the plug, I would want to see what's going on inside.

It has to be removed to be opened?

I believe so, but there may be a way to split it in place that I’m not aware of.

Damn, I unfortunately can't drop that diff anytime soon.

Man I finally got brave enough to jack all 4 off the ground and out it in driver in both 2wd and 4wd. Felt super sketchy lol.

But I didn't hear a dang thing.

I also dont see any big or small pieces of metal in the old fluid either

Your magnet grabbed some decent sized pieces and you may still have some left in the gear case. The metal on the rag in the photo came off of something in your differential.

Yeah I agree. I am just not understanding what is going on.
