t-case noise?

[taylorblake831]

Yesterday I went mudding and as I was coming back through on my way out I had a grinding type sound coming from my tcase area (had 4hi locked) got out of the mud unlocked it drove about a block and it went away I gone through 4hi 4low locked and unlocked can't reproduce the sound at all, do you think it could have got to hot and made a bearing grind or something like that? I have no idea I'm gonna change to fluid this weekend and check to see if I get a lot of metal shavings, any ideas truck has 90k on the clock maybe taken in of road 6 times in the last 15k miles

My brand new t-case had a hiccup the first time I used it a month ago or so. I just think it's the nature of the beast. If it's working fine, I wouldn't worry about it.

If no other symptoms, probably just mud up against the driveshaft, in the U-Joint or something.

Drained both of my H3's and slapped in some RP. 122k & 86k the fluid was dark, but zero shavings!

You shouldn't really get shavings out because there is a large flat magnet just in front of the oil pump screen. Any ferrous material in the oil gets pulled to that magnet by the oil flow path. When you split the cases on the transfer case, you'll find the magnet is completely covered in metallic fuzz.
