Metal parts in the transfer case oil

[Mikkel]

Hi, new to the site, and looking for help on my 80 series land cruiser.

When changing the transfer case oil on my 92 80 series today theese parts came out with the oil. I have had the car for 4 months and there is only a smal squeeking sound when im driving without throttle.

Any ideas on where the parts Are from, and should i park the car and do a transfer case reabuild?

Thanks for any help here

Snap rings…. Or bearing material. Probably the latter.

Drive it till it blows up. Or address it now.

I think it is an oil ring - there are a couple in the rear extension housing on the output shaft.

If it were me, I'd be pulling the t-case apart...those aren't just your average "shavings". You can pull most of it off without unbolting from the transmission if you want to split under the truck...that or just pull the whole thing as a unit to check everything.

Check out this great video series on rebuilding the t-case...huge help when I did my gears myself.

Thanks! Yes that looks like the one

There are two on the output shaft. They have a unique looking locking mechanism.

Nice! Thank you! I can see them on the very last part of the video. Looking forward to a nice weekend pulling it apart, if i can get the correct rings

Thanks. How long will it last without a ring. Do you think it has already made some damage?

The question is maby if i can drive 1 hour to the lift, or if i should put it on a trailer?

I don't know. Sorry.

I'd be most concerned about the metal bits floating around the transfer case causing collateral damage or getting caught in passageways.

I'd trailer it. FWIW, those sealing rings are used in the transmission, too, except those are plastic. The function is to ensure the oil gets from one end of the shaft (the input end) to the other (the output end). They're used to make the shafts cheaper to manufacture.

If the oil flow is not as designed, you risk starving the bearings/gears. Then your problem becomes very expensive because you risk breaking a gear tooth and that'll ruin the shaft and then you'll need a new gearbox. Right now, since you're not hearing any grinding, you're likely just in need of a new seal, and maybe a good cleaning.

Thank you for info and advice
