What have you done to your square lately??

Weighed it today. 4245# with me and both tanks full. ~3865# dry weight

The later ones called for ATF. I'm not sure if running ATF in an older one would cause problems though.

The seals did not like it - I tried it when I 1st got the truck as I did not have a owner's manual, but have a 82 FSM which called for ATF.

Unknowingly I bought synthetic ATF which may have been what it did not like.

That said, any ideas if the overfull condition would cause it to make funny sounds only at a certain rpm and above?

I will find out Saturday morning, but if anyone knows the answer before then, cool.

I don't think an overfill condition in a gear driven t-case would cause noise, probably only leaks. It's "splash" lubricated like the differential, no pump to cavitate or surge.

I may be wrong, but I don't think the np205 takes atf, but gear oil. In which case, the mixing of the two may be problematic.

Your correct. The 205 just takes gear oil. That said I have heard some run ATF. But also it's just gears and bearings and I don't think his normal running so far would have hurt it. No oil would be worse that half and half over full

I'll be pulling them off of the Suburban at some point. One has a little rust on it though.

Are y'all talking about the bumperettes? Those things on the front bumper that protect it from an forward impact?

Yeah. They have gained the nickname around here as "bumper thingies".

Ohhhh got it. That’s rough.. just a gear swap or just a posi swap?
I know people say that it’s ok to swap the ring onto the new carrier but sometimes it’s better to take that little extra time ( and money ) to knock it all out. Usually if I plan on keeping something old, I spend a lot of time inspecting. And if I feel slightly nervous I swap it out.
Cheaper to spend money on a new crush sleeve to inspect the pinion bearings VS a whole rebuild. But I’m a wiggly one. I’m no rear end expert but I have rebuilt a lot of gear boxes in industrial settings.

Old rear was a 3.08 new one was a 3.42. I left the 3.42 pinion alone and just put the ring on the new posi and put it all in

Get a 12 bolt out of a 4x4 with 6 lugs and make a Lincoln locker. You'll love it

It all depends on someone's tolerance. Personally, I love having locked axles. Some people hate it. Just like some people like manual hubs and some like drive slugs or auto hubs.

Sadly, you were correct- the overfull was not the source of the noise.

Would have been too easy...
