Another quadratrac question

[tthstrm179]

1978 CJ7 , AMC 304 , QuadraTrac /GM Turbo 400 . The QuadraTrac has the milemarker 2wd conversion. I've posted the saga of a chain change on this, and here is the summary:
Changed the chain, sealed it up, noticed movement (in out in output shaft).
Figured out that although I torqued the rear yoke, it was not all of the way tight in its bearing, and was sliding in and out. Tightened that.

Found metal in the ATF of the QuadraTrac . Drained, split case found signs of wear on the power side of the sun gear, attributed to not inserting sun gears evenly on install.

Reassembled, everything turns smoothly, and then noticed this:

With low range in Neutral (center position) Transfer Case turns with almost no resistance, chain seems to run smoothly, no binding, no noises, seems to move perfectly.

Engaged in high range, there is a bit of resistance and a slight squeal when turning in the forward direction. Squealing seems to come from low range unit. Not loud, not metal on metal sound, just a slight squeak. Not hard to turn but can feel resistance. When turning in reverse, quite a bit of resistance.

I happened to pick up a spare QuadraTrac . Should I change out the low range or is this normal?

The gear reduction unit on a quadratrecs is a fairly simple device. It should not be making the noise you talk about. I would take it off and flush it out with some cheeo Transmission fluid. See if that helps. Also make sure you fill it with the proper amount of fluid once it is replaced. The gear reduction unit is filled separately from the main body of the Transfer Case . Rod

I took the low range box off and noticed that the case turned smoothly without it connected. This was because without the low range box, the gears are turning independent of the Transmission .
I flushed the spare low range box out with ATF, confirmed that everything spun smoothly, and installed it.

The squeak is still there. I can now determine that it is coming from the output shaft area of the GM Turbo 400 - which is something I have not messed with or removed.

I think all is well. Does anyone know if an automatic Transmission provides a small amount of resistance even when in Neutral? Is there more resistance when in reverse?

Thanks

Yes, even in neutral the out put is stiff to turn. There is a bearing between the Transmission and the tranfer case, located in adapter housing. Might check that. Rod
