Alright, so some have probably seen what came out of my transfer case a couple weeks ago (https://www.dsmtuners.com/threads/what-did-you-do-to-your-dsm-today.382387/post-153883697) and today had some time to actually open it up and take a basic look. Keep in mind, this is my first time getting into a transmission, transfer case, or differential.
The gears themselves look good still, but I can't say the same thing for the tapered roller bearings -- especially the inner one. Reading Tim's breakdown (https://www.dsmtuners.com/threads/first-time-dsm-owner.527605/post-153754810) was beneficial as it seemed to validate that this bearing may have some excessive play. I'm not 100% certain how solid the bearings cage halves should be, as they both (inner and outer) have play, but the inner one seems to be a bit more. Not a big deal, I'll replace both.
Where I'm now thinking there may be a bigger problem is the inner bearing race. It can be rotated in it's spot within the front housing. The shim is there, but you can actually turn the race. That doesn't seem right to me. In fact, it came mostly out just by fingers, then the rest by a literal tap with a pin punch and hammer. At that point, I didn't bother disassembling the mid or tail housings and instead decided to seek counsel. The outer race pressed into the side cover is immobile, at least, by hand movement.
Does this spell doom for the transfer case?
Can provide pictures, if it helps, of the rest. As I said, the gears look good. Wear pattern is well centered on the splines, and there is no heat scorching or deformities visible, but I don't have measurements because if it's trash, there's very little point in getting things checked further.
