transmission noise
So, 91 22re 4x4 pickup. Transmission is about 2 years old. It makes noise in every gear except 4th. That includes neutral with the clutch NOT pressed. When the clutch is pressed in any gear the noise goes away. I understand that 4th gear is a 1:1 ratio. Pilot bearing is new.
Any thoughts?

It's more likely to be a bearing or gear on the countershaft, which is loaded in every gear BUT 4th, where the power goes directly thru the input shaft and the mainshaft.

That makes perfect sense. I was hoping there would be a transmission guy on here that would chime in. So, guess it needs to go back to the shop because it was just rebuilt about 20,000 miles ago.

you know what the symptoms are, noise in every gear but 4th, pilot bearing is brand new. could this bearing be causing it? seems to me this bearing would be spinning all the time being its on the input shaft. however, you can see from the pictures that the inner race is shot. what y'all think?

I realize this has been dead for 6 years, but did you figure out what was going on in the transmission? Min, too, is causing noise in every gear but 4th, as well as neutral with the clutch not depressed.

The countershaft bearings are by far the most common ones to fail. Fourth gear doesn't use the countershaft, which is why the trans is quiet in that gear.
Many sellers, including Marlin Crawler, sell kits with the essential bearings needed. I recommend getting kits that are made up of the Koyo and Naichi bearings. The only bearing that some kits may not include is the rear output used in a 4wd trans.(33350-22010-77 iirc)
It's not hard to rebuild, but I'd recommend a FSM and some select tools. Gear puller set(cheap on amazon) snap ring pliers, calipers to measure, and access to a hydraulic press.
