The truck is up on ramps to make it easier to crawl under. Because of the angle, the gear lube level is tilted toward the rear where the access hole is. I'll need to get it off the ramps and on the level to check the gear oil level accurately. If it is over full, I'll drain some out.
When I took the speedo fitting out of the transfer case, I could just pick up the gear (about 4" long, all steel with a square female connection where it joins the speedo cable). There were various grooves and rings on it, but no evidence of any seals or anything else. I slipped it back into place, screwed in the fitting and re-attached the speedo cable. Haven't checked it again to see if the speedo is working correctly. I'll look again for the vent, no luck yet.
