Now that we have brakes, decided to start it up and check the transmission and transfer case...a new project has emerged...
Should have taken a video but the noise is coming from the transfer case, sounds like chewed up gears where it kind of slips then catches, slips then catches...terrible racket.
When I pulled the drain plug a few days ago, no gear oil came out. Thought maybe it had leaked out over the years. Pulled the drain plug after this, quite a bit of junk in the oil.
So next plan of action...pull transfer case apart and see what we have. Kind of wanted to put in a twin stick anyways and get rid of the vacuum actuated mess.
