So I posted awhile back that my transfercase was REALLY loud when driving. My vehicle is a 73 FJ40 TLC, V8 vortec, nv4500, stock TC, yadda yadda. Before getting it on the road I replaced the gear oil in everything and made sure all was topped off. It was fine for awhile then began to get very loud. Well, I figured that the TC was bad since I knew I just topped the gear oil off and was sure it wasn't because a lack of gear oil. The TC was rebuilt about 2 years ago but has less than 2k miles on it. It did sit for awhile without oil in it but I checked it over before install and everything looked ok.
Here's the weird part. Today I decided I was going to drain the TC and check the plug for metal particles as I figured that the TC needed rebuilding because of all the noise it was making. I drained the gear oil and a very minimal amount came out, probably enough to fill 3 to 4 coffee cups!! Weird as I know I filled it up until there was gear oil running from the fill plug. I was also planning on pulling the inspection plate to look over the inside but now am wondering if I should just fill er back up with gear oil and forget about it. Weird thing is that I have no idea where that oil went? There were no visible leaks other than a small leak that shows up (puddles) below the ebrake drum. It was a very minor leak and most of the time was just a drop that sat on the bottom of the brake drum and I did not get any puddles or anything else underneath the car. Is it possible that more of this oil was coming out from the seal on the rear of the parking brake drum while driving? I doubt this as there is no sign of gear oil underneath the car, only a little grease from the driveshaft yolks. OR is it possible that the gear oil has gone the other way back into the NV4500? Can't figure it out, Any thoughts are greatly appreciated as I think my cruiser now has a ghost!
later,
Noah
