Where is the leak?? I only see something wet at the two bolt heads from the aft transmission mount. Could be the aft transmission seal, eventhough i don't see any red colour from the ATF +4.

Re: '00 WJ Transfer case vent location

I can't really tell where the leak is either. looks like it comes from the trans seal to me as well. I did not notice any red fluid anywhere. It was black soot. I haven't been back under her in a few days, there's been quite a bit of rain. I'm going to drain and fill the t-case, and clean everything with Simplegreen, hopefully after that I can find the leak.

Re: '00 WJ Transfer case vent location

I would not worry too much about the black area. There is probably a bit of swetting from the T-case halfs seal. Dirt sticks on it and leaves this black area.
Just keep an eye on the fluid level to see if it doesn't go down.
If you change the fluid, use the "special"mopar fluid or just Mobil 424 (same fluid), whichever you can buy easier.

Re: '00 WJ Transfer case vent location

I'm worried about the humming noise i am getting around 40 mph and up. it increases with speed and does not seam to matter if I am turning. I don't think it's a wheel bearing... To be honest, I have to wait till this weekend to buy gear oil and i need NV247 from the dealer for the t-case... Hopefully, the clogged air vent in the t-case just caused fluid to leak and i'm dealing with a lube problem... hopefully... I had the same noises with my old jeep, never figured it out, and ended up selling it for $600. This truck is worth way more to me, i'm gonna be a mommy soon, so I need to get it figured out. I refuse to pay someone unless I know exactly what's wrong, then I just pay for there muscles...lol

Re: '00 WJ Transfer case vent location

Did you (or some muscles) check the T-case fluid level? Humming noises can have several reasons and the first thing to check is the T-case and diff fluid levels.
And for the NV 247 T-case its indeed the stealer fluid or Mobil 424 (the stealer fluid = Mobil 424 minus the price)

Re: '00 WJ Transfer case vent location

$15 a quart for the NV247, not sure about the mobil 424 price... No, i didnt check yet since i have to wait to get the fluid till the weekend... just trying not to drive it. once I open it I'm going to drain and refill... im happy to hear you think it could be low fluid too. the t-case breather vent had been totally clogged, i fixed that part the other day. At first I thought the whine was gone, but it was back that afternoon... I'll let you know what happens this weekend. Thanks

Re: '00 WJ Transfer case vent location

You will need 2 qts for the T-case (the NV 247 takes 1.6 lts).
For the front differential (Dana 30) you will need 1.18 lts of fluid and need to know if it has Quadra Drive or not. (Quadra Drive axles need limited slip additive in the fluid). Also some RTV will be needed to seal off the differential cover.
