The drivetrain Gods frown upon me. (Transfer case related)

[Coup D E'Tat]

Where to begin.

I'll start by saying that a little while back, my transfer case that I had replaced as soon as I bought the car locked up on me with maybe 1,000 miles on it.

I get the car back, and a few days later notice something vibrating horribly 40 MPH and above. Look underneath the car, the case is leaking again. There is fluid stained/burned on my exhaust. Back to the dealership. I go back a few days later, and they tell me that the fluid on the transfer case and the exhaust was probably just some remainder from when they filled it up, and that the leak I was seeing on the ground was from the oil drain on the turbo, which I knew was leaking a tad, and that the vibration was from 2 bolts MISSING from where the driveshaft bolts into the rear end. Super.

I limp the car home (unrelated problem, turned out my BISS fell out,) replace the 4 driveshaft bolts with new hardware, took it around the block once. No vibration up to 55 or so. I'm a happy camper.

The car sat for a while because I was getting some other stuff done on it to prepare for DSMLink. I had put a total of 13 miles on it from getting it home from the dealership, then driving it around the block.

I looked underneath a few days back and noticed a puddle coming from, where else, the transfer case. Although I had a hunch before that the leak was from the case, I just figured maybe I could be wrong. But alas, I was right as usual

I went back up there today, and it's been maybe a month, I'm not sure exactly, and tell them what is going on. He says "No, no. The fluid was from the line on the oil pan." I told him quite specifically that I pulled the drain tube off of the car, and that the case is leaking without a doubt. I told him that there were 13 miles on the car, and asked if they replaced the seal on the driveshaft. He says he isn't sure what all is replaced, but I can bring the car back up and they'll look at it.

So, I'm going to take the car there as soon as DSMLink arrives, and tell them to put it on the rack and I'll show them where it's leaking from.

Could it be anything else aside from the seal on the driveshaft not mating properly to keep the fluid in?

Thanks, and sorry for the novel-style post,

Jesse

In case anybody was confused this was the piece I was referring to. The end joint that slips into the end of the case.

In the end of that yoke is a 'freeze plug'. That is what leaks. Clean the inside with brake cleaner and dry it out. Put a good bead of silicone around on the inside and let it cure. Put a new seal in the xfer case and you should never leak again.

Your power steering rack can leak and drip on the exhaust making it look like it's the yoke instead. Be sure to loook closely when you're under there.

I am 100% sure it is the transfer case, but thanks for the advice. The car is going to the dealership one last time in the upcoming days (as soon as I get the car running,) and if I don't see any progress, I'll try your method on my own.

Thanks,
