Hopefully the repair will be done tomorrow, but here is the video of the off-roading trip we went on. If you watch till the end you'll get to see a bit of the oil leak as it happens.

Update:

So I got the oil pan sub assembly replaced at Toyota. Thank goodness I had the employee discount or it could've cost in the $2,500 range. Here are some pictures.

Here is the front differential being lowered.


This shows the old damaged oil pan, you can see the places other than the crack/hole where the diff contacted the oil pan.



This is the rear bracket of the front diff that was missing the 2 bolts. One bolt screws in through the bottom and the other through the top.


Here is the old oil pan removed



And the new oil pan

Damn, those pix make me cringe.

No warning signs that the bolts were missing? I would've thought there would have been some odd clanking going on.
I'm going to check mine in the morning, you have made a bunch of us paranoid, lol!

Well yes actually,there were thud sounds happening, check out the thread link below and I go into detail about things I was hearing and when but no one was able to diagnose the issue until it was too late. Lots thought it was just zerks that needed greasing or something.

Thanks for the heads up on this issue. Just checked my MT's and they look to have different Case design. One bolt easily visible at the rear and nice and tight. I struggle to see how it could have been anything but an omission on a reinstall. The bolts drop in from the top and I can't see a mechanism for backing out. Noticed the rear main seal on one starting to weep. Get to watch that now.

Thanks for the tip and sorry to hear about your troubles. I just checked mine and they are fine. I've never touched them so it seems like somebody didn't properly torque yours when reinstalling.
