99 Big Bear SE Transfer case oil leak

Hello,

I purchased a 99 Big bear SE locally at a discounted price.

I have been working away at the small issues it has to get it whipped back into shape.

This is the 348cc with high/low/reverse shifter.

I was ready to try and fire it up, checked the oil and it was not even registering on the dipstick. I put 2 quarts of oil in it to get it to register on the dipstick.

I assumed there was a leak somewhere and did find a slow drip that accumulated on the transfer case on the rear of the motor.

Is this the ol’ yoke nut/ rear oil seal issue that is widely documented? Or could there be another cause? I question the rear oil seal since the oil does not seem to be coming out of the boot that covers the drive shaft coming out of the transfer case. There also may be some damage and a bolt missing on the transfer case.

I have attached a few pictures. You can see the oil pooling a little under one of the bolt heads, I cleaned the area with a rag shortly before taking the pictures. I circled the bolt with the oil pooling on it, the possible missing bolt and and area that looks rough, but could possibly be from the casting process.

Any input is appreciated.

Thanks,
T
