Yes, I searched, and watched videos, which has only left me MORE confused.

You will tell me; "adjust the 17mm drum brake adjustment bolt on the drum brake which sits just behind the transfer case."

I DON'T HAVE THAT BOLT!!!! Nor any place where it looks like it would go. I looked on both sides. I've seen the manual, I've watched a dozen videos...I don't have that friggin adjustment bolt! Also, when I look down under the lever boot, there is only a rubber nipple, nothing to adjust there either.
Soooooo what the heck is up with my disco???

 

 

Did the bolt fall out?? Check to see if there is a hole

 

Pretty good looking leak from the transfer case.

 

So it's in the inset groove sort of in the middle. Feel around with your fingers.

 

I felt around, there is no bolt and no hole.

 

 

Alright, I'll get much deeper under there and look again. Maybe it's just covered in oil.
