Having a leak from the transfer case in the part pictured but I can't find it in the FSM. Anyone have any idea what this is? I don't want to take it apart before I know what parts I'll need to fix it.
It's a plug with and oring inside on ABS equipped vehicles, on non abs vehicles it is used for a vss -vehicle speed sensor, typically the Tacoma.
Thanks for your response.. I have ABS. Guess the o ring is just shot. Is it as simple as taking that bolt off in the upper left hand corner and poppng the cap off to get to the o ring or something more complicated?
