So I was planning on starting my SYE install but looking I se I have an oil leak, at what I could find, was the shift detent plug on the bottom of the transfer case. I can't find a part number for this o-ring. Can anyone help or fill me in on what it is if it isn't the shift detent.



thanks

 

What year and model transfer case?


If it's a 231 the o'ring part number is 4338956 (1990-2001). $5.56 at the dealer.
