Stop in for a cup of coffee

It's for the lock ranges of the transfer cases. Can also be for the hubs depending on the year.
yea - that's what I thought - truck was full time 4x4 so no hubs. I wish I had pics of it - 78 TrailDuster that I put 87 SnoCommander (3/4 ton) axles and springs under - 360 with headers and "cherry bomb" type mufflers with STRAIGHT pipe right out the bad... SO obnoxious!! :lol:
