I wasn't able to shift my truck into 4WD, so i climbed under the truck to see the linkage not hooked up to the shifter. I went to the stealership to buy a new bushing for the t-case side and get what ever connects it to the bottom of the 4wd shifter. They told me that the shifter is all one piece. I don't have problem buying the whole shifter if needed, but I don't see why I would have to. It looked like to me all that connects the bottom of the shifter is a bushing and a clip, but maybe not. Has anyone else had this issue? I have searched but really didn't find anything on the forum.
