My transfer case will not shift into 2H or 4H but it will go into 2L. I have a 1971 fj40 with an early 1975 drive train. Im hoping its just transfer fork however Ive noticed I am getting a lot of play in my gear shift. my questions are; Can the transfer fork be replaced while the tranfer case is still in the truck? By looking at the picture does the linkage look correct as far as the amount of play ? also Ive noticed the shift boot can come out of the shift shaft, is that correct? I also noticed that Im missing the shifter mounting bracket. Thank you for your help.
