Figure 29. Replacement shift forks were found on ebay for a reasonable price, and they have now been installed in the transfer case. The wear caps have been put on both of them before installation.

Figure 30. Installation of the new shift rails starts with detent springs, also called poppet springs. This transfer case is known to pop out of gear. To stop this, two Number 6 washers were put in the bottom of each spring hole to stiffen up the spring. Put the ball in then push it down with a punch or screwdriver and install the shift rail. Be careful, if you slip, the spring and ball will shoot out of there like a bullet. Ask how we know this. One note of importance here, the factor aluminum plug that covers the hole above the shift rail was damaged. Here you can see what was used to replace it. These are size 6 Parker SAE hydraulic plugs. They are the same thread size, and work beautifully and look nice. If you are not using the 4x4 indicator switch, you can use two of them as shown here.
