All that is left to do is to reattach the rear drive line, reconnect the crossmember, and add some gear oil! Tip: Before adding gear oil, it wouldn't hurt to ensure you can shift your transfer case between high and low ranges like normal. We recommend a GL5 75W-90 gear oil, and expect to use 1.5 quarts.
If you did not install the center differential spool, then the job is done!
If you did install the center differential spool, then there is one simple step left: Install the center diff lock switch (this switch is supplied with the spool). First, unscrew and remove the radio and climate control bezel to expose it's wiring harness. There will be an unused male plug with a female shorting-plug (or jumper-plug) attached to it (circled in the below image). This shorting-plug simply shorts a circuit that we'd rather like to operate manually. Unplug the shorting-plug, discard it, and then plug in the new Center Diff Lock switch in it's place. Install the new switch in place of the dummy switch cover, and then replace the bezel and you're done! Tip: It may be difficult to get the new switch to extend far enough to attach to the bezel. You've got two options: Reroute the plug's harness to gain more length, or tug gently on the plug's harness to gain another inch or so. With a little effort it will fit without any problems -- Toyota originally designed your truck with this feature, we just never got it in the States.
In closing, double check all bolts, inspect all areas serviced for any loose wires or hoses, and go out for a test drive. Ensure your shift lights are working properly and that your speedometer is functioning. If you installed the center differential spool, then be sure to
NEVER engage or disengage your new center diff lock switch while the vehicle is moving.If you have any questions at all, do not hesitate to give us a call toll free at (888) 94-CRAWL [888-942-7295]. Go out and start CRAWLING!
