Building The Ultimate Dana 18 Transfer Case!

Building the ultimate Dana 18 transfer case! After months of planning the Dana 18 for the Willys CJ3B 4 speed swap is ready to go together. Tons of trick parts from places like Advanced Adapters and Teraflex! Plenty of upgraded parts that way out perform stock! And my little tips and tricks to hopefully make your Dana 18 leak proof, bullet proof, and custom! This is an exciting step in the 4 speed swap series because it means it’s time to start bolting things into the Jeep!

I took the interlock pill out of my Dana 18’s in my 55 M38A1 and my 65 CJ 5. They did that to prevent people from torquing the yoke off the rear axle or the back of the transfer case.

Excellent video, as always, Jacob. One note on the shifter lock out pin you left out...that's fine with the twin stick because it allows you to have 2WD and 4WD low range. BUT, with the single stick, it MUST be in there or it just won't work. Just thought I'd mention that in case a viewer was doing a single stick. As for the large hole case, you were correct that it was 66-71, but to the best of my knowledge, the large input hole was V6 only. They are nice too because it allows the transfer to be removed without having to take off the gear from the trans....the gear will slide through the larger hole.

This is a great instructional for anyone doing up a transfer case and the relaxed way you went about it makes it a whole lot less scary. Thanks for sharing.

I don't know if I'll ever use this very informative info but I sure am glad to have it.

[@charlesnoel9081]

Your video is great. Very detailed. I need to do the same to my '58 cj-5. I build machinery by trade. On the use of the crimp nut rather than the castle nut. It's best if you have two or three threads sticking out of the nut to get the correct locking you are looking for. You can remove the needed metal from the bottom of the nut to get the correct depth and torque. Without the exposed threads, the locking crimp may not hold. Also, you got your second shift lever spring on the wrong side. the spring holds the lever end into the shift rail. With the spring to the inside of the shift lever, it will keep the lever leaning away from the groove in the shift rail. Thanks for the great video that will help people for years to come.

Great build,a lot of work getting every thing ready to put together and some machine work to make those Tera Low Gears work,lucky finding them,with the T-18 and modified D-18 you should be a happy camper,Metalshaper,Brian,cannot be beat,he has forgot more than a lot know about Jeeps,watched all of his videos,they have helped me many times,I know why you left the gear off between Trans,Transfer Case,you may want it to be a surprise in next video,so wont say anything to spoil it!Thanks Jacob,keep the videos coming!

[@roberthanna5977]

Very helpful, and I appreciate how you walk everyone through the things and don't hide your mess ups. Especially grateful for the tips and product reference links. Thanks for doing this!

[@triplealley]

Excellent job/video. I have a T-18 and researching how to make it not LEAK. Lots of people permatex the splines, threadseal every bolt, upgrade the pan, and sometimes use two felt (or combo with rubber) seals. Would be great to see you really emphasize these parts of the build. Thanks for this.

[@scubasteve7946]

Awesome work. Looks great. IMHO, with the 4 speed you could have skipped the terra lows and been happy. That compound low 1st gear really drops it down slow!! Especially since it's in front of the T-case, it's basically doubling the crawl ratio over the 3 speed anyways. Just thought I'd mention it in case anyone was contemplating the similar thing.

[@SF-fm9hs]

if you are having a problem tighten or loosening the fork set screws. A 3/8 extension will work. use the dive part of the extension will fit perfect over the set screw, and use a adjustable on the square drive to turn it .

[@gillafunk]

Thank you for taking the time to make this video. I am currently assembling my Dana 18 myself, my first time doing transmission work. Your video was very complete, very descriptive, detailed and well documented. I’m gonna wrap everything up tomorrow and this video is going to make all that a lot easier for me. Perfect timing. Thank you very much again

[@MikeyGG34]

Putting a Warn overdrive, or Saturn overdrive on the back of that Dana 18, are you? Your right about Brian, metalshaperJeep. I've watched a lot of his stuff, I subscribe. Very nice and knowledgeable man.

[@johndoe43]

Good job. Brian is top notch as you know.

[@steamboat1341]

Thank you again for sharing your knowledge, a great informative video. I’m searching for my project and these videos help tremendously.

[@MikeyGG34]

And Thank you for your videos also, very informative, and easy to follow. You do make it sound and look easy, but I know better. Thanks again, you got a new subscriber.

[@toddkennedy7623]

I enjoy watching your videos and I watch Brian's videos also

[@pepejoseaquiles3146]
