Elmo the LJ Build: Gears, Axles, and Traction

Elmo the LJ Build: Gears, Axles, and Traction


Ok so now the Jeep’s lifted. Bigger wheels and tires. Shod with some BFGs. And that’s where most people stop. Yep. And then they don’t have any fun do they? That’s a big mistake, because why? Because their gearing is all wrong, and their
fuel economy goes to crap, and they got no power, and they’re living a nightmare. And they don’t have fun on their Jeep? They have no fun whatsoever. And then at that point then you sort of second
guess this whole Jeep thing, right? Then that’s when you go one tons and 40s. Well, the one thing Neal’s got going for
him, is that he’s at Yukon Gear & Axle. They have some gears here. They got gears, they got lockers, they got
the shafts, they got all the small parts to actually do what you should do each time you
go to a bigger tire, which is to regear so that you can maximize the performance out
of a motor. Ok, so we’re leaving the Dana 30 in the
front? Yep. Because it doesn’t really need to be upgraded. Yeaaah, this is hard for me to say, and you
guys know that at CRAWL, the Dana 30 is like half of a Dana 60. I don’t use them. I don’t use them at all. I give them away. Yeah, they’re cute, but in this application it’s
going to work. It’s going to be perfectly fine for what
he’s going to do. And for turning a 35 with chromoly shafts,
and a really strong locker, it’ll be fine for a long time. So we’ve got 35s, we’ve got new gears. What ratio are we going with on this? You know, I’m not sure, we could probably
look at the box. I’m going to guess that it’s a 4.88. Am I right? Look the guy nodding off camera says yes. That’s where I would have went, cause I
mean, the thing is 4.88s were good for 37s and 35s on the Jeeps. 5.13s work real good on the 40s, but that
might be a little too deep for a 35. Yeah. See I would have gone to the 5.13s, because
these would just be like temporary tires to me on the way to 40s. Those would be rollers for you. That’s right, those would be what I borrowed
until I got my 40s, but those are good. So 4.88s, Yukon good quality chromoly shafts,
A change in the bolt pattern. Yeah, which I thought was interesting. It makes it cooler. Well, it’s a little bit stronger. Yep, and now they’re getting rid of the
unit bearings. Spin Free Kit. Yes, which is kind of cool, cause I mean I
knew they had em for the big trucks, but I didn’t know they did them for the little
Jeeps. For those of you that don’t know, that eliminates
the unit bearing, replaces it with a typical roller bearing, so now you’ve got a serviceable
unit. Completely rebuildable. And something that this Jeep never had from
the factory. Lockout hubs. And these are the cool lockout hubs, the Yukon
Hardcore Lockout Hubs. Yep. They’re the best. My favorites. A lot of grease to put them together though. That’s why those guys have rubber gloves
on over there. You ever notice that? There’s so much grease that goes in that
one little hub. But it works well. I try not to look at mine too often. You have someone else deal with that? Yeah. You gotta put a lot of grease in there, but
once it’s in there that will make a huge difference on this Jeep. So we’ve got the performance back by swapping
in the gears, so now it’s going to perform. But, by putting the lockout hubs on the front,
now on the front we’re not turning that whole axle. There’s a whole rotating assembly there
that now can just sit and live longer. Now we can lie to ourselves and say all these
modifications were done for better fuel mileage. We’re doing all of this. All of this is being done to this Jeep for
better fuel mileage. The one thing that he’s going to love – when
you get in a regular 4 liter Jeep on 29” tires, and you step on the gas that thing
scoots, I mean it’s a lot of fun to drive. It’s like a rocket ship. Now, it’s going to drive like that on 35s. That’ll be cool. And that’s the part that people stop at
the lift and tires, and they’re always disappointed. You don’t stop until you do the gearing. Well they usually buy light bars first. Yeah, light bars and angry grills. But, you know, see I always say, what’s
the one thing you gotta get before your light bar? Lockers before light bars. Hashtag lockers before light bars. You gotta do that. #lockersbeforelightbars. So, and this is getting lockers. Yes, absolutely. You’ve got two choices of Yukon lockers
when you’re going offroad. You’ve got your Grizzly Locker (the angry
bear), and you’ve got your Zip. The Zip Locker. Air actuated locker. Perfect for the Pacific Northwest. Because you can unlock it and it’s open. It’s just like the day they bought the Jeep
brand new off the lot. It’s going to drive smooth and easy. And then hit them switches. And you can go anywhere you want. It’s like a spool. Spools are pretty cool too though. I like spools. So, now we know that it’s up in the air,
35 inch tires, we’ve got lockers (like it should have), we’ve got good shafts, gears,
and, uh free spin – a Spin Free. A Spin Free Kit up front. Spin Free. He can edit that, don’t worry. Got a Spin Free Kit up front. So next, now it’s up. Next time, we’ll make it look better. Yeah, we will. We’ve got a whole list of stuff to cover. Lists. Lists of stuff. *snap* We’re out. You can say cut again. You like doing that. That’s a wrap. He likes doing that.
