Oh nevermind, I found it in the thread. I've been reading this religiously trying to get pumped up for a new carrier and must have over looked it. Thanks for the help.

http://www.superioraxlegear.com/3520...l-p-10203.html

If I just buy this kit from superior, would I still need to buy the bearings? It says that it includes carrier bearings and I'm assuming that's the same thing. Am I wrong about that?

Yep, I used the shims from the D30 kit because they fit the D35 just as well. For that kit you linked to, that seems to have the correct carrier bearings, so, no, you wouldn't need to buy additional carrier bearings; however, you'd end up paying for pinion bearings in that kit that you don't need. Maybe you could sell those here, but I think you are better off just buying the carrier bearings separately and buying the cheaper, no-bearings Dana 30 install kit like I did, and using those shims on the Dana 35 carrier. They fit perfectly. (I knew they would because a tech told me they would.)

Don't buy direct from Superior; they charge more, to protect their dealers, and will tell you so!
My first time buying Superior gears but they look excellent and Made in USA!
Nice people at Northridge, and they knew exactly what I needed to get-er-done!

In the past, I have always used Randy's Ring and Pinion and Yukon Gears.
But Yukon 4.56 gears are back ordered for the Dana 30 until January???
Aussie Lockers for D30 are also impossible to find?? Dave at Northridge sold the Spartan for the Aussie price!

Note: Superiors Install Kit for D30 did not include axle seals??

I have not. There are a several threads on TrueTracs and snow, and front lockers and snow. I'd have to refer you there.

In my experience, dual truetracs are awesome in the snow .

For the life of me I can't figure out how I've missed your thread(s) for this long? To read your scribbles is an absolute pleasure for me, just as Stu's write-ups are. Maybe it's an old man thing, eh? Yeah, I don't know either...Anyway, nice job, well done and a well deserved pat-on-the-back, FarmerinVA!

EDIT: I know how I missed this thread, I was chasing a dream down south, had no internet access or anything really outside of a radio & DVD from July through mid Sept. Either that, or my memory is far worse than I thought...ah man, say it isn't so...

I just wanted to thank you for making this thread. My D35 recently went south on me when all the ring bolts backed out and half sheared off. Needless to say I needed a new carrier and decided to install an eaton true-trac. Everything I read on the internet made me believe I needed my mechanic to do the install until I found this thread so thank you for all your help.

Amazing, amazing write up. Not sure which is more impressive, the work or the thread. I was faced with exactly your situation and ended up doing "almost exactly" what you did - except I got into the D35 and decided to solve with a few hundred $$ and I also did the CCE rear axle. Had this thread been around while I was struggling with the TT, I probably would have kept going. Nice job.

Thanks, gents (or gals). I'm glad someone actually read it. Given all the work, reading, garage talking and time I had to put in to learn all this, it seemed a shame to just let it rot in my head. It was sort of like buying a diamond ring: a whole lot of learning and expense, which seemed silly if the whole point is never to do it again.

I still haven't gotten a good video of the TrueTrac working. The problem, paradoxically, is that it works too well. You can't tell when it engages because it has a smooth take-up, and it does let the wheels spin at slightly different rates in mud (depending), so it's not clear to the observer that it's making a difference. But it sure does make a difference. I'll make a better effort on the video sometime in the spring when it warms up.

Ive been super impressed with the truetracs performance so far. In the rear, when accompanied by a front locker, it works 95% as well as a locker as long as you dont lift a tire. Typically I lift front tires not rear anyway. I can only think of one time Ive had a rear off and it was on a sharp decline and I was engine breaking in 1st/low.

Its fawesome in the snow as well, even with an aussie up front.

Why did you have to set the backlash in the rear and not the front?

Because in the front, I did not disturb the ring gear, shims, or bearings, the way I did in the rear; in other words, I did not change the backlash of the system in the front. Whatever backlash it originally had when I pulled it out, it still had the same when I put it back in. That's one reason why lunchbox lockers are so popular -- no need to mess with bearings, backlash, etc.

Backlash is a description of what's happening where the ring gear and pinion gear meet, but it's controlled (assuming your pinion gear is at the correct depth) simply by the side-to-side positioning of the carrier, which you adjust using shims.* I did change the side-to-side positioning of the rear, due to the fact that I installed a whole new carrier. I didn't in the front.

* Some carriers, such as some of the newer Ford axles, use a screw system instead of shims. But TJ stock axles use shims.

IF you go to 4x4GroupBuy you can get Superior Front and rear gear sets and front and rear master install kits for $500 total. Thats what I did. I did have Motive 4.88's but sold them to a buddy when I got hit by granny cause I knew a HP d30 was going to go into the Tj instead of the LP d30.

Also you can use your old bearings that your going to replace for setup bearings. Just use a Dremel or Die Grinder and take enough material off them so that they are easier to put on and off.

One more thing: If your going to put an E-locker or any of the Super Kits then more than likely the carrier bearings/races from the master install kits wont work. The journal diameter is larger on these items.

Since this thread turned into something of a resource thread about TrueTracs, I thought I should re-post something from IslandTJ today in another thread. He has TrueTracs front and rear.

It was a bad wheeling day, turning into night. The snow was deep, slick and falling heavily with rain. I was anchoring a group and on the last trail that we were on, 2 Jeeps in front of me got stuck and required winching. One of the Jeeps couldn't start back up and required to be towed back down to the forest service road.

With a come-a-long and the downed Jeep's winch, we slowly turned the dead Jeep around 180║. When I attempted to pull and drag the dead Jeep down the trail, I managed to slam my front tire into a cut tree stump sticking out of the ground (it was originally hidden by the snow). The force was hard enough to unseat the tire's bead. LOL I didn't know I lost my bead, I just thought I screwed up my front TrueTrac because I suddenly lost a lot of traction.

By this time another Jeep came up to help and proceeded to pull the dead Jeep down the trail while I went back to winch out another Jeep. After the Jeep was extracted we turned around and proceeded to drive back down the trail. While making our descent, the Jeep in back of me noticed a tire on the side of the trail and commented that she did not see that tire when we drove up earlier during the day. 5 minutes later when I made a sharp right turn, the Jeep in back of me saw my exposed wheel shining brightly in her lights.

It was a bad night... I had to hike back up in the snow and water to get my missing tire back.

On a good note, my tire was warrantied and I got new KM2s for the Jeep (ran KM1s for the longest time) .
Holy cow. If that's not an endorsement for the TrueTrac, what is? Even with him totally missing a tire, in snow on a mountain, he was still getting some use out of his other front tire, and he was still able to limp out of a situation that got other Jeeps stuck and he didn't even realize he was missing a tire until somebody told him.

Try that with two open differentials.
