TeraFlex Install: Full Float/Locking Hub Conversion Kit

The TeraFlex JK front locking hub conversion kit is designed to upgrade JK Dana 30 and 44 axles, while the rear full float conversion kit will add some serious strength to your JK Dana 44.
SlimLock hubs feature 4340 chromoloy 35 spline stub shafts, and Dana 60 components throughout.
The rear conversion kit utilizes a two bearing design to evenly spread the load, allowing the 4140 chromoly shafts to simply transfer the torque.

I dont even have a jeep and this video makes me want these. This is such a well done install video.

[@harrygatto]

Very professionally done and with excellent, informative narration. One of the best presentations I've see on YT in a very long time.

[@vt3fan4evr]

not 100% professional. all this new gear including new rotors yet he put old pads on those new rotors... if your spending that much on this but are too cheap to put new pads in the end... thats not professional. if i did this for a customer they would be back real quick.

[@kevinhornbuckle]

Excellent video. It makes me wish I had a Jeep again.

[@WanderOverlanders]

This brought back memories of my old 1978 full time 4x4 Chevy Silverado. After hunting trips where I ended up crossing river crossing I would take the front hubs off and repack the bearings. The technology here is not new, I would go through the same steps here. Remember that was in 1978.

[@DaveKaiserIII]

With excellent how-to like this I will buy more parts!

[@SpacemanFan1988]

Another amazing product by Teraflex and an amazing narration by Dennis Wood. Edutainment and funny.

[@teraflexsuspensions]

Edutainment...hahah thanks Dennis

[@SpacemanFan1988]

I would love to see something for the Jeep Liberty. There is such a small amount of lift support and a true rear four link conversion would be amazing to see.

[@Trump985]

Looks like another great product and very easy to install! I wish they had a 5 lug hub version I would rather not have to get a new set of wheels but it’s a good excuse to try some internal beadlock hummer wheels!

[@NEWEREJK]

Does this upgrade change the axle's wheel mounting surface distance? (I see bellow it stays the same.) Any suggestion on the new 8 lug pattern matching the TeraFlex HD Carrier lugs? Will this work with TeraFlex's JK High Steer Sys. & Drag Link Flip kits? JK Flat towing... requires front hubs locked or unlocked? I was told a front drive shaft is required to flat tow to keep things lubed in the T-case. This true... Y/N?

[@lelandeggleston1041]

Because of these kinds of videos I see no reason to buy another brand for my jeep upgrades. Good work.

[@MrRebTyree]

Awesome video as always!!! Well done, very interesting and informative video!!! I would love to do this conversation to my 2011 JKU 4 Dr with the 3.8 engine

I use the vice and a socket to press the caps back in, instead of a hammer. Nice and easy, and make sure it goes on smooth.

[@72xafalcon]

I love the way the guy/mechanic?/butcher wailed on the new uni joints with a hammer when he could have/ should have used the vice to press them in, I've seen guys crack the cups using a hammer to get them in

[@ntaft0904]

This was a well put together video and excellent job on narration. I was thinking the same thing about the brake pads when I saw the old ones go back on. I too wondered about the convertion to the 8 lug wheels. I guess depending on the utilisation of your jeep the justification for more strength can be made. I really don't see that the wheel lugs as a common fail point for most. I would be interested in the conversion to locking hubs and bigger brakes. Anyway like I said though this was a very well put together how to video. One of the best I have seen.

[@teraflexsuspensions]

Thanks, we have reprimanded Dennis for not using new pads. It will not happen again 😂.

[@ntaft0904]

TeraFlexSuspensions I didn’t know if the reprimand was necessary after all it’s a 4x4. In my earlier days when I was more of a hard core wheeler I used to do a lot of sandy water crossings. If I had replaced my brakes every time I took things apart to clean all the sand and dirt out of my brakes I would have spent a fortune. That was the whole reason for taking things apart was to get more life out of the brakes. Learned that lesson the hard way. Lol

I am not a mechanic so please be patient if this is a silly question.. With a full float axle and the jeep in 4 x4 with the axles UNLOCKED does this mean they will spin independently of the transfer case even if engaged.

[@stevejobs1349]

Dennis and Teraflex I just installed the full floater kit and followed your directions exactly and backed up the spindle nut as per instructions. The wheels spins freely however my first drive in a hot day the front hubs were really hot. Is that normal will the bearings will settle down or should I do something

[@gwot]

RED thread lock on brake bracket?! good luck with that

[@pauljanssen2624]

I used to do that that's old-fashioned way for floating hub just have a bottle of high-quality gear lube and filled the hubs and then slide the last bearing in i turn the hubs and no need for packing the bearings make sure you get your preload on the bearings right over tight not good and loose not good

[@theoriginalwunfeather9168]

I have a TJ on Dana 60's with 15x10 inch 8 on 6.5 3 inch BS and I ground the calipers just a bit to fit. Can I run a small back space 15 inch steel wheel with this upgrade? If so, I am going to do it. I like 15 inch wheels and 38 inch iroks. More tire more flex.

Will this kit fit the Dynatrac PR60 semi float rear axle? It seems like as long as the spindle has the correct OD dimensions it’s be gtg. I really need to know lest I perish!

[@teraflexsuspensions]

Yup, as long as the spline counts match and the tubing diameters match. The Spindle has a Outer diameter of ~2.64 for a slip fit. Double check with Dynatrac for tube ID.

[@akltom]

new rotors with old brake pads... great match😑

[@675daytonarider]

How much strength does this kit add to the front vs say RCVs and is there any way to get the front kit with RCV outers? No longer have stock shafts.

[@teraflexsuspensions]

There are 2 forces on the axle shafts and carrier with a semi float, a load from the weight of the vehicle, and load from rotational force. By supporting the shaft with 2 bearings on a spindle, you are eliminating the forces from the weight of the vehicle. Now the only force on the shaft and carrier is rotational force. Huge increase.

[@jakestech28]

Full floating axles should be a standard on Jeeps and mid sized trucks, most heavy duty Trucks have them. Why not smaller trucks and Jeeps?

[@teraflexsuspensions]

Good question! Probably helps to keep the cost down.

Am I missing something? Why are you drilling holes in the rear axle, only to weld them back up?

[@johnfleury5430]

Not greaseble ujoints? What the cost of all that shiny iron White grease in the locking hubs in cold country would be recommended

[@gamer78full]

Greasable u joints are a little weaker, that’s why these kits usually come with normal joints.

[@RobWillmot]

Dont you think 135 F/Lb is a little exsecive for a 9/16 nut. It should be about 80 F/Lb

[@TomKirkman1]

I'd love to have free wheeling hubs on my JK, but why did they choose to change up the 6 lug set-up? This means that unless you do the rear as well, you will be running two different lug-bolt/pattern wheels and can't rotate your tires. Furthermore, you are going to have to buy at least two new wheels even if you only do the front. This doesn't make sense.

[@teraflexsuspensions]

Unfortunately you can't fit a wheel hub this diameter into a stock 5X5 bolt pattern on a JK, there just isn't room. You have to go to a wider 8x6.5 to fit all components. Any yes, usually one would either buy both front and rear conversions. If swapping an axle to a 60, that comes stock with 8x6.5, some choose to add a conversion kit to their other axle instead of swapping both at the same time. Tons of options out there.

[@graemelliott3942]

Used brake pads?

[@DavidWright-yh8zx]

New rotors old pads ? Saving cash uh!

[@teraflexsuspensions]

Standard braking systems use 70-80% of their braking in the front and 20-30% in the rear. To achieve even braking, we were able to get that by increasing the diameter and surface area on the rotor. Overpowering the rear brakes will spell disaster.

[@robertpoet1665]

Old pads won't properly seat to new rotors, resulting in blue hard spots and brake pulse. You're buying an expensive upgrade for your ride, why cheap out on what could easily become a safety issue? Pads are dirt cheap. Change 'em out!

[@65BAJA]

Does this change the track width at all? Asking after the JK Rubicon rear application.

[@teraflexsuspensions]

No, it will stay the same.

[@rockyour4x4]

Is there a 35 spline rear shaft option?

[@teraflexsuspensions]

That's what I wanted to know!! I checked with engineering explaining that I had needs ( they didn't seem impressed); I want to run 35 spline shafts in my new SEMA build. They are going to try to make it happen, its just a matter of cutting down some shafts. Right now we only have them for 70 wide axles... Will advise Dennis

[@rockyour4x4]

+TeraFlexSuspensions thanks brother, I be Rollin an 80, but every built 44 I do has 35 spline shafts

I'm not very informed on axles talk, but what advantage does having locking hubs serve?

[@teraflexsuspensions]

Great question... 1. Wheel bearing load is spread out = no more unit bearing failures. 2. Increased fuel mileage. We are no longer turning axles, gears, and drive shafts. 3. Which brings me to the joys of no longer having to worry about front driveline failure at freeway speeds.

[@teraflexsuspensions]

We recommend the total backspacing be 4.5" or less. So a backspacing of 4.5" and 0 offset of a negative offset.

[@stevejobs1349]

Currently I am running 5.75 back spacing with +18mm offset using Teraflex big brake kit on stock axles with 35” tires and 3.5” lift and it clears perfectly and I am ordering Tera 44/60 with full float with stock width axles you think 5.75 back spacing will work with +18 mm offset exactly same what I am using ? I am afraid 4.5 backspacing will make tired stick out of fender flares ?

[@teraflexsuspensions]

5.75 backspacing plus another ~.70 inches is the wrong direction. You will end up around 6.45". You need to be less than 4.5" to properly clear your steering components/frame, and recenter your Center of Gravity. Unfortunately that combo will not work.

Thats sweet and all but the internals are still the same internals lol dont get me wrong they can handle some shit but theyre not no 3/4 axle lol but yeah i like the locking hub idea thats always nice to have with jeep-dodge shit ...

[@jcvince17]

What made you all go 8 on 6.5" bolt pattern instead of sticking with JK 5 on 5" or 5 on 5.5" like the other kit available on the market?

[@teraflexsuspensions]

That, little buddy, is a Great question. When we were looking a doing the conversion, it was necessary to go from a 5 0n 5 bolt pattern to a 5 on 5.5 pattern. No way around it, you were going to need to buy new wheels. If you are buying wheels anyway why not buy 8 on 6.5 and gain all the strength advantages. The 8 lug also allowed us to use off the shelf 1 ton wheel bearings etc. Much stronger alternative.. Dennis
