Glad you enjoyed it!

I agree

+Corey Henton I do not know about way too long, but it is long.

You guys must think your order at McDonald's takes too long too.

looks fucking good tho

I agree it's necessarily long for KZfaq.

I'll put it on the list

GlockUSMC how big of tires are you running, also what motor does your ZJ have?

Take the cover off & push it out with a heavy wire or flexible rod.

bending moment too

No shear. Load-carrying applies strictly a bending moment to the axle shaft. The load of the vehicle is carried at the very end of the axle shaft, but the bearing is a few inches inboard of that location. Think of the axle as a lever with the bearing being the fulcrum. One end of the lever is very long and needs very little force applied at the end to make all forces balance (that's the end that splines into the differential side gear). The other end of the lever is very short and thus is subject to much greater stress (that section between the bearing and the axle flange which the wheel is bolted to, and using the crowbar analogy, this is the part where the crowbar does its job, so you can visualize how much greater the bending stress is there). In actual fact, the bending stress is the same at any given distance of both sides of the bearing, but it decreases rapidly with distance from the bearing, so most of the inboard section of the shaft is NOT under much bending stress.

He addressed that, he said NASCAR has been using full floating axles for a long time. That way if an axle breaks, you don't have the wheel separating from the car with the centrifical force.

+Bailey Ferguson I really doubt that would work as they wouldnt fit properly and the CV is machined to hold the boot on. Besides, U-joints dont need any protection from mud or debris... Any covering would just hold water.

+BleepinJeep oh ok... thanks for reply but I thought it would kinda.

+Kico Horvat They use solid rear axles

+BleepinJeep Why?Independante rear axles are better i think for high performance cars.

+Kico Horvat because Nascar is a knife fight...not a fencing match.

Apparently the little WWII Willys Jeeps use them as well.

I have an 83 FJ60 and it is Full float. This I learned as I searched for a bearing kit. Nice to know

yes

+Jeff Young Yes but shorter due to the u-joint/CV and the outer shaft and brakes width. Only the "inner" is full float. But if you think about it, so is an outer shaft. Because of this 2 piece design and shorter widths with angle between, the u-joint is the weak point in the front. A CV is stronger than an outer. Happy Jeeping!

can Anyone explain carden joints ? That's what older four wheel drives had on their front axle prior to the late 70s. And the wheel bearings floated in oil. They were not packed in Grease.

@@frankpaya690 A Cardan joint is two standard cross joints mounted in series, but 90 degrees out of phase, with a central ball and shaft that maintains alignment (keeps the joint from "flopping around" since it's a double joint and therefore not self-supporting against side loads). This way, the variation in rotational speed of the driven side versus the driving side gets cancelled out across the full length of the joint. Only the center portion of the joint has a rotational speed that varies, but there's no ill effect from that. Note, the variation in rotational speed of a standard cross joint only occurs when the joint is "bent", and increases (becomes a more severe problem) as the amount of deflection increases. For a typical driveshaft, the cross joints at each end are directly out of phase, and the angles of deflection are roughly the same (or should be), so the whole driveshaft works just like a Cardan joint, with the central portion (the actual shaft) varying in rotational speed with each full rotation, but the two ends driving and driven shafts at each end both spinning at constant speed. Sorry that's so long. For what it's worth, I've never seen a Cardan joint on the steering knuckle of the front axle of any light-duty 4x4 (nor have I seen any with oiled front wheel bearings). There were plenty that used Tracta joints (like Dodge Power Wagons after WWII), and I've heard of some older light trucks (some "almost-medium-duty" IHCs) using a Bendix-Wiess joint. Both of these are constant-velocity joints, like a Cardan joint is, but they work in very different ways. I HAVE seen Cardan joints at the knuckles of heavy-duty Marmon-Herrington front axles.

+fordwindsor351 cool story bro

+Ron Matheson If only they were mine....Unfortunately the 14 bolt and the D60 are my cousin's. :(

+Tyler Bleepinjeep do you know why matt didn't go with fullwidth axles (60/14bolt) for his crawler build?

+Charley Williams He wants to stay as light and narrow as he can. It works better for him on the terrain he normally wheels.

I second this comment. Thank you
