Front lockouts or Yukon spin free hubs discussion

I had not noticed this thread until this morning. It reminded me of when I was researching manual hub kits in 2018.
https://wranglertjforum.com/threads/advice-needed-choosing-a-manual-locking-hub-conversion-kit.16093/

Milemarker had a kit using AVM hubs manufactured in Brasil, so did Rugged Ridge, but comments about the hubs on the various boards weren't particularly positive. Another guy known as the "Ram Man" also marketed a kit using AVM hubs and a modified Timken unit bearing, but he came across in his promotional videos as a snake oil salesman so his kit was off my list as well. At least one of the suppliers recommended a maximum tire size of 33" with AVM hubs and Randy's/Yukon had no positive comments about them. I decided to stay away from kits using AVM hubs because I run 35" tires. How ironic that 5 years later Yukon is using AVM hubs.

I purchased the Yukon 5x5.5 manual hub kit (YU-WA-08) on Amazon, sale price $1,078.41. Black Magic 16" brakes were installed at the same time. I sold my 5x4.5" wheels and purchased a new set of 5x5.5" wheels, but re-mounted my existing Mickey Thompson 35" tires. A few months later I was able to purchase a pair of spare Yukon hubs, bearings, seals, etc. from a board member at a good price.

I have not experienced any negative issues with my Yukon hub 5x5.5 hub kit, have not yet needed any of the spare parts, and would make the same decision again.

I'm running the same setup (including the brakes) and have been very happy with it as well.

Broke my last Warn 37780 hub over the weekend. I installed the AVM 465XP hub. I guess I'll see how this holds up or should I say how my shafts hold up.

@mrblaine, have you had any more experience on these AVM hubs since we last interacted on this thread?
 
I’ve been running these AVM 465XP hubs for about a year now, and they hold up well, maybe a little too well. Ive managed to break my outer. Wheels straight and up in the air on throttle. Snapped on the landing. Luckily, it didn’t take out the spindle, only the needle bearing got damaged, however, I think it broke my Detroit locker, it’s been stuck locked, I’ve yet to disassemble the locker to find out.

That angled fracture at the end of the shaft is the problem child. We've seen that with the yoke intact which then spins those two ends past each other which blows up the spindle and bearing. That's when it gets expensive. We've been around a lot of Detroit that quit working after a shock load. They don't like them much.

I've been told this too by some other folks, that is how that stub breaks. I meant to say that my spindle is saved, only the needle bearing broke, but yet to find out about the detroit. I've heard that the yukon's grizzly handles those shock load better and survives?

This is what I'm worried about. I want the hub to break not the shaft. I was lucky when the stub shaft broke last time that it didn't take out the spindle.
 
Hello everyone,

I'm planning to install a YA WU-07 Yukon manual locking hub kit on my 2005 TJ Rubicon.

I understand that the kit widens the front axle by almost 1" per side, so I’d like to install rear wheel spacers to match the track width. I know hub-centric spacers are recommended — any advice on a good brand or model?

Has anyone tried these I found on Amazon?

Regards

Mariano

Your wheel studs are 1/2-20, the Amazon spacers have 14mm or roughly the same as 9/16". I don't know that I would do it that way.

According to the Yukon site, the 5x4.5 kit widens the front by 3/4" per side. I've been going round and round looking for wheels that fit similarly to my JLR wheels and spacer setup i'm currently running, which equates to a 3.5" backspacing. If I end up going the route of the spin free kit, which I am leaning towards, I will probably find a lug centric 1.25" spacer adapter to run the JLR 5x5 wheels. I am not opposed to going the 5x5.5" route as my axles are dual drilled, but not sure (haven't looked) if there is a 5x5.5 rear disc brake rotor that would work, or if i would need to drill them out myself.

Yukon can't read a digital caliper.

That will be a cute trick given the diameter of the locking hub snout.

Currie may have them. Easier to drill yourself.

Re: running JLR wheels, I was referring to using the 5x4.5 kit. If I went 5x5.5 I’d go aftermarket wheels most likely.

Do JL wheels have a larger center hole than my JK wheels did when I installed the 5x4.5?

even the 5x4.5 hub will be larger than the center bore on any factory JL wheel. Some have made the additional clearance with a holesaw. I would probably farm it out to a machine shop as I'm more likely to screw up a wheel.

As soon as I get the kit, and after checking whether Yukon sent any wrong or missing parts, I’ll take the same picture to show the current hub size and the brand of the locking hubs they shipped (hopefully not the red AVM 🤮).

The only way you are getting Warn hubs is if you find some old stock. They haven't been shipping the Warns for about 2 years now.

Theres another poster that has the yukon kit with JL wheels and has posted a how-to on it. The JL wheels are the same center bore, but also like the JK wheels, they are smaller where the center cap snaps in, which has to be corrected (machined, drilled, ground out). I am prepared to do it to either my JLR wheels, or swap the tires over to a set of JK moab wheels i only paid $100 for 5 of them. The lug centric spacer adapters seem to be the hardest piece of the puzzle to find, but not impossible.

If it was mentioned and I missed it, don't overlook that the 5.5 hub kit doesn't add any track width.
