Man these manual hubs sound like a pain in the ass! What’s the hype all about on these? They just sound more inconvenient than they are worth

Time will tell, but the benefits i.hope to realize
1. CVs don't spin when unlocked, reducing drag and wear on parts, boots, front diff, etc. (handy when front is lifted 3" or more to reduce boot wear/failure)
3. Front wheel bearings are internally pre-loaded, not relying on CVs, you can drive without CV axles installed*
4. CVs don't need to be repaired or replaced on the trail if broken, you can unlock a hub and go (assuming you can manage without 4WD)
5. Improved mpg with hubs unlocked (debatable/tbd)

I'm not changing anything else, llike removing ADD, so I can lock the hubs anytime I want and the truck behaves like it cale from the factory.

*Obviously you'd have to plug the front diff axle holes to drive without CVs, I'm not looking at this as an option I would exercise.

I'm keeping all my old stuff so if I have it I can always switch back.

I only went manual hub option myself only for simplicity of the system. I did a 4x4 conversion. SO manual hub and j-shift style T case avoided the nightmare of setting up the vacuum and electrical side of the ADD system. I hate getting out in the snow and rain to engage or worse disengage my muddy hubs. I'm running manual hubs and going through the pains of doing so without the benefit of a solid axle haha...but I have a 4x4 now so I'm stoked.

Octane is correct that CV's don't spin when not engaged at both ends so less wear which means they should in theory last longer then ADD rigs put under the same driving conditions.

I have also run in 3wd when one of my CV's was damaged on the trail and needed to get to a spot where I could swap it out safely. Obviously the T case side was engaged but wheel side wasn't and the wheel side joint is what I had damaged. Did it prevent the CV from fully failing while pushing through the trail to get to safety? Whose to say?

Glendale AZ. Just stay away from Metro Center mall and Cripttown (Christown) mall. Your runner will not leave in one piece.

Went to Lake Arrowhead this weekend and ran 3N34 to 3N34D this weekend as a shakedown/break-in run of the new 4.88 gears.

Rear 3rd member was pre seasoned by @Airdog so no break-in was required, but the front diff came from ECGS with new 4.88 gears, a solid pinion spacer and a Spartan locker.

Lucas 85W 140 in both diffs and took it easy using 4Hi and Lo really just to do so, most of the trail was 2WD possible,.until this point

My clutch master was not holding pressure well requiring me to double clutch most shifts and I didn't want to over work the new gears so we had lunch at the top and headed back when it started to rain

On the way back we came up on a Land Cruiser that rolled a bead, a dad and two teenage girls. They were lacking tools (like a breaker bar and jack) and dad was struggling alone so I helped him change out his tire and made sure he got back to pavement safely.

Went back out the next day, exploring a trailhead from the Marina I didn't know existed, it got us to this 3-way junction

The middle trail leads to the trailhead behind our house, so now we have 3 ways to get to 173 if necessary

Still have 2 more break in runs to do, then dump the front diff fluid and refill with fresh 85W 140

Changed out the clutch master last night with CMT-093, l good now

Cool trip! I envy the off-road opportunities you have out west.
