"OLD SCHOOL" manual hubs

[ShadowsPapa]

?? To Lockers but that's only on the Rubicon, and Power Wagon and Ford Raptor from the Factory.
My point was "OPEN" differentials are useless no way should they be "STANDARD" equipment on a 4x4 vehicle.
? I do remember in the "1990's" the full size Ford Broncos and F-150's with the twin traction beam front axle were available with a "FACTORY" Limited slip "FRONT" differential as on option...
Once again it's a 4x4 shouldn't both differentials be at the very least Limited Slip ????

Worthless? Have you seen the videos I've posted of Eagles doing Moab's big rock formations rock crawling, going through deep snow and so on?
TWO open differentials. They never even had limited slip as an option.
Mine goes crazy good in the snow. I never had my 84 wagon stuck until I high-centered it messing around after a blizzard on my farm in snow that was waist high in spots. I could drive the speed limit on unplowed roads that had snow bumper high.

How "old skool" are you really? If you really are, you know how capable a 4x4 can be with the right tires and a good transfer case. Not everyone is doing the rubicon or Moab's wet rocks.
I'd bet most of the JTs sold in the midwest don't have LSD.
If I am correct, limited slip wasn't even an option for the first Sport max tow JTs. There's thousands of them out there without it - are they bitchen?

Not everyone buys a 4x4 to crawl up the walls of the Grand Canyon.

Amazing how some folks believe that their desire should apply to everyone.

My rubicon is open until I lock it and the places I go, I go with unimogs, also open until locked.

Honestly - can you do a lot without locking it?

 

[ACAD_Cowboy]

Honestly I only use the locks when I fighting either slip because rock slime, skree etc or it's rock garden wheels in space action. Other than that it's open and just jumping between hi and lo as needed.

Ultimatly I always get to a point on the massmog trails where it's just easier to leave it in low and hop between 1-2, 3-4 or 5-6 depending on how open the trail is and then perhaps I locker, maybe because of slippies.

If you can brake lock a diff you ARE the LSD at that point.

So to answer your question, yes. And for the bonus adventure points I often go out on the beach in 2wd like a VW because I air down to like 8 and float on by.

I have "NO IDEA" what's really going on in this "THREAD" other than some random "BLOATING" and arguing over "TECHNOLOGY" by a poster that has "NO IDEA" what he's really talking about.

That's what we've been finding out - when I don't plow our driveway, I've found modern vehicles will work traction control (which is based in ABS) and "walk" right up the drive through the snow.

I can't wait to visit my son in Florida and see if there are any places we can take my truck onto the sand (or is that into the sand - hopefully ONTO.....)

Correction - you have it figured out

Did you have a Ford with the automatic hubs where you had to back up etc to lock and unlock?
Not a vacuum system but like manual hubs only automatic. Had one fail when my wife needed the truck for an appointment and I was out of state. She was irate and that truck got manual hubs on it as soon as I could order and install them. Warn....nice hubs.

Funny you say that as My 87 full size Jimmy had the factory "auto" locking hubs" and you were supposed to back up to disengage them after throwing lever to back to 2H. I couldn't wait to get that home before I changed to the Warn premium hubs.
All the S10 series of trucks had the horrid vacuum disconnect system too. My son's 2005 ZR2 blazer has it and I've really thought about swapping out the CAD for the Oldsmobile Bravada system.

A good computer controlled AWD system can do a lot of cool things and do it better than I can based on the ability to see very small changes in very short time intervals. Crazy Larry who runs with me does the same trails in a land rover sport with knobbies and it's more about line and patience than gear and tech. He and I will watch the big trucks rumble and snort and plan our lines of attack. I'll have to see if I recorded it but there is a wet/dry stream bed we go up, steep with mud, skree and watermelon sized rocks randomly scattered. I did it in 1st lo with no throttle the whole way, just idle crawled it for a half mile.

I converted my '97 Ranger to Warn's manual hubs, the "automatic" hubs blew out twice in 33K miles. I drove thousands of miles with hubs locked and unlocked, there was no measurable difference in mileage. There was a measurable difference in performance when I stopped to pull a UPS truck out of the mud on the side of the road, and my truck was 2WD only!

The miniscule mileage improvements are cumulative and important to regulators, not in the real world. Ford switched to full synthetic gear oil for trucks in the late '90's, claiming .15 MPG improvement from that. Invisible to us, but not to the EPA.

My YJ still has the original fully functional vacuum FAD, which when it dies will be replaced with a TJ axle. Until then.....

Back in "1986" a co-worker bought a CJ-7 it had manual hubs, he stated the owners manual recommended a brake in period to drive in 2 wheel drive with hubs locked and if you anticipated possibly having to shift into 4 wheel drive you could drive in 2wd with hubs locked

 

[brianinca]

Sealed unit bearings are AWFUL, I totally agree!

To me the benefit of manual hubs isn't the wear on the drivetrain, it's the serviceability at the wheels. Most of those setups are a traditional 2-bearing hub setup instead of the sealed unit Jeeps currently have and carrying a set of bearings and a seal is a lot easier than a new hub (or two if they're different).

The benefit from drag is minimal and even wear is negligible since there's no load but I'm just a fan of being able to actually fix shit instead of just replacing entire assemblies.

After getting my Ranger back from the body shop where insurance would NOT let them replace the t-case after the rear driveshaft was ripped off, we went woodcutting at the ranch.

Ford has had a dial to engage the transfer case on various trucks for a long time, which controls the electric motor that changes the transfer case modes.

The case would NOT engage 4Lo, so I had to head up a steep hill WAY TOO FAST to get where we were going. I was pissed. I could have disassembled the motor linkage and manually forced it into 2Lo (probably) but by that point my new paint already had a full set of manzanita stripes, so eff that. I didn't want to belly down in red mud anyway!

I'll take a manual shifter ANY DAY and twice on Sunday!

Let me elaborate Solid front axle heavy duty would the Jeep "FAITH-FULL" accept "I.F.S." On a Wrangler or Gladiator
The 4 wheel drive Transfer case "FLOOR" Lever operated
Would the truly hard core Jeep "FAITH-FULL" condone a dash mounted switch to engage 4 wheel drive.
isn't at the very least a floor activated transfer case more reliable than a push button or selecter switch ??

It does seem odd that they chose to go the axle disconnect route. 05+ Super Duty 60 vacuum/manual hubs seem to have an excellent reputation. Maybe it would have been too difficult to adapt that to fit in a smaller 5 lug hub. The axle disconnect is the only thing that really concerns me about the JT as far as long term drivetrain durability.

And yet there are thousands of vehicles with that system in place, still working, decades and hundreds of thousands of miles later...........

Yes - size matters with the Jeep hubs, a lot smaller than what I had on my F250 - those hubs were huge compared to these.

One always hears of the failures or break downs - that's the internet.

Dang lazy Americans! Why can’t I have a manual choke lever on my dashboard anymore? And where’s my fuel mixture adjuster??
