Got a little topless time in today.

Can you engage the rear locker in 2 wheel drive? I could not until I did a modification on the Titan. It was set up from the factory to only engage while in 4 Low. The mod I did now allows it to be engage in any gear, 2 wheel, 4 high, or 4 low.

Chris

The rubicon it set up to only engage when in 4x4. Don't know it is did it in high or just low. With a modification you can engage the lockers when you want front or rear.

I put a set of rubicon axles in my TJ. Have the vacuum pumps wired on seperate switches on the console with a master switch under the 4x4 lever. They way you can't accidently engage a locker.

So they use a air locker? My Titan has electric lockers. I was told they are Dana Axles and Detroit Lockers but to be honest I am not 100% sure.

Kinda, but they were the original's. Well, from what I have read and seen, Bantam was, but...

Dad's was the Ford war production version; Willy's, like many other companies, could not keep up war production. Ford built tons of Jeeps during WWII. It had the frame mount for a 50 cal, and the bracing ect on the dash for a 30 cal mount. Also had the ammo lockers in the rear fender wells. And, a couple bullet holes... Although it was doubtful it was ever in combat; probably stayed Stateside for training ect.

That, and the CJ5(my Dad had, and I later bought back from the guy he sold it to) were fun, because we could fit where newer rigs cant. The later CJ's('77 and up) thru the new rigs are wider for road stability.

Buddy of mine has a newer Jeep; it is amazing how the new ones with coil suspension can articulate. Even if you discount lockers, just the suspension articulation will keep tires on the ground where they can get traction.

Sounds like the Suzuki Samaria my HS buddy had. That thing was unstoppable.

Yep the ones in the TJ's use a vacuum. Just a single rubber hose run beside the vent tube that connects to the pumpkin. Don't know about the new JK's but assume they are the same set up.

Same principle as the auto hubs on the Fords. They run off of a vacuum.

Gotcha, thanks. I knew there were air lockers, just did not know who used them.

Yea, I have had many of them Fords. Never had a single issue but it seem many do. I use my 4x4 weekly and never had a single issue other than a failed transfer case in a 89 Blazer. It always seems people who have issues with 4 wheel drive never use it then when needed it does not want to work. For that matter my father or BIL never had any issues either in probably 25 Fords in the last 15 years...

I have a vacuum leak on my F250's 4x4 at the moment. Think it might be an O ring on the hub. The auto hubs are great when they work and very expensive to replace.

Actually the TJ Rubicon models with front and rear lockers run off air pressure. Each axle has it's own little electric activated air pump. The hose is the pressure line going into the locker. i believe they use 5 psi but don't quote me on that, I've never checked the pressure.

They are designed with several restrictions in place. Can't activate at speed. Can't activate the front without first activating the rear. Etc., etc. But all that can be overcome with minimal electrical knowledge.

Anytime there is a discussion about Jeeps someone always jumps in to talk about some old CJ or Flattie or WWII Jeep they were around years ago and how great it was and that it would go anywhere.

Kinda like me when I talk about my first new car, 1969 Mustang. In my memory it's the fastest, best handling car I've ever had. Sure wish I had it today....... If the car God dropped one in my driveway today I'd first take a hot lap,,,, then I'd pull it in my shop and start modifying it so it would steer better, ride better, stop better, go faster...... I'd realize quickly that my 40 year old memories are a LOT better than the car actually was.

Our oldest Jeep is a 1953 M38A1, next is a 1970 Jeepster Commando, then CJ, FSJ GW, YJ, TJ with the newest being an '05 TJ Sport. This fleet's offroad abilities are directly related to their age. The newer the better. Other than my homemade stuff, most capable being the '04 TJ Rubicon.

A lot of trails were blazed with the old Flatties and early CJs. But not without a lot of manual labor and at an extremely slow pace. And those early trails blazed a bypass trail around the most difficult obstacles. Now the trail goes to and looks for the most difficult obstacles. Those old Jeeps simply were not very capable offroad. In their day they were because no one else made anything to compete with them. But when compared to today's Jeeps,,,,, no race. But it's fun to imagine in our memories!!!! :laughing:

I got confused. Remembered buying vacuum hose for the line from the pump to the axle.

I whole heartedly disagree! While I will agree that the newer ones, especially the coil sprung ones, work awesome off road, I put that 70 CJ5 a lot of places. I did have, stock 4:88 and Powerlok, with a 2" lift. My Dad put it a lot of places stock, including early 70's Rubicon before lift kits and big tires. Mostly I had the 2" lift because the stock springs were worn out.

My buddies Rubicon('04 I think) works awesome, but he has put in a Rubicon Express long arm lift, gears, 35's, and other stuff. It is a lot cushier, and roomier. Real plasticy though.

And, I see the new Jeeps using the bypasses; they don't want to scratch up their $30,000+ rigs!

FWIW, I do not know of anyone with a new or old Jeep, that runs trails, that leaves them stock anyways. With simple mods, those old ones will go a lot of places.
