Welding up front diff's

I need some opinions on welding up the front diff on an 89 waggy. I have manual locking hubs and I mostly use it for wheelin. I figured if I was driving on grass or hard pack I could unlock one of the front hubs. How hard is it to turn on soft dirt and mud??

I have waggy 44's under my XJ front and rear with full spools in both.

In dirt/grass/even on the rocks it's not bad. You lose a fair bit of turing radius but last time I was in Tellico I made no more turning corrections than anyone else and I was the only one spooled (or welded) up front.

I think I will go ahead and do it. The most that can happen is it breaking then I would have to buy a locker anyway.

Mine would not turn at all......until I installed the hydro assist. Problem solved.

i'm going to start by welding up my rear first, then if i still have traction problems i'll weld up the front, or maybe a lunchbox locker. i can't afford a selectable locker any time soon. i'll run it until it breaks.

Since you have selectable hubs, I say go for it. There is really no reason not to. While you are on the street, you can unlock them both. When on trails, lock one or the other. If it gets nasty lock them both. It gives you many options that are a benefit over a standard locker. In fact the only benefit to having a selectable locker is that you dont ever have to get out. Personally, I have more time/energy than money.

while it seems like a good idea to wheel with 1 hub unlocked, it is actually stressing the locked in axle to the point that youll br breaking that one much more often,since it is by itself doing 100% of the work pulling,instead of 50%.

nothing wrong with a welded front if youre gonna do a ram assist to help you get the tires pointed where you want them. other wise,youll be hating life trying to manhandle the wheels left or right,or youll be spending ALOTof time jumping in and out to lock/unlock it.

my 2 cents,anyway . if youre gonna do the "1 locked hub" thing,make sure you carry twice as many spares for that side

One of our Colo pals did this in 2006 before our Moab trip. His rig had 35's. He could barely turn on the trails, blew p/s fluid all over the place due to the strain, had to jump in and out of the truck to unlock a hub dozens and dozens of times, and mangled a front u-joint. Of course the trails were all slickrock.

I have an ARB up front with 33's and it is virtually impossible to turn on slickrock.

No idea about less tractive surfaces.

All true...

Thats why I ONLY run with one locked on light trails. Most of the time, when I am on hard packed trails where I have to do a lot of turning and am at hi risk of added stress, I just run in 2wd. With the rear spooled, I havent come across many spots where I need 4wd, but not bad enough to lock in both fronts... Make sense?

If and when you do weld the front or rear diff's make sure you clean out all the little weld splatter balls that may fall inside the diff's. Though they be small, they can do a lot of damage to gears and bearings.

Good Luck

Or, you could be running 4wd with open front... and not have to hop in and out of the cab all the time or running 2wd when you could have 3wd with less exercise I think having one of the fronts pulling all the time is more helpful than both fronts pulling together, on rare occasions.

The stuff I run I can get by without front locker 99% of the time anyway. But each situation is different I am sure. If I didn't have a locker already I wouldn't spend the substantial sum of $$ nor would I do the lincoln locker or even an auto locker due to the hassles. I'm glad I got the ARB, wouldn't trade it, but couldn't afford it today.

Alright, since everyone else is giving opinions, I mine as well.

I welded my front W/T D44 with 34" tires, and the steering radius was greatly affected when the hubs were locked. Unlocked, it's just like normal. I never got out and unlocked a hub so I could turn better. I just shifted from D to R more times. It seemed a little harder to turn on dirt, but not too much for me to handle. The larger the tires you're going to run, the harder the steering will be. Also, if you're a rock crawler, it's really hard to turn on rocks. Steering radius will be your major hurt, but that just means a 3 point turn will become a 5 point turn. It gets annoying on long windy days. Other than all that, it's not too bad. It gives you a heck of a lot more traction for wheeling. The traction benefit outweighed my preferences, so I did it, and after 2 runs, I loved the difference. But then it was time to swap in my 1 ton stuff, so my experience isn't long term.

But don't be fooled...you can turn when moving with all 4 wheels locked. It's not as easy as 3, and your turning radius is much larger, but it wasn't a big deal with me.

My $.02
