ditto on what bob said.dont weld the front unless you know all the problems that will arise and are ready and willing to deal with it.i pearsonly love mine being locked but on hard serfaces
it is hell to turn but in dirt and mud it is fine,but the traction is amaizing.but a lsd in the front would probaly be a very happy medium between open and locked.

With an LSD in the front and the hubs locked, is the handling the same when you compare 4WD engaged to 4WD not engaged on a gen1?
Normally I drive in 2WD hubs locked on the trail and only engage 4WD when absolutely necessary. Will I experience the funky handling of a front LSD in 2WD or does the rotational difference between the 2 wheels get sent out the drive shaft when it is disengaged?

I haven't logged too many hours myself yet. But I would say that it is more noticeable in 2WD as the fronts aren't pulling you at all. So all you feel is the LSD binding then slipping when turning. The front tires are "reactive" and not "proactive" so to speak.

Thanks for the input, it helps. I had ARBs front and rear in my last truck (Landcruiser) but don't want to spend that much on the Monty. Never had a LSD in the front before so your feed back is appreciated. Cal <img src="/forums/images/graemlins/patriot.gif" alt="" />

Well, here are my impressions, categorized by road surface, hub position/t-case position: (this is a genI, 4d, front and rear lsd's, 33" muds with 2000kms on them)
-On icy roads in 2wd hubs/locked on the highway, it is downright dangerous, IMHO, and I will unlock the hubs next time I encounter said conditions. But on dry roads (AGAIN with hubs locked in 2wd) there is a little bit of feedback from the wheel, but no big change in handling.
-On icy roads in 2wd/hubs UNlocked there is ZERO handling effect.
-On snowy roads in 4WD/Hubs locked handling is predictable, and though slighly twitchy in turns, once you learn to modulate the throttle properly, it handles fine.
-OFFROAD... well, let's just say its a night and day difference. I've only tested it on snowy trails yet, but it was equal and sometimes better than a front locker for hill climbs. Turning radius is affected, but hey, that's why you have reverse... overall it made a huge difference to my truck's capability in the snow...
Having said all this, it appears I lucked out with a very tight unit, and I did not, nor do I intend to put friction modifier in the diff oil. If this was a daily driver I probably would, but for driving to the trail, its fine.

Thanks Phil, good information. So on snowy roads in 4WD/hubs locked going thru a turn you need to easy off the power a bit to unload the LSD so the truck will turn easier? Cal <img src="/forums/images/graemlins/patriot.gif" alt="" />

Thanks for the info Phil!
Definitely agree with not putting the friction modifier in the front diff. You want it to be very sticky when you really need it.
i'm gonna keep my eye out for a front LSD. I finally solved some other problems with my truck and I'm ready to try some new mods.

Ahh, there may be the key point, as compared to what I have encountered thus far...

PHIL The very first thing I noticed was that I accidentally had my hubs locked. In 2wd, dry pavement, it was really scary. It did not want to turn, then suddenly.... Whammo! tip into the turn. Pretty spooky the first time it happened. Dan (HMD) was behind me on our way in to Marble on the first day of the Co. trip. I think he got a good laugh, as I got a close up of the grill of a Ford Superduty. On the trail, I did not notice anything, hubs locked or unlocked. It drove no different than any other 4x4 I've ever owned. (disclaimer about the monty just plain ole' being better than any other 4x4 I've owned, but just for reference of the topic. <img src="/forums/images/graemlins/smile.gif" alt="" />) About halfway through the trip, I asked why nobody got out to unlock their hubs when we'd get back to the highway, for the the trip back to camp. I was informed that I was the only one with my hubs locked <img src="/forums/images/graemlins/pfft.gif" alt="" /> Anyhow, by that time I had gotten used to the way it drove on pavement. <img src="/forums/images/graemlins/rolleyes.gif" alt="" />
