    my truck sees some street time...and when i travel to go wheeling, I drive it..no trailer for me. Considering this, and the fact that I try to pinch pennies when I can...is there anything wrong with running a D60 open? When I am 1-ton, I'll have a ff14b and detroit out back.

    when wheeling, is an open D60 more or less likely to break than a locked one?

    if running open is terrible...what kinda options should I look at? I dont want a detroit locker up front (gotta steer, dang it!)...and I dont wanna pay for an ARB. any relatively cheap and reliable alternatives?

    any thoughts would b appreciated,

    J

    Jason, nothing wrong with an open front...........you will just have 3 wheel drive instead of 4 [​IMG]. I've got a Detroit up front............ran it in sand............only time it is a steering problem is when its' under power - back off it turns. Heck, you've got that nice NP205 now, twin stick it............that way you can drop to 2WD when you're in need of a tight turning radius at TSF. That's what I'm researching right now............that and a doubler.

    hey blazzin,

    twin stick wouldnt be a bad idear I guess. I dunno, I haven't looked into it at all, does it require some kind of wacky (ie $pendy!) modification to the case? you have a detroit up front right now? it doesnt affect steering on-road when u wanna turn tight? If you're in 2wd..does it make a difference at all? man, i can't think right now...can anyone tell that its monday?! 8P

    AFA being 3wd...its all good...2 of those would be from a detroit'ed ff14b. =p

    i dunno...seems like every post on this site that is about some kind of non-detroit locker in a front D60 its always bad (ie. "dang, I broke &lt;insert locker here&gt; AGAIN arrrrrhhhgggg!"). That sucks. surely there must be an inexpensive yet reliable option here that wont cost me $500+.

    I need to get all this poop sorted out so I can wheel with some of the local CK5'ers. =)

    Well, here is the link to a write up on the twin stick - doesn't seem too technical.........<a target="_blank" href=http://darkwing.uoregon.edu/~jrice/NP205/TwinStick.html>Twin Stick Article</a>, tho I haven't gotten into the details to be honest with you.

    As far as good alternatives, a Powerlok is supposed to be the next best thing as far as traction goes.

    Yes, I have a Detroit up front right now. On road, when you are in 2WD and the hubs are unlocked, you would never know it has a Detroit. Must be Monday [​IMG]

    if my spider gears would not have been bad i would have left my rear diff open, it makes highway driving easy. and put the locker in the front, and on the road just unlock the hubs, and you never know yo have it, but when yo lock the hubs and put it in 4wd you will KNOW you have better traction. you can get a happy medium between the 2 with the rear open and the front locked, at least it works well for me, 95% highway 5% off road. I will say that after about 100 mile ont he rear locker, i have gotten kinda use to hearing that click click click when i am in a parking lot.

    It needs a bigger motor.

    Kinda depends on the type of off roading your planning. I have a detroit D70 rear and PowerLoc D60 front. For snow I wish I left the front open, in fact, my Burb will be left open. I'm not a big fan of the Detroit in the rear either, It hates turns at speed! I'm putting an Eaton in the back of my Burb ... hope that isn't quite as harsh.

    I bought it so long ago, I can't remember what it cost. In fact, when I bought it, I was told it was being discontinued (something about the four clutch unit being replaced with a 2 clutch unit .... or something like that!). I guess they decided to start making them again. It works well. Very positive locking. You gotta be careful on the slippery stuff (snow, ice), with a locker in back the truck just wants to go straight. Slow is the key when ice is present. In deep snow all 6 wheels spin (Dually), the truck slides all over, but it keeps going! They are suppose to be bullit proof. I haven't had a problem and I'm running a blown 454 (B&amp;M forced induction).

    You dont need a twin stick to get 2wd low.

    A twin stick set up allows you to operate the front wheels independantly, meaning cutting out the back drive completely.

    With any old 205, you can modify it so you can have
    4 HI
    2 HI
    N
    4 LOW
    2 LOW

    Personally I dont see all that many times, if any, that yoyu would want to run just the front wheels only. So, no twin stick for me.

    Yep, I do it all the time. You just have to make sure the front hubs are locked in first, so the gears for the front drive are spinning at the same speed as the gears for the rear drive. Then it's quite easy for the t-case to shift between 2HI and 4HI. [​IMG]

    nope that open D60 wont work at all for you.

    but I'll be a nice guy here and trade you my D44 and even custom lincoln lock it for you if you so desire!

    haha. Run it. Save your pennies for a front locker. You're already about 3 steps ahead of me. I've got a D44 and am not about to put cash into the frontend untill i can afford a proper D60

    A twin stick allows you to get Front wheel low range only so you could use the parking brake on the rears and pivot the truck using the front wheel only...

    If I'm on the trail and want 2 WD low I don't want to have to unlock my hubs...that can be unpractical.

    The big problem with the front locker comes on ice / slush / light snow. If you are ever on this, then I recommend going with the twin stick. This gives you the magic of front wheel drive, (just like the little cars!!) I have lockers front and rear, and I drive on ice and snow. Two lockers is REALLY exciting in four wheel drive on ice and light snow. This is when I disengage the rear axle and let the front axle pull me along. The corners are still some fun, but not as bad as with the rear axle trying to push you into the next county.

    BTW: The first time that you are going to miss the front locker is the time that you look out and see only 3 tires spinning!

    ice? snow? That must be when the chains for all 4 tires come out... =p

    in all seriousness, i live in a really moderte climate...sometimes we go year or two without any *real* snow or ice to speak of. In spite of that, I do have chains for all 4 tires...that'd prolly help the dual locker thing a little.
