    Hey guys I've got a 98 ext cab 2.7L 5-speed taco. I'm wondering about installing some type of a lunchbox locker. I will be mostly onroad with weekend excursions into the woods. I live in the northwest and go to school in Pullman. Lots of wet/snowy slick on and offroad conditions. Good idea? Bad idea? Suggestions for locker? Lemme know. Thanks guys.

    I put a lock-rite in the front diff of my '97. It works great and is quiet. I have manual locking front hubs, so it doesn't affect pavement driving at all.

    I personally wouldnt go for an auto locker. I am sure most are fine, but I just think it better to spend the extra few hundred for a manual electric locking or an ARB air locker.

    I'm on the poor college kid budget lol... My front end has auto locking hubs so idk if that would matter, it really shouldn't being as an auto locker is only engaged under power i.e. 4WD correct? Also being in the snow\slick conditions would it be more beneficial in the front..?

    Incorrect. A lunchbox locker is working ALL THE TIME. You don't engage it or disengage it. It's always locked.

    The only way to get around that, is having MANUAL locking hubs where you can disconnect the front wheels from the axle shafts (on the front that is). No way of disconnecting it on the rear wheels.
    The lunchbox lockers replace your spider gears in the rear differential.

    The lunchbox lockers have crazy characteristics as they pop/bang during regular street driving. They have to unload the torque load.

    Do some more research about them & their on-road characteristics and where to put them (front or rear) and why.

    The best all - around lunchbox locker that I've heard from many offroad enthusiasts, is the AUSSIE locker. http://www.aussielocker.com/

    You dont want one in the front . As janster said they are engaged all the time. I know from exp. On wet slick surfaces you hafta un-lock one hub for it to drive worth a damn. Being from fla i have no idea about icy, snowy surfaces but i can't imagine it being very pleasant to drive. If you can live with load/unload noises they are fine for the rear

    What I ment by engaged under power is when an auto locker is installed in the front, for the front to have "power" 4WD needs to be engaged. Auto lockers are "engaged" under power and "ratchet" when they aren't, i.e. when installed in the rear the locker is engaged while your foot is on the gas, and it ratchets in a turn with no acceleration. The ratchet\engage action is what causes the clunk\bang\pop, etc. I understand what they are and how they work. I just need advice as to what one to get and which diff to install it in..?

    Definitely install in the rear unless you have manual locking hubs, then definitely install in the front.

    Being in 4WD has nothing to do with it.

    If you have manual locking hubs - then, you're OK.

    With Auto hubs - the axleshafts & wheels are always turning and will turn the ring gear (with open diff) inside the differential. With an auto locker in there, everything can turn including the front driveshaft.
    I don't have experience with this myself, but enough research I've done in the past - I'd go with an ARB (selectable) style locker in the front.

    Janster I understand that everything is engaged and turning up front but... there wouldn't be power to the front without being in 4WD ya know what I'm sayin'..?

    When making turns, the two front wheels aren't gonna be turning at the same rates. The inside wheels will cover less distance than the outter wheel. Since the axle shafts are turning on both sides (with ADD vehicle), there will be a torque variation that the lunchbox locker will need to deal with. I don't have experience, but the locker will surely pop/bang and perhaps limit your turning radious due to that torque load.

    Do some GOOGLE research. These lockers have weird street characteristics and even worse snow characteristics.

    Obviously people have installed them. Some people hate it while others get used to its characteristics. Research research research

    The only good thing, if you don't like it.....you can remove it and put your stock spider gears back in without any other headaches to deal with. But ultimately....for the front...your best, most reliable, SAFE option is going with a selectable up front (like an ARB).

    Removing that front diff is a PITA. You should definitely take Jan's suggestion and research the crap out of the subject before you go sticking a locker in your front diff.

    Yeah I know that the IFS shit is a PITA... I had already pretty much figured on just the rear anyways...
