    Im new to this whole tacoma world and i have never owned a truck equipped with a locker on the front or on the rear. Now i have read my manual and it says that the locker is only supposed to be used at speeds under 5 mph. My question is if that is just Toyota being cautious or if it really will cause problems running it at a higher speed.

    it doesnt have any problem running alot higher than that my friend has done so many donuts with it on in his tacoma, with the wheels spinning like at70 mph...and mudding, so im pretty sure its alright, the locker has broke or anything and he has about 70k on his truck
    im sure itll mess up over time though especially with abuse as he has done with it locked

    He must have a 2wd. 4x4 locker is definitely for use under 5 mph... I don't know much about the 2wd however..

    you would have far less control of the rear end of your vehicle at high speed. the whole point of a differential in the first place is so you can make turns. when both your wheels are turning at the same speed all the time when one needs to go a further distance than the other a locked diff wont allow it. thats why i only use mine when im stuck.

    maybe that is obvious to you but that seemed to be your main question in your OP.

    You'll be fine, just remember the tires are locked together, thus you can only turn on a loose surface or a slippery one, turning on pavement will cause the tires to chirp and hop and possibly break something. Speed won't make a difference.

    where do you get this info from?


    you can exceed over 5mph while locked provided the conditions allow you to safely do so..but you must be under 5mph to engage/disengage the locker. other wise damage to the internals will happen.

    this topic went from a normal question to a potential train wreck in less then 6 replys :rolleyes:

    My '06 PreRunner had the locker. Make sure you're stopped when you engage it. Other than that, I've had it up to 70mph blasting down a soft sandy wash with the diff locked.

    will the locker engage if your going over 5mph, say 45mph or even high way speeds? Or would the computer override it due to the speed and not allow it to lock?

    And no I'm not willing to try it, just curious.

    Im just wondering because there is a lovely little warning sticker on the driver door that says that the locker is not to be used at speeds over 5 mph. It says to use it to get unstuck and then disengage it. ive heard of other manufactures not putting a limit on the speed. I was aware of the on the road driving characteristics due to having had some race cars that had the old "lincoln locker" rearend. it just seems odd that they would want to limit it to being used under 5mph

    That's exactly what I was thinking would happen too. Think I'll take your advice and move the button as well. Thanks!

    Can you even go that fast with the 4wd/rear lockers engaged? You're in 4lo and I'm sure your RPM will rev up REAL high. I've never had it engaged on straight-a-ways before as I only use it when needed out in the trails..

    ok, well among all that jaber your question should be answered now. it's fine to use it in swampy/sandy conditions at higher speeds. now that we know you're not just some teenager who doesn't know how a vehicle works we can probably help you more. but yeah, it's fine, just use your head and don't engage it moving or when you're turning on pavement and such.

    Spell check or not, can't argue with those videos. Snow one looks like a blast.

    Oh Jesus these threads...every goddam time.

    - Locker can be used above 5mph, but should NOT be engaged going over 5mph. Ideally, it should be engaged with NO load on the drivetrain at all, other than possibly a backwards idle to line up the locking collar splines with those of the differential carrier. Less load = less chance of breakage, less chance of losing control of the truck.

    - From factory, the truck is wired to only allow locker usage in 4wd, low range. The max speed you can hit in low range is about 35mph.

    - Locker Anytime modification allows locker usage in 4wd high and, theoretically, accidental engagement if you were to hit the button by oops.

    There's plenty of info out there on the webs about what differentials are, what lockers are, how they both work, and why...
