locker question?

do tacomas have better performance with the rear diff locker engaged? if so, how does the truck perform at high speeds with the diff locked?

You shouldn't use the locker at all unless you need to use it. Do not use it on pavement. The locker should only be used in offroad situations when traction is limited (for instance, boat ramps, on offroad trails, etc).

If you have a 4WD, then you can only use the locker in 4lo range (from the factory).

The locker is not designed to give the truck overall performance. It's only there to help you gain traction when you need it. So - if you're stuck somewhere in some mud (for example) and you engage the locker....at that moment, it's the best damn piece of performance you could have.

oh you guys are no fun. i have a perma-lock in my rear end ( not able to be dis-engauged) and is awesome.... turning is fine as long as you keep your foot slightly on the gas. never ever let off throttle in a turn locked and on pavement. but a solid locked rear en is effin awesome.

Your perma-lock is NOT the same as a TRD e-locker.

I've never heard of perma-lock and tried to research it....but couldn't find any good info.

Does it pop & bang while you're driving/turning?

the name of it is not a perma- lock... i was just stating i am permanently locked. i have the powertrax locker for the tundra rear end(8.4) and your right it isnt like the tacoma e-locker. ive taken those heap of shit lockers you have in your rear end out many many times for friends that would rather run a powertrax. and no it doesn not pop and bang when you are turning, if it does, then more than likely it was et up wrong, or its user error. like i said, a locker can be driven on on asphalt as long as through turns you remain slightly on the throttle. it isnt a spool man... its a locker. huge difference.

a permanently locked diff is a spool and driving around on pavement with your rear-end locked is terrible idea.

So it does unlock in a turn.

Quote:
The figure on the bottom of the diagram (See Detail) demonstrates the operation of the LOCK-RIGHT Locker. When powering straight ahead, the cross-shaft engages the saddles in the drivers at an angle such that, in addition to rotating the drivers, forces the teeth of the drivers into engagement with the teeth of the respective couplers. The harder the driving torque, the stronger the tooth engagement. When entering a turn, the driver on the outside of the turn advances ahead of the cross shaft so there is no torque or outward force imposed on this driver. The opposing driver remains fully engaged delivering engine power. After about 1° of rotation, the pins in the driver bottom out in the holes of the opposing driver, so it is now restrained from further rotation. Because the coupler is splined to the axle, it continues to rotate ahead of the driver. The positive angle on the coupler and driver teeth then enables the driver to disengage from the coupler with 1/2° of additional rotation. As the vehicle continues through the turn, the driver repeatedly engages and disengages from the coupler, making the aforementioned ratcheting sound. The springs between the two drivers ensure that the driver will reengage with the coupler when the vehicle exits the turn. The cross-shaft contacting the saddles provides the final engagement force, not the springs. In summary, the LOCK-RIGHT Locker offers full wheel differentiation combined with maximum traction.

First off....If you have a transer case and 4hi/4lo - you should not drive in 4WD on dry pavement. Here's why:
http://www.4x4abc.com/4WD101/def_turnpart.html

For everything they've listed in that article - using the locker only makes those situations even worse.

There are tons of different traction devices out there.
Here's another article
http://www.therangerstation.com/Maga...%2006/tech.htm

For reference, the toyota e-locker is a *selectable* fulltime locker.

that is indeed true. until you really need it and you find something has fouled out with your electrical system. happens more than you would think. hence why you never see a true prerunner/race truck/ buggy/ class one/ class 16/ class 10, etc running a e-locker.

now in a RACE would you want to lose 4 minutes trying to play with a damn locker to get it to engage of would you rather have something based off of a ratcheting system that is guaranteed to work? im almost positive we could put that crap e-locker into my rear end and it wouldnt be able to hang with the power of the truck... i think ill stick with my ratcheting type.

was it the factory setup ring and pinion? and i understand u werent talking about a race situation, however... plan and build for the worst. and mind me asking what brand the 2 ratcheting type lockers were that you saw destroyed? because so far we have thrown a detroit into a 823hp car and we sheared driveshafts before the locker even brushed the pimp juice off its boots. and the pwertrax in my truck so far takes 400 like a champ.
