I'm still a bit of a vehicle neophyte, but can't you disconnect the front wheels in 4WD vehicles so the inside wheels turn separate from the outside while turning? There aren't the switches in the wheel hubs I have. Any info?

I am 100% not sure what you're asking at all, so i'm just here to tag and read some responses

There is a switch for that, it's labeled "2WD".

If I am correctly interpreting what you are saying you think both front tires are turning at the same rate when in 4wd.  Right?

They are not.  

you have a differential in between those two tires that allow them to turn at different speeds while the hubs are engaged.

This. Unless someone installed a front locker.

Rear is a different story.

Pretty much everything has a live front axle now, so I doubt there's any hubs to disengage. The front diff will allow the two front tries to spin at different speeds but the speeds between the front axle and the rear axle are different when you turn and there's where the binding is.

Manual hubs from the factory are pretty much a thing of the past unless you have a domestic 3/4 or 1 ton truck.

Gotchya. It just binds when I'm turning.

What kind of surface are you on when this happens?

You don't have a front locker, so your front wheels already spin at different speeds when turning.

Bind is normal.

The reason it binds is because it doesn't have a center differential like the 4Runners do. Those you can drive around on dry pavement in 4 high with the center diff unlocked. The Tundra and Tacoma don't have this feature so if you are on a high grip surface stick to 2WD.

Not all 4runners have the center diff. If I'm not mistaken, they were only available from '00 on up, but still an option on certain years, so don't assume it is equipped this way across the board. I know my 99 is a non center diff 4wd.

I had two Scout II that had manual front locking hubs.

The front axle actuator takes the place of the hub disconnects on that Toyota.



If the   tries to bind in 2wd, it's probably stuck engaged. They'll do that. Also bad half shafts will do that.




When in 4x4, all 4 wheels turn at the same speed. If you try to force a different speed, than at least one will slip to relieve drive line stress.

Jeep TJ and earlier all had locked hubs all the time, you just disconnected the drive to the axle but all the axle guts always turn.  Unlocking hubs can save fuel cost on a Jeep in a hurry but the install cost is high.

Yeah my 00 didn't have it but my 05 did. Wish my 15 Tacoma had it.

The 4th Gen (2005-2009) had a center diff/transfer case, which was discontinued on the 5th Gen SR5, Trail, and TRD Pro.  The Limited as an full time 4wd system, so it still has the Center diff/transfer case.

Definitely.  It's not hard to swap one into a truck without it but the actual toyota e-locker is hard to find and very sought after.

I put front and rear ARB lockers in mine, still never had a chance to use them though.
