Rear Locker vs Center Locker in Practical 4x4 Uses??

[alumarine]

Of course a locked center diff is better than unlocked, Jesus dude do you think I am stupid?

I am saying multi-mode is the same as a normal transfer case when its locked so the only thing that adds capability is an elocker.

Whoa dude. It was the way it was written that made it easy to misinterpret.
No need to pull the think I am stupid card.

"In terms of off road ability, the unlock/lock feature on the Multi-Mode t-case (center differential) does not add anything"

In the context of the rest of the quote I posted, not so much.

Doesn't matter anyway, I was trying to drown out the people who think the center diff magically makes them more capable offroad than a normal 4runner. Mission accomplished.

If you don't think the locked T-case adds anything I know some trails that can change your mind. I'll drive my 4Runner, you can have my wife's AWD Jeep. Good luck.

I'm confused.

I understand about the center differential in the Limited that allows the wheels the freedom to move on turns on pavement.

But, in a non modified Limited, there's a way to LOCK the differentials? I've not heard that.

A rear locker was optional on 4WD SR5's and Limiteds in '96-'00. The base/SR5 4WD trucks from those years have a traditional transfer case (so, no center differential - it is always 'locked' at the transfer case if in 4WD).

Doesn't the front driveshaft always spin and it's the front differential that engages and disengages the 4WD function?

The front driveshaft *can* spin, but isn't forced to. The ADD disconnects the right front axle from the differential output. The left front axle is always connected to the left side of the diff. With the shifter in 2WD (standard j-shifter), the transfer case is mechanically disconnected from the chain drive to the front output. So, the only way the front driveshaft spins is via friction of the left side-gear on the front differential driving back through to the ring gear with no load on the right side-gear. When the truck is parked in 2WD, you can reach under the truck and just turn the front prop shaft by hand.

For 4WD to engage, the 4WD shifter needs to engage the front driveshaft AND the ADD actuator needs to connect the right axle to the right side of the diff. So, 4WD shifter engages driveshaft and the '4WD switch' on the TC, witch triggers the 4WD relay, which energizes the ADD VSV's, which move the ADD actuator, which triggers the ADD position switch that lights the light on the dash to let you know you are in 4WD.

That's all for '96-'00 j-shift trucks only. The push-button and multi-mode trucks are a bit more complicated, with extra actuators and a computer to run it all.

seems like the OP pulled the pin on a loaded question, tossed it, and ran. LOL
