burn 4-wheel drive out?

[chico4554]

alright so i finally got my 5.13s installed in the rear to match the front and it got me thinking, what does it mean when someone says, "dont use 4x4 on a dry road because it will burn the 4x4 out?"

I never really knew what this meant, because it doesnt make any sense to me. I thought this because I would like to use 4x4 on the road to break in both the gears, otherwise ill never get the front broken in. The only thing i can think of is because on dirt or snow there is some slippage going on, but otherwise why would the 4x4 burn out?

Its as you said. In dirt, snow, gravel, loose road; theres slippage allowed between the front and rear. On dry pavement, slippage is very minimal. Its okay in a straight line. But in turns, it binds the drivetrain. Twisting u-joints, driveshafts, and tranny. Evently, something will fail. The reason for the binding is do to every tire having its own turn radius, which creates unequal torque. In a straight line, every tire is equal (unless a tire is smaller/bigger than the rest or dount is installed)

If want to break-in the rings. Just find a good loose gravel road to use the 4x4.

The front and rear wheels need to be able to turn at different speeds, such as when you make a turn. If you're in 4wd, the front and rear wheels are locked together and are being forced to turn at the same speed. On slippery surfaces, this isn't a problem because the wheels can sort of peel out to make up for the different speeds, but on high-traction surfaces, it will just bind up and possibly break parts.

LearJet beat me to it...

It doesn't burn out.. It just breaks..

I have seen a transfer case split in half because someone tried to do a 4 wheel burn on pavement.

now I have no Idea about this but what if you run in 4wd. but just don't lock in the front hubs or is this bad juju.

Sorry for the double post like boggin. But dude your back when did you get the clearance to play again.

That is perfectly fine. I use 2L all the time, 4WD with hubs unlocked. Makes backing trailers a lot easier on the clutch.

WARNING: Make sure your stopped before putting truck into 4WD with hubs UNLOCKED!

Not to mention pulling vehicles home when they break down on the road.

The only gripe I have with using 2L is when backing up a hill with a trailer. The clutch barely has to grab and it jerks the shit out of the whole truck.

The shuddering feels like the things gonna fall to pieces...

Yea when Ike blew through Southern Indiana, a guy's transmission in a '85 Ranger locked up in the middle of the highway going through town. I used 2L to pull him out of the road; 2H wouldn't budge him.

alright i get it. Thanks guys!

just shove a np203 in there for full-time 4-wheel drive

NO NO NO NO NO NO! That would be horrible as most if not all people who had the NP203 got ride of them and installed the NP205.
