I’ve searched and searched I just can’t find anything on this for the 97-03 models. Any help??

 

The truck is locked in rwd when in 2wd.

If you are talking about a locker, detroit lockers are automatic, there is a spool that is direct, and selectable, like an ARB air locker.

All of the above are quite aggressive.

There might be a limited slip differential, or an open diff, which are a little more suitable for street use.

You can use any of those in 2wd or 4wd. The locker is specific to that differential, whether it be front or rear.

What are you trying to do or accomplish?

 

I’m trying to take the stock e locker and be able to turn it on or off in 2wd instead of just 4wd

 

There were no stock e-lockers in 97-03. What is the AXLE code on the door jamb sticker?

 

H9 it’s a 1998 F150 it’s the 50th anniversary edition lariat. I could just be confused with the way they set up the axles this is the newest truck I’ve owned and the first F150 ive owned.

 

You should have a 3.55 traction lock rear. It works with clutches and automatically locks up when you step on the throttle hard enough while letting the outside wheel turn faster than the inside wheel on turns at light throttle.

 

You have a limited slip rear differential. It is automatic, and works in 2wd or in 4wd.

 

Okay that makes since I was curious bc on pavement in 4wd the inside tire would chirp but in 2wd it wouldn’t so I didn’t know if it was something a previous owner had done or if it was 100% stock.

 

You should not drive in 4wd on pavement to begin with, and if you turn the wheels when you are, that's very hard on the drivetrain. Be glad only a wheel is chirping.

 

On dry pavement, generally no. It also depends on what you're doing. Pulling a vehicle out of a ditch? Go ahead. Using common sense is a big part of this one.

 

Nope, 4wd on pavement ONLY if you are going straight.

 

Or you want to learn how to replace a CV

 

LOL! This must be why all those full time 4WD vehicles are always broken? Oh wait, they're not. How can that be? 4WD low on pavement isn't good all the time because of the amount of torque on the diff and axles. In high, as I said, use common sense. And then there is AWD. Yes, I know it's different but there is a point where torque can be evenly distributed just as in a 4WD. Remember, this is the 21st century, not 1970.

People have a tendency to be stupid and disregard common sense which is why it's not recommended. Not because of actual effects when common sense is used. Kids are generally stupid which is why there dad's tell them not to drive in 4WD on pavement.

But by all means, do what you feel is best doing and trust it.

EDIT: Look up why a Raptor and some others come with Torsen (Torque Sensing) front differentials. Also why the Escort RS Cosworth and Sierra came with Ferguson front differentials. All current FIA Rally Cars are full time 4WD cars---not AWD drive which also biases front to back and doesn't use a center differential.

 

AWD is different than 4wd.
The control is done by sensors to modulate the front and or rear hubs or drive line on and off as needed so full control of the vehicle is accomplished.

 

Read my post again and you will see you repeated what I wrote. What I said is full time 4WD is NOT AWD.

BTW, AWD is . . . . . never mind.
