Auto trac will burn up because it is constantly spinning (or something like that :think: ) DE will give you a better explination

I've looked under my truck and in 2wd the drive shaft doesn't turn.

How did you do that?

If your driveshaft isnt spinning, something is goofy with your t-case.

 

[Aberbaseball7]

Correct, on the auto-trac the front shaft does spin all the time. Or atleast it did on my 99 NBS so I dont see why yours inst spinning...

 

[Lowbowtie]

Yea The front Drive shaft doesn't turn unless its in 4wd of some sort. :think: I even had the wife drive the truck with me looking. When the truck is in park you can spin the drive shaft freely. :argh: Is this normal?

And it does have the AutoTrac Button. So I know I'm not too Crazy!lol

I'm gonna have to go look again. :stupidme:

What do you guys know about the ABS?

:think: In park, it spins freely? WTF? It should NOT be doing that.

 

[Whifflebat]

I thought that as they get older and more worn it becomes possible to spin it...

 

[Dark Eternal]

no it should not spin, thats one of teh reasons you cant use it. Also the case kinda freaks out when it doesnt sence the actuator there.

ABS - fuck it, rip it out, you will no longer have the sensors on the front wheels so it wont work right at all. I cant tell you how all of this goes until the weekend when I test drive mine though, so keep tuned!

Thanks Guy's :worship:

DE POst back here when you get her back on the Road? :ninja: ow:

then house come all the older chevys i see don't have the front shaft spinning when driving in 2 wheel? or is it that the auto trac case spins at all times when driving and the old the older t-cases such as np 205 203 208 don't spin all the time. and house come when i went to the dealer to get a new switch there computer listed my case as a np 208?

 

[Whifflebat]

huh?


NP246 - nbs trucks - autotrac - front shaft always spins

NP241(88-98 1/2 ton trucks), NP208, NP205 - - non autotrac, manual shift - front shaft spins only in 4x4

NP203 - old trucks - full time 4x4, i'm assuming the shaft always spins.
