am i suppose to drive with 4x4 in neutral position or in 2H, whats the difference???

 

and i on this question i mean like when i dont want to be in 4x4 and im on the highway or just crusing around

 

2 high is for everyday driving. Neutral is for towing the truck. 4 high for when traction is needed. 4 low is for MAXIMUM traction.

 

Yeah, 2hi for on the street. Neutral is just like the transmission's neutral, it will disconnect BOTH driveshafts.

4HI is for dirt, gravel, deep snow, etc. It is a locked position meaning the front and rear axles are spun at exactly the same rate. When you turn, all 4 wheels take a different path through the turn, so they all travel a different rate. The differentials can take care of the right and left wheel on each axle traveling at different rates, but since the axles are locked together, one front wheel and one back wheel MUST be able to travel the same rate. Since all 4 wheels are rotating at a different rate, and one front wheel and one back wheel need to travel the same rate, driveline bindup occurs on hard, high traction surfaces. On loose, low traction surfaces, the wheels can slip to make up for the difference when you turn.

4Lo is the same thing, but is geared down more (2.72:1 on the np231 t case). 4lo does not give you more traction... you'll get the same traction in 4hi as you do 4lo, but have a lot more torque put to the axles and another gear reduction. It is used for climbing steep hills or crawling over rocks at a very slow pace and for pulling really heavy objects very short distances (like pulling your buddy out of a ditch :P).

 

umm lol well ive been driving it around in N forever, front drive shaft is in backseat of truck, so i should put it in 2H then i guess

 

You haven't been driving it in neutral. You can't drive it in neutral. You should check the shift linkage to make sure you're in the selection you think you're in.

 

If youve been driving in neutral youve been visiting the same place for a long time.

Like he said, thats not actually possible. Neutral is usually kindof a pain to get it into vs the other actual gear locations.

 

hmmm i checked, i took those stupid skull shift ***** off from 5 years ago and put stock ones back on, its seems ive been driving around in 4H but i dont have a front driveshaft in atm so i should be ok right? i went ahead and put it in 2H

 

Ya you should be okay. The 4wd light should have been on to tell you it is in 4wd, unless the light bulb is dead. Why did you take off the driveshaft?

 

Asside from getting worse mileage it shouldnt have hurt anything unless you drove it at a high rate of speed.
