Engaging 4 wheel drive?
When I bought the truck about a year or so ago, I noticed that the instructions to engage 4 wheel are partially rubbed out.
From what I gather it says...
To engage HI, shift while driving
To engage Lo, Stop, put truck in neutral, shift to 4 low fast and hard. Then put truck to drive.
Does this sound right? I find sometimes it makes a grinding noise. From what i have heard, that is normal. Also seems to pop out of 4wheel with a bang.
(also says do not drive on hard surfaces, its hard on it... must drive on dirt, snow etc.
Whats going on here? And does anyone have a good picture of there instructions on there visor?

I dont think you are supposed to shift it fast and hard into 4lo. I always pull with a constant pressure and if it wont go in let the truck roll a little or move it a little then try again! Maybe thats just the way I do it, but who knows. lol. It will tell you in the owners manual of the truck if you still have that!

Here is a copy and paste from the Owners Manual.
NV-231 Transfer Case
The NV-231 transfer case offers 4 mode positions. Use the appropriate mode for the conditions described below:
2H
Rear wheel drive high range - Normal street and highway driving.
4H
Four-wheel drive high range - When driving conditions require more traction than two-wheel drive provides.
N
Neutral - Disengages both driving axles. To be used for towing only. See towing instructions for more information.
4L
Four-wheel drive low range - When maximum pulling power is require. Do not exceed 25mph (40kph).
Shifting Procedure
2H to 4H or 4H to 2H
Shifts between 2H and 4H can be done with the vehicle stopped or in motion. With vehicle in motion, the transfer case will engage/disengage faster if you momentarily release the accelerator pedal after making the shift.
4H to 4L or 4L to 4H

4H to 4L or 4L to 4H
Shifting can be performed with the vehicle rolling 2-3 mph (3-5 km/h) or completely stopped. Slow the vehicle to under 3mph, shift automatic transmission to NEUTRAL (N) or depress clutch on manual transmission. Shift transfer case lever without hesitation to the desired mode. Pausing in transfer case NEUTRAL (N) may require shutting the engine off to avoid gear clash while completing the shift. Do not attempt to shift to or from 4L with the transmission in gear.

I'd personally never engage it while moving even though my manual says I can. Just doesnt sit right with me and seems hard on the truck and why not stop since you gotta slow to around 2 mph anyway. I always stop, put the truck in nuetral, and pull the shifter to whatever I'm putting it into, put the truck in reverse and let it roll a lil, then back to drive and go. Thats just how I was taught and I always have better results like that. No grinding, popping out, or gear clash.
