I own a 2000 Nissan Frontier 4X4. I have not had occasion to use the 4 wheel drive. Can you tell me how to put the truck in 4 wheel drive and take it out? Do not have a manual. Thanks!

Assuming yours is the 2 gear stick layout this is roughly how it works.
The smaller gear shift should be to the left of the normal gearstick.
It should be in the fully forward position. This means it is in 2 wheel drive, high ratio, for normal road driving. (Rear wheels).
Pulling the stick back ONE notch engages 4 wheel drive, high ratio. Used for snowy, icy, slippery conditions as well as light off roading. (Keep the speed under 50mph).
Pushing down and back another notch engages neutral in the transfer box. This means ALL drive is DISCONNECTED even if you use the normal gearbox.
**Try to avoid this one**!!
Pulling the stick back the last notch engages 4 wheel drive, LOW ratio. This is for the more extreme off roading conditions such as VERY steep hills. Not usually used in normal day to day driving.
The two fully forward positions, (2High and 4High), will be the ones used the most.

I have a 86 gmc s -15 and I need to shift it from 2 low to 2 high - it would save gas I believe, how do I do this correctly?

Most shifts can be done on the fly by moving the selector breaking the power by lift ting the foot of the gas for a sec.. To really save on gas have locking hubs fitted to the front wheels and in the unlock position the vehicle is like a 2 wheel drive vehicle. Check the operators manual or down load it from the GHM web site.

I have a 2000 gmc and my 4-wheel drive will not lock in. the actuator and transfer case are engaging but the wheels are not locking in. What should i look forto see what the problem is?

Ihave the manuals for up to 99 but i don't think chevy changed the system ot 2000 . The unit is vacuum opperated and when the drive gear inside the transaxle is engaged the wheels will spin there is no locking hub involved in the system witch means the problem is coming from behind that system . Ineed to read somethings in the manual but the games are coming on so i will get back to you later to day with an answer And what else dose it or dosen't do reguard the 4 wheel what dose the shift indicator light indiacte and are you getting any codes there is a lot of wireing to do with the transfer case and how it interacts with the transmission

Four wheel drive stuck in neutral. Won't go into 2high or back to 4 wheel drive. Transfer case was replaced. Its a 2000 Jimmy.

If you have the push buttons on the dash board you must follow the instructions in your owners manual to return the transfer case to 2wd from neutral. I don't remember for sure but I think you must have the transmission in neutral, foot on brake, press and hold both 2wd and 4wdlow buttons at same time. My father who lives 45 miles from me has the Jimmy, I don't. Hope this helps, Jim
