I just bought a 2000 Nissan Frontier and I'd like to know the correct way to shift on the fly into and out of 4WD? I don't want to mess it up. Also is it ok to use 4WD if pavement is just wet or will that do damage?

You can shift on the fly from 2 hi to 4 hi at any time as long as you are not under power or in other words on the gas. Hold at a steady speed or let up on gas pedal a little bit then shift, DO NOT shift truck when vehicle is speeding up or taking off. Also do not shift when wheels are spinning or when you are turning a corner. The same goes for shifting from 4 hi to 2 hi. ** Now to shift into 4 lo the truck should be stopped and put trans shift into nuetral then shift transfercase into 4 lo, and never exceed 25 mph in 4 lo position !!!!!!! To shift out of 4 lo and go to 4 hi or 2 hi stop vehicle and shift trans into nuetral then make your 4x4 shift then put trans into forward or reverse gear and VROOOOOM your on your way. Remember to NEVER and i mean NEVER shift into 4 lo while vehicle is moving forward or reverse as you will do serious damage to any and all parts of drive train. You should not run 4x4 at all unless you need to pull something where you need extra traction like a boat out of water,a stuck vehicle,or if roads are slippery, or muddy. also don't be alarmed as sometimes when in 4 wheel drive and you turn corners you will notice a binding or jerking motion, this is normal and if this is occurring i would recommend going back to 2 hi position. HAPPY TRAILS to you with the new toy. I only buy vehicles with 4x4 and have never owned a 2 wheel drive in my 31 yrs of driving. I love the idea that i have extra power and traction options when i need it,the only bad thing is your boss says " what do you mean you can't make it in,you have a 4 wheel drive!

Just shift it when your stopped or going slow
and only use it when you need it on snow to
drive safely
