Well---

Since you're gonna drive it through the dealers front window, putting it in 4WD might give you a little more lift when you hit the curb going in :0)

 

i find it very easy to fish tail on wet roads when it is in RWD. Would you guys recommend putting it in 4 wheel drive when it rains?

 

No just tone it down save the nascar throttle for dry days.

 

Like he said, if you're just driving too quickly, then just tone it down and you should be fine...However, do what you need to do to feel safe...If you're uncomfortable driving in 2WD in the rain then put it in 4HI just watch it.

I used to be so scared to drive in the rain, bc I almost died in a car wreck back in Jan 2008 caused by rain, that I wouldn't drive without the truck in 4wd if it was raining out...Nothing ever went wrong from it or anything, I just didn't drive too fast.

it wasn't a convertible, they had to cut me out of the car lol

 

Holy **** thats an accident! Everything turned out ok? What did you hit?

 

My friend has a GMC Sierra Denali and it is always in 4WD and it is perfectly fine when it is on dry roads. What is the difference between his 4WD and mine?

And I am thinking about taking my truck to the drag strip. To avoid spinning my tires at the line, would you recommend putting in in 4WD, I mean I'm just going straight, no turning involved (until the end that is).

 

Correct me if i'm wrong but don't those chev/gmc's have Auto 4WD? So once engaged it kicks the front to tires in when need be, and turns them off when your not spinning.

 

Stupid cell phone

 

Yeah those GM's and fords and "all time" or "auto" 4wd run in rear wheel drive but if the rear wheels slip at all it slams it into four wheel and then kicks itself back out after traction is fully regained.. This means no burnouts. Kind of makes me wonder if that causes alot more wear and tear on the transfercase or driveline the way it engages and disengages when the rear wheels are already spinning.
I know the GM front diff bearings with the all time 4wd doesn't take long to be completely worn out we've replaced them in my buddies 06 silverado twice already.

 

When you push the auto 4wd button the front end is engaged (your front axles, diff., front drive shaft) and all is spinning. It just isn't engaged in the transfer case. Only the back wheels have power. When the vehicle detects slip (determines this by the wheel sensors), the transfer case engages and you have 50-50 front and rear

i would not use 4WD at hight speeds, i personally do not use 4WD over 80 Km/h (55MPH)

4WD is for lose surface roads only, (you risk snapping axles blowing up diff etc if you drive on dry pavement) you manual has all the information in it, you should read it all.

its "4 Wheel drive" not "4 Wheel stop" as my dad puts it so if your slipping in the ran you should probably slow down, or get better tires. it only helps traction during acceleration and not braking

i usually see alot more 4WD trucks in the ditch when it snows because they think it will drive thu everything it won't
