Sharp turns while in 4WD? Truck rocks!

I was trying to get out of an icy parking lot today and was going nowhere in 2WD. So, I switched to 4WD and when I was making a turn, the truck felt like it was driving off a small step or something. Very noticeable! It was a sharp turn, but not turned all the way. Is this normal or is there something wrong? Thanks! Matt

Re: Sharp turns while in 4WD? Truck rocks!

Its normal, If you were turning sharp Left then the right front Tire would Side slip making it feel like it fell, Same way if you were turning right the Left tire would side slip. I plow Snow and I feel what you describe all the time.

Re: Sharp turns while in 4WD? Truck rocks!

Can it damage something from doing that a lot? Matt

Re: Sharp turns while in 4WD? Truck rocks!


its the result of a LOCKING Diff...the front wheels
are locked together and can not turn at uneven
speeds (as they do when the front diff is open
or unlocked)

Re: Sharp turns while in 4WD? Truck rocks!

What is happening is you have all the wheels locked up through the 4X4 and they all want to rotate at different rates. E.G different turning circles.On a loose surface the tyres can slip a little but on hard grippy surface the tyre winds up and distorts until it lets the grip go.Short wheelbase vehicles have less of a problem than our long wheelbase.
It does load up the drive components and should be considered when ever 4X4 is engaged.

[/ QUOTE ].Thanks Knapp. I have experienced this too. I try to engage my 4X4 once a month to keep everything working, on dirt roads or on paved only if it's raining as the water will act as a lubricant for the tires.

I thought I'd read in previous postings that there is no OEM locking front differential in the Super Duty trucks. Am I wrong?

[/ QUOTE ] Not locking differentials, it is a 4x4 thing,, no matter what brand. Like they mentioned above. Each front tire is traveling a different distance in a turn. So one "Binds" some and when it releases grip it will "Jump" for no better term to use.
COMPLETELY normal. DO NOT engage 4x4 on DRY PAVEMENT,, only dirt, wet or ice/snow. Other wise it CAN damage things if done often and harshly!

Only time I would use it on hard pavement like surface, is if you need traction and are driving in a straight direction. I wouldn't use it on Ice driving at any speed other then when your stuck.

You are correct. Probably wouldn't want it on everyday use truck. one front tire grabbing on dry road and the other one on ice will cause the truck to turn hard.
