2010 Sierra Jumpy Turning in 4x4

[BigZed]

Hey Guys,

 

Did a quick search but couldn't find anything on this.

 

When I'm in 4 high and I either turn to the extreme left or right while going very slow, the equivalent speed you would use to park in a parking spot, the truck lunges or kind of jumps as I make the turn.

 

I cant remember this happening last year or at least in the past 6 months.

 

Does anyone have any opinions on this behavior?

 

Truck has 130,500 km (81,000 miles) on it. SLE All-terrain.

 

Thanks

Normal if you're on dry pavement and not in auto with at least one positrak differential.

Thanks appreciate the information!

You should not have it in 4HI unless you are in snow or mud or some other off-road driving.

 

If you drive on clear pavement in 4HI, all 4x4 trucks will perform as you stated.

Good to hear, a nice relief!
