Grinding Noise When Turning While In 4wd

[jot-23]

There's no issues at all when in 2WD mode (or Auto) , when I manually switch into 4wd hi, it goes straight fine, only when turning it starts making this grinding noise and seems like it's stalling at low speed (don't actually dies but just feels like it needs more gas to move forward, and it's rather jerky/jumpy on tight turns) it's a 07 Silverado...

 

thanks.

Its under warranty have the dealer look at it.

Are you putting it in 4wd on dry or even wet pavement?

 

if so, thats your prob. The drive line is binding up which is making your wheels pop / jump / and make all kinds of noises... Take it in some mud, sand .... you prob wont hear any probs anymore.

Sounds like you're on dry pavement.

 

When you put the truck in 4hi or 4lo, the transfer case 'locks' the front and rear wheels together (makes it so that they have to turn at the same speed). When you turn, the front and rear wheels have to turn at different speeds. When you're in 4wd on wet pavement, snow, sand, mud, gravel etc. the wheels tires can slip, thus you don't experience any binding. When you turn in 4wd on dry pavement, it is much harder for the tires to slip, which makes it bind. (yes, I realize I started every sentence with 'when' )

+1 ! I started a post on this exact subject about 6 months ago because my truck did the same thing on dry pavement. Lucky for me the boys here had the quick and simple answer to my inquiry.

And by the way, don't feel dumb. I think everybody has done it in their first 4x4 truck. I know the first time I did it, it scared the living shit out of me.

I've tried getting back on the main road (speed limit 65) from the trails with my truck still locked in 4-LO, that was an interesting experience. I've also gotten a tire to completely lock up on a Bronco in low range with the lugs stuck on the TTB trailing arm.

thanks for quick anwsers

 

yeah, it's my first part-time 4wd. I have driven subarus all nearly all my life, so i was a bit scared when I heard that grinding today, lol.

Welcome to the GM family.

 

Please do not take this wrong but given that you were not aware of the "Do not put this vehicle in 4WD on dry pavement" (or worded something similar) warning that is not only in your manual but on the visor of your truck, I would encourage you to read the manual over before you do something that might damage the truck.

 

Plus, damage done by the owner is usually VERY hard to get warranty coverage for. The "I did not know that this would happen" excuse at the dealership will not usually fly!
