2013 SILVERADO FRONT WHEELS LOCK UP

[Brentonct]

I have a 2013 silverado and the front wheels lock up in 4x4 but work fine in 2wd i dont have a any codes or light on or anything, soon as i put it in 4x4 and go forward they lock up and im not sure why?!

I would start with trying to narrow down where the binding is occurring. Put the truck in 4wd, Jack it up so all the tires are off the ground and see what happens. Maybe remove the front driveshaft see if it makes a difference. 

 

Has it always done this? Tire size uniform? Are the front and rear differential ratios the same?

agreed, theres only 2 things that it could be, front differential or transfer case. put it in 4wd trans neutral ,disconnect the front drive shaft and see which end of the driveshaft you can't turn. front wheels off the ground of course. then get back to us.

"Lock up" on a hard surface as in bind or don't move ?

thinkn about it you will need all wheels off the ground to check it. transfer case failure is more likely and far easier repair than front diff

You could also test it on wet grass, snow, or slippery mud. Just to see how the front end responds.
