Traction Control Kicking In?

[BLUEBYRD07]

I have a 2007 NBS GMC Sierra 4x4 and have the superlift 6 inch lift and I notice when I take sharp curves especially at aincline or decline traction control kicks in and makes a "Gruntting" sound in the front end? Any help is much appreciated.

They will blame it on the aftermarket liftand probably will not warranty it

And most likely rightfully so.

Sounds like you have your auto-trak switch on. It will engage the front diff. while turning sharply at low speed and cause the front end to buck and bark at ya.
