After putting the lift on my truck it developed a strange mild grinding noise that goes away when 4WD is engaged. Sounds like it's coming from the t-case or front driveshaft. This wasn't happening before the lift though, so I'm confused. The shaft isn't at an excessive angle. Any ideas?

 

what kind of lift do you have how high is it?

 

It's a Kore 3" level kit.
