I put a leveling kit on my truck last year... Everything is stock besides my leveling kit and exhaust... As of lately I've noticed some "creaking" when I turn up into my drive way, or any other turn that is an incline... It sounds as if it is coming from the back, and at times it sounds as if it is coming from the front... My truck is brand new with only 11k miles on it... Any ideas on what it could be?

 

Bump no idea coming from the rear.
