Im having the same problem right now with a knocking, creaking noise coming from the front of my truck. I just put a adjustable 5100s on the front and leveled it 2". When I installed them, I also got an alignment and it hasn't even been 5000 miles. Any ideas on what it could be coming from? I've jacked the truck up and shook everything I can get my hands on...still nothing. You would think when they did the alignment, that they would of checked the tire rod ends and ball joints.
