Help with Bilstein 5100's

Sway bar or your rubbing the uca. Get the alignments first, then check for enough clearance in those spots!

 

I just noticed this today.

As I slow down, the sound slows down too, and as I speed it the sound speeds up but there's no sound when I'm going at normal city or highway speeds only when im coasting to stop or coming out of a stop. But what would it rub against? It doesnt sound like the tire is rubbing against it.... It sounds like something going at a certain speed rubbing against a metal piece, or even metal on metal.

 

Have you actually taken a look under the truck to see if anything looks out of place? Just look for something that looks like the sound you've been hearing.

Edit: Also from looking around the forums it seems you and a couple others that have the same problem all have your billies set at 2.5 Just a thought, maybe its a coincidence.
