TODAY is a Great Day to visit our Store and order the parts you need for your truck!
You need to carefully inspect the front end. Make sure tie rod sleeve bolts aren't hitting if it's lowered. Check the calipers, hoses and wheel bearings as well.

You are saying it only does it if you apply the brakes right?
