Sources of Various Front Underbody Noises

Various front underbody noises may originate from several different sources and are often difficult to locate and diagnose. Common noise locations include:

^ # 1 (engine) crossmember rivets - primarily the rivet or "huck fastener" at the lower left front, behind the steering gear

^ loose or improperly seated spring shock tower rivets/bolts

^ loose or misaligned transmission crossmembers

^ loose or improperly seated front leaf spring bracket rivets

^ loose radius arm brackets

^ loose axle pivot brackets

Other underbody areas that produce similar noises include:

^ transfer case skid plate

^ leaf spring bushings

^ steering intermediate shafts

^ shock bolts

^ bumper brackets

^ brakes

Other Service Bulletins have been published to address the proper repair of these concerns.
