Roar Noise From Front End 4x4 Auto Hubs?
I Use My 2002 F350 4x4 Psd For Hauling Boats And Boat Trailers. I Usually Gross Right Around 20,000 Lbs Sometimes 22,000. When I Am Loaded With A 32 Ft Haul Trailer With 6 Trailers Stacked On It And 2 Trailers On Top Of My Cab On A Special Made Rack, I Get A Roaring Noise Out Of What Seems To Be The Front End. The Noise Comes And Goes, Maybe Every 20 Seconds Or So. I Know For Sure It Is Not Tires As I Replaced The Tires With New And It Made No Diff. I Dont Know Why, But I Feel Like Maybe My Front Hubs Are Tryiny To Engage My Front Halfshafts, Or Maybe My Transfer Case Is Trying To Spin The Front Driveshaft?? The Truck Has The Auto Locking Front Hubs. I Keep Wanting To Think That The Carrier Bearing Is Going Bad, But I Drive About 2400 Miles A Week On Average And It Gives Me Lots Of Time To Try To Determine Where The Noise Is Coming From And It Sure Seems To Be Coming From The Front. Also, When It Is Making The Roaring Noise, I Can Feel Some Light Vibration And I Feel It Most In My Feet (the Floorboard). What Kinds Of Things Can I Do To Help Diagnose What Is Going On? When I Am Empty With Just The Empty Haul Trailer You Dont Notice It As Much, And When I Have No Haul Trailer You Can Barely Feel-hear It But It Is Still There. It Is Getting Worse Though With Each Load, I Just Took A Load This Week From Illinois To Long Island New York And I Was Starting To Worry About Breaking Down. Have Any Of You Ever Heard Of Such A Thing? Can The 4x4 Auto Hubs Try To Start Engaging The Front Axles When Loaded Heavy Even If You Are Not In 4x4? Or Could This Be Something Completely Different? Thanks In Advance For Your Help!
