Question:

One possibility is that one or both of your front automatic hubs (if you have 4WD) are stuck in the engaged position, causing the front drivetrain to be rotating.  Just one thing to check.  - Have someone drive the truck slowly while you lay next to it on the ground and watch to see if the front drive shaft is rotating.  Just don’t get run over, please.  - Or wrap a piece of duct tape around the front drive shaft so that it flaps against the frame.  Then listen while your driving.  Don’t forget to take it off after the test… – Jason ‘96 Explorer Limited ‘94 Explorer XLT (yeah, I have two…)

I have a 1992 Explorer Sport 5 speed with 150k miles. It just developed a strange roaring noise in the front end. It starts at about 35mph. It is more noticable while coasting or in in neutral. The wheel bearings all look ok. The tranny has sufficient oil. Any thoughts would be apprecited.  Martin
