Happy Halloween!
Because I do have some days vacation coming I like to get rid of the growling sound coming from the rear of our 2002 Explorer (V6, M/T 5-Spd, 2WD). The noise depends on vehicle speed only, no difference with load or w/o. Starts at 25mph, loudest at 55mph.
I do know there are two possible issues that may cause the growl: rear wheel bearings or differential bearings.
But I am not sure which bearings do cause the growling noise.
To rule out the tires I have changed front left to rear right and front right with rear left. No change to the growling noise.
Have changed rear axle fluid to a thicker viscosity (SAE 90 GL-5). No difference.
Let my wife drive the car while I was on the back seat. If I sit left I hear it coming from the left. If I sit right I think it is coming from the right. If I sit in the middle I hear it from behind me.
What can I do to find out whether it's time to change the wheel bearings or overhaul the differential?
Like to hear your thoughts/ideas. Thank you!
