radiator fan.
posible chance of wheel bearings worn. jack car up & rotate wheels check for excessive movement (grip wheel top & bottom try to rock)hope this helps. steve.
it would most likely be the bearings but in some cases sometimes the axle make a humming noise when traveling at high speeds.(front wheel drive)
is the humming coming from the front end of the vehicle? i have a 1996 explorer with the same issue. yes the noise come from the front but not all the time seems to make the humming noise when it gets hot
ABSOLUTELY NOT!! Use a dolly on the front wheels.
thumping sound coming from front wheels when you let go of the gas pedal going at a moderate spped?
Could be the bearings.
Check the bearings.
Perhaps the cooling fan is running?
Check the wheel bearing.
its coming from the front end from the wheels we thought it was the wheel bearing
Before I can answer that question, can you describe where the ticking noise is coming from? Front of the vehicle? Rear? Engine? Is it coming from your Wheels? If its coming from the front of the vehicle you might require an oil change. If its coming from the rear of the vehicle it could be your axle. If its coming from your wheels it could be either wheel bearings or a backing plate for your brakes. Does it happen at regular intervals? Are they random and sporadic?
Could be a wheel bearing, brake pads worn,
