Humming noise on the front passenger side of a 1997 Ford Explorer XLT may be due to a bad tire. Try to jack up the tire and spin it by hand to see if the noise is there.
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
I believe it to be the airbag (passenger) making that humming sound
It will most likely be the wheel bearing
1999 Mercury front and humming noises can because by several things. Tire noises are the most common cause. A tire that is not wearing properly can cause a humming noise.
Check your power steering pump A: check the front Left wheel bearing
radiator fan.
Worn passenger side front wheel bearings.
yes
Answer Humming noise from front endI just got my car fixed with the same problem and it was the wheel bearing and it is gone. Was it a fwd car?
It is the front hub/bearing assembly; this is a fairly common problem. Buy a new one from the dealer; some aftermarket ones are worse.
Could be many things but a front wheel bearing/hub assembly going bad comes to mind. Scalloped worn tires can give you a humming noise also.
Some ideas coulb be something is lose and is just rattling or a mechanivcal problem under the hood.
