That depends on the noise. Could be pads/shoes, rotor/drum, hub bearings, etc. Have the front end properly checked out. Guessing costs lots of bucks.
== == Could be the transmission, or a front brake is sticking on.
This could be a bad strut or ball joint. If the noise is constant when you drive this is probably the cause. If the noise only happens when you hit a bigger bump/pothole I would check your motor mounts, this was the cause on my thunderbird.
A bad wheel bearing
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.
mine doing the same when turning been to garage could be broke spring or strut top bearing .
I had a noise in the front end of my 2004 Mountaineer similar to what you described and it was front wheel bearings on the passenger side. $291.
It could be the passenger side hub/bearing assembly is bad. I wouldn't drive it any further than the closest garage for repair.
Check your power steering pump A: check the front Left wheel bearing
rack and pinion
that is either your front right wheel bearing or your coil spring is turning need new suspension..$$$$
State your noise.
It could be a worn ball joint, worn out frount bearings. No mater what it is, have it inspected by a mechantic. I didn't and had a ball joint break and lost a wheel. As luck would have it I was in my driveway at the time.
