03 explorer grinding noise

Alright so I'm having a problem with my 2003 Ford Explorer. I've recently noticed that when I get to above 40 mph, if my steering wheel is straight, I hear a loud kind of grinding or humming sound coming from my left driver side front. If I am going about 65 mph, it gets even louder and if I crank the steering wheel to the left, that's when it really gets noisy but as soon as I crank it to the right, the problems gone. When I do hear the hummin sound, I can feel it in the steering wheel. I have replaced al of the tires and it didn't help. Also, the car slightly pulls me to the right.

I was away all weekend so I didn't have a chance to respond, but your symptoms as described are consistent with a wheel bearing failure. Most likely, the front right wheel bearing as it's the one that receives most load under a left hand turn. So your diagnosis of a wheel bearing seems very reasonable.

Thank you for that, now I see that you have to buy the whole hub assembly instead of just a bearing, is that true?

yes, the hub/ bearing come as a unit with the ABS sensor bolted on. You have to pull the big axle nut and push the half shaft inward thru the splined hub.... the unit bolts on with 3 bolts from the backside. Sometimes they have Loctite on them and are difficult to remove.... pushing the axle shaft inward an inch will get the CV joint back away from the hub so you have a little bit more access to the bolt heads.

Mines 2wd though so I don't have a Cv, it's pretty much just take of the hub and put on the new one right?

So I did both the front wheel hubs on the explorer and the sound is still there but it's not as loud. Now I'm thinking its my tires because my passenger front tire is brand spanken new and by driver front tire is at about 40% tread. Could that cause my problem?

front tire size on a 2 x 4 should not be a problem unless you have ABS on the hubs and the brakes are involved .. You could put the new tire in the back and see if the noise changes ?

I'm seeing a lot of reviews online that say this year for exlorers is a clunker. Is that true?
