Whining sound in front wheel at speed

I'm getting a whining sound coming from the front passenger side wheel when I get to 10+ mph. At slow speed in almost sounds like an unbalanced whine (you can tell its not the full rotation, skipping sound). Obviously the faster I go the louder and more continueous it sounds. What do you guys think? Thanks.

I would suspect wheel bearing too. Get on some open road where you can turn the steering wheel a bit while you're rolling. The bearing noise should change as you put and take away different load on it.

wheel bearing or CV. I would vote wheel bearing 1st. Could be front diff, but I highly doubt it. Front diff usually starts whining at higher speeds and deffinately does not sound like an unbalanced tire.

Nice thing is the hub bearing is very easy to change on our cars.

Jack up the wheel and look for play. Also inspect the CV joint, see if the boot is torn etc. Then report back to us.

Ok thanks for the responses. Whats a CV joint? and where is it? Whats it look like? The dealer by me (McDonaugh Jeep, East Brunswick, NJ) has the wheel bearing hub assembly for $290.00 each. I need the whole assembly because the bearings are sealed right? I think I saw aftermarket and better quality for much cheaper, not sure if it was my model that I saw though. Can anyone recommend a place & brand to buy from? Thanks again for the responses.

The CV joint is part of the Front drive shaft. And it is basically a ball and socket. I'm not real sure about your wheel bearing becaus yours is pretty new. One on my 96 was like $50. Most folks here know more than me. Somebody can probably give you a better answer.

Don't know anything about the CV. I called around and found wheel bearing hub assembly for $104 each ($125 for "premium") at NAPA auto parts store by me, in stock. Not the $290 each the stealership wanted. My 2004 Grand Cherokee does have 91,000 miles on it.
