2007 WK Loud Hum and Vibration

I just got a smoking deal on a 2007 WK, its like new in all aspects with 78K miles.

I have a loud hum from the front and slight vibration can be felt in the steering wheel. Its speed dependent, does not start till I go over 20 MPH. If I make a quick steering wheel turn to the right, the sound immediatelly stops. Bring wheel back straight, hum and vibration is back. Tire pressure is 33 psi, tires are almost new.

Does this description sound like front wheel bearings ? or What ?

If wheel bearings, what is a typical dealer cost to replace. Thank You

Does the humming get louder when you steer to the left or right?

Bad wheeling. Lift all 4 tires off ground and drive it while someone listens to see which bearing is bad

I live on a back country black top road, with lots of sharp turns. Running 35-40 mpg, going around a right corner, the hum and vibration stops till I come out of the corner, then without the corner load on the front, the loud hum and vibration start immediatelly. Left corners do not seem to effect the hum/vibration.

What kind of money are Jeep dealers charging to replace both front wheel bearings. No sense in doing just the bad one with the other to follow soon.

Here in Canada a Moog bearing runs $300CAD. Easily that much for labour, making one bearing a $600 job. Ridiculous for the 5 bolts you need to remove to swap them out (2 brake caliper bolts, 3 bearing bolts). It's an easy driveway DIY job. Did mine for the first time in an hour. I went with Moog bearings. I paid local retail due to time constraints but Rock Auto has them for $150CAD. Less if you're in the States.

Truly, this is not a job that requires a trip to the stealership. If you can pull on a wrench, you can change your wheel bearings. Check out this DIY video:

Thanks to all for the help. I will check out the U Tube on bearing change. The WK has a set of quite worn down Goodyear Fortera tires. I have read on the web that when these tires wear down, they get real noisy. I, today, bought a new set of Cooper Discover A/T-3 tires. I will have them on tuesday morning, next week. This will prove without question tires or bearings. Many thanks
