approx cost to replace front wheel drive axle and hub assembly

Hi well depends on how much the bearing you buy is normally 100 for part some more some less.2 hrs labor so you could be looking at from 150 -250 estamate

Thank you. Can you give me your opinion on my sub-question/statements regarding the high pitch hum when driving that goes away when veering right? Also the Low Track light comes on and stays on steady when car is on.

Yes this is typical of a bad wheel bearing and also the abs sensor will most likely be connected to the same problem. so most likely replaceing the wheel bearing will cure both of these concerns. good luck

THANK YOU BillyMac!! This is what I needed to hear. The test now is to determine which wheel (frnt driver's side or frnt passenger side).. So if you have any ideas as to how to find this out, I'd sure apprecaite hearing back. When in the car, the driver says he hears the hum more prevalent on the driver's side and the passenger believes they here it more on the passenger side.. So it's been hard to determine which wheel has gone bad.. The humming is so bad and so loud that it's difficult to determine which side it's coming from. thank you again for your help!!

Hi most likely they are both bad it is common for noise to be from both but one is always louder replace the loudest first then if still noisy replace the other.

you can raise front wheels grab tire top and bottom side to side the one that has the most movement is the worst. however no movement is acceptable
