I don't know much about your car. You could have multiple problems in my opinion. I can only give some ideas....Is your brake caliper sticking and heating up the rotor? Major alignment issue? Did you pack the bearing with high temperature grease? Did you over tighten the bearing creating to much drag? If it has a Race that the bearing rides against is it worn out? May be some one else with more experience can give you some better ideas good luck.

I agree that it could need a front end alignment. Does that tire wear unevenly? If so that's most likely the problem. Has the car been involved in an accident in the past? Either case may be making the left front wheel run "cocked" or slightly sideways. This would put undue stress on the hub bearing assembly. HTH. -Jim

The tires wear evenly. There is no wear on the tires they still look like new. The car was never in accident. The Brakes and calipers are good no problem there.

Check the lower engine and transmission mounts. Sometimes they wear and cause the engine/transmission assembly to sag. This will also put undue stress on the hub assembly as well as the drive axle. HTH. -Jim


Okay Thank you I will check that!


You're welcome. Glad to help. - Jim

It is very important to use a Torque wrench when tightening the axle nut and to torque to manufactures specifications. Improper torque will prematurely wear out the wheel bearing.
