wheel bearings

I have to continually replace front wheel bearing on my 1999 Pontiac grand am. Any suggestion out there? I've tried faq and skf bearings.Can't get a week out of them. Sensor light comes on and cracking noise.

Have you been torqueing them per specs. BTW, should be done with wheels on the ground.

My mechanic assures me of the correct torque on bearing housing and wheel nut

well is your mechanic using an impact tool on these? If he is, he's frucking them up. FYI, And both sides should be done at the same time.
