I've done this many... many times.
1) Rotate tires to confirm first
2) Check hub bolts (while you are rotating tires)... these *love* to come loose. If loose, use some blue loctite on them.
3) If you need new hubs... check out Schram Auto Parts. They are in Michigan, and have LOTS of Kappa parts from GM scrap vehicles. Excellent service, will ship, and prices are hard to beat.
For rear hubs (I know you said your issue is up front) there is no need to pull an axle or touch the control arms. Pull the wheel, brake setup, the three hub bolts from the backside, and use a puller / slide hammer after your remove the axle nut. Only time I've pulled the control arms was to change the bearing material out for racing.
