Q: whining noise in front end

The pulling on braking and the suspected problem with the bearing (i.e., the possible bearing noise) may be a coincidence, especially if you only repaired the brakes on one side of the vehicle. If pads and/or rotors on only one side are replaced, the braking effect (or power) will then be different from side to side and that alone can account for pulling. If you did replace the brakes (pads and rotors) on both sides, then the pulling on braking could be due to a failed bearing but it could also be due to side to side variance in tire inflation pressure, misalignment or worn suspension parts. The noise you are describing does commonly accompany bearing failure but, as you are seeing, bearing failure is not always accompanied by measurable play in the assembly. Failing bearings will make lots of noise way before there is any measurable indication (on a dial indicator) of a failure. To get the bearing inspected, and replaced if failed, please request hub assembly inspection/replacement and the responding certified mechanic will get this taken care of for you promptly.
