First, I have never done the front bearings on a 2WD '99 Blazer. However, what you are describing sounds the same as a pickup but smaller. After removal of the rotor, look in the back of the spindle. You will see 4 bolts, they might be 19mm. removal of these bolts will permit the removal of the bearing assembly. It won't be cheap for you will have to buy the entire casting with the bearings already pressed in. Hope this helps..
