Is that on both front wheels?
Can you tell if the wheel bearings that you replace were originals?
It sounds like the wheel hubs were pressed deeper onto the wheel bearings, than the wheel bearings that were removed.
Do the steering knuckles use retainer rings to limit how far in the bearings can be pressed, OR did they have a machined shoulder to limit travel? If the steering knuckles were designed for rings, and the rings were not installed before the bearings were installed, then the wheel bearings could have been installed too far in.
There's no way to fix this problem, except for adding spacers, changing wheels, OR removing and replacing the wheel bearings. You can't push the bearings ( even partially) out without damaging or destroying them.
