Worn front end parts, and shifted steel belts in the tires. Loose wheels?

Did the shaking start before or after you replaced the hub? Did you use a torque wrench to tighten, the axle nut? And the lug nuts? I ask because you may have warped the rotor during this process, Front end parts are checked for play, any alignment or tire shop can do this if you need advice.

I BELIVE THE SHAKING STARTED AFTER THE HUB ASSEMBLY WAS REPLACED, THE HUB ASSEMBLY WAS REPLACED BECAUSE WHEN PURCHASED NEW TIRES. THE MECHANIC SHOWED ME THE PLAY OR SHAKE THE WHEELS HAD AFTER TIGHTENING THE WHEELS BACK ON AFTER REPLACING THE TIRES. AND THEN AFTER THE HUB ASSEMBLY WAS CHANGED ON BOTH SIDES THATS WHEN THE SHAKING BEGAIN TO BE ACCESIVE. AND I DONT BELIEVE A TORQUE WRENCH WAS USED. I ALSO HAD A UNCERTIFIED MECHANIC DO THE JOB, SO IM ON MY WAY 2 HAVE AN ALIGNMENT SHOP TEST DRIVE AND TELL ME WHAT THEY THINK.
ANY OTHER ADVISE?
FROM YOU BEFORE I GO WILL BE APPRECIATED.

THANKS A MILLION

If an air impact was used to put the tires back on, or to tighten the axle nut, Either the rotor was warped by excessive force applied when the lug nuts were improperly thightened, or the new hub bearing can be damaged when the axle nut is nut torqued to proper specs! Or they blew the call on what part needed to be replaced, was there any growling noise after 35 mph?
