Help I jest got my car back from the shop an that replace my Wheel bearings Both lower control arms and ball joints an the car is still shaking at 50 mph an above what do I do it’s a 2006 ss Colbalt

 

Is that the concern you brought it in for? typically, wheel bearing, bushings and ball joints don't cause vibrations. the bearing would have to be near falling out. if they found worn parts during an inspection it would make sense to replace them.
if the vibration is a new concern...something went wrong during installation...go back to that shop. If the vibration was the original concern that they never fixed. have the tires road forced balanced to rule them out. if the problem started after driving thru mud and snow....check for mud or ice build up in the wheels...if yes...powerwash it out.

 

check your wheels/tires

 

im guessin he took it in for a rotation as well or that the shop took all 4 wheels off and put a bent one up front or lost a weight on one of em
