    If the wheels were run on a dynamic balance then I'd look at the CV 
joint.

    Well on the Toyota the brake hoses tend to be on the robust side. Not 
unusual to last 20 years with no problems. IF the caliper is hanging the 
rotor will be blued. That should stand out to ANY tire mounter. Since you 
suggest that the wheels WERE balanced and are NOT out of round in either 
axis, then not knowing all that was or wasn't checked, I'd suspect a CV 
joint.  THOSE on the Corollas tend to crap out sometime after 10 years.
Much 
better than American cars.

    Here is what strikes me. He just got 4 new tires. It is hitting only
ONE 
side of the car. (Right front). It was something that a worker hot to MAKE

sales would likely not see. Suggest that obvious BRAKE things hanging pads

and blued rotors weren't present. So it is a process of elimination. If I 
assume even marginal competence of the tire store folks - something they'd

NOT necessarily pick up on would be a suspension part or CV joint.
