I know a shop in khadda market Islamabad, behind urdu university named Madina Auto Alignment,Guy's name Abid.
Pindi members will forget the wheel and wheels if they try him.
He has a flywheel like tool to balance rear wheels as well,giving them rotation to 80/100/120 km/hr and checking the viberations though the front wheels he drive with the help of engine,putting all the wheels on the jeck.
I drove more than 7000 km with his work flawlessly.
