Front end alignment at home

furyus2 said

Ok. I will watch some youtube videos to get an idea of what to do. I do have a digital level. My questions are how do you know the gauge is on level to start? Do you level the car front to back, and side to side to start? How do you measure 20 degrees to get the caster? Thanks.

You want whatever the car is parked on to be level, aKA your garage/ driveway. Shim under tires if not. I actually block up and level the bed of my trailer

The 20* you can go cheap and just get a protractor and mark off that angle on the floor A couple of degrees error will not affect
