He doesn't explain enough and moves on to quickly for me to fully understand what hes talking about so I'm left in the dark on a lot of the steps.No it is important, if there is shaking in your wheels you will have bad prints...think of the nut as a sideways egg or mazda rotary engine, if you turn closer to one side its towards the ends so its further away but you turn the other way its closer like the sides...it wont be full rotations just 1/4-1/2 turns left or right
