Hello! I had to have my Axle reamed out by a Professional Heavy duty truck shop. I don't know the clearance used but I do know it needs to be right or your will ruin your axle and or your new king pin set. I purchased the "oversixed" king pin set, even though I really didn't need them. Next time I will know better.

Look in your phone book under large truck repair. I betcha you will find someone who can fit it up for you and at a fair price. It will be worth it in the long run.......
