Save a ton of money by making your own bearings. It is a necessary and excellent tool. There were no problems with the bending of the petals and other things. ***REMINDER*** The driver's side spindle nut on Super Duty (and many others) has an ROUND THREAD! You're bound to bend the tabs when you tighten them, when you think about loosening them - if you're lucky. If you're unlucky, you'll mess up your axle threads and/or ruin your spindle nut and curse your birthday.
