First, I will admit to doing the tapered conversion on mine, as I bought into all the hype about the original roller bearings "not holding up" under the stresses of radial tires and/or disk brakes. However, knowing what I know now, and many years of experience working with late model vehicles. I tend to agree with 3Bs statements. It might be worth it to mention that all modern cars, with only a few exceptions, use ball bearings, with most of them being a non adjustable sealed style bearing. They get 100k+ miles out of those without any means of adjustment, and with disk brakes and radial tires.
