Reply to "Rear wheel bearings"

It used to be popular to replace the sealed ball bearings with tapered roller bearings but it seems that isn't as popular as it once was. The tried and true update from OEM is to replace the smaller inner bearing with a double row bearing of the same OD. The only modification required is to shorten the spacer between the bearings by an amount equal to the extra width of the double row bearing. In fact, I believe Wilkinson sells the appropriate short spacer. The factory began using a double row inner bearing some time after their separation from Ford, so you could say this modification was "factory approved".
