Timken rear wheel bearing installation

Most newer vehicles don't use a bearing like a "green" bearing they use a bearing that uses the axle as the inner race, which is much worse. The main reason that the "green" was labeled as a race only bearing is it was first used in drag racing applications because you can't adjust the tapered bearing pre-load with a spool. Then it was realized that it was a suitable replacement for the street also. About the only place that a "green" bearing doesn't work well and is not recommened is in road race or circle track applications because of the heavy side loading. A tapered bearing will carry more load than a ball bearing will in this case. I myself prefer tapered bearings, but will tell you I have both style bearings in my cars.

There is one thing that should put any doubters at ease, 7 1/4's came from the factory with a "green" style bearing and how many of those things are on the road? more than we can count.
