Re: Rear wheel bearings - Timken part number
The original rear wheel bearings were made with spiral grooves in the roller elements. The material is also softer than the current repos. The repos do not have the spirals and are very hard and tend to wear the axle housing hubs. The original design was an overkill and many of the original bearings have survived in serviceable condition. I see them at swap meets all the time. I recommend using only the originals.
