Several years ago, there was a lengthy discussion about different mfg wheel bearings. I remember the thread because I was planning to replace all 4 of mine. The final concensus was that Delco was the best, not for price, but for reliability.

Now, there is a HD rear offered with a better bearing than OEM Delco. The rears are more prone to failure than the front. Here's the description. Sounds like a Timken style bearing.
Manufactured by a leading American Hub Bearing manufacturer designed to produce an advanced rear hub for the 1984 to 1996 Corvettes. The uniqueness of this hub bearing is the use of a tapered roller bearing with a nitrate hardened race. The OE design hub uses ball bearings with a machined race into the hub assembly. The redesigned assembly includes a nitrate hardened race machined into an American forged hub. The combination of a super hard surface with tapered roller bearings, produces an increase in surface area for side load which delivers improved durability and performance.
Features Include:

American Forged Hub and Spindle Flange Assemblies
Re-designed With Tapered Roller Bearings and Races
Tapered Bearings increase Load Surface for Extended Life
Manufacture to ISO 9001 and TS16949 Standards
