Hey Landy Get A Load Of These Connectors!

What is your vehicle again? The longest lasting drive end 6203 bearing I've ever seen was the old Delco 10DN with an external voltage regulator. They used a bearing retainer with felt seal, an open one side bearing, and special Delco Remy hectorite clay based grease. Lots of these bearings went 200,000 miles 15-years without greasing. 4-times the grease capacity.

Honorable Kragen Pep Boys AutoZone "rehashed" alternators use CHINESE bearings. Garbage. Best is Japanese NTN-LUA or made-in-Poland bearings. Be sure to install your replacement reject with Velcro and Wing Nuts.
