Comments about National Ball Bearing:

Designed to original specifications of the 1966-69 Lincoln Continental, and even with an improvement: This replacement has a rubber O-ring seal that can only serve as a secondary oil seal, something the original wheel bearings did not have. The only complaint I have is that it did not have installation instructions, which I think would have clarified exactly how the bearing should slide on; I had to guess how to install it.
