Front outer Wheel Bearing. These bearings work with 80-84 Vanagons with build dates up to 11/83. The last six digits of the VIN is 023 828 or lower. They also work on 64-79 Bus. The center hole is 3/4" inside diameter. If you have a question about which bearing you need measure the inside diameter of the center hole of the bearing. This one is 3/4" as I have said but the later model one is almost an inch (15/16") in diameter so if you measure it with a ruler you should be sure which one you need before order. This is only a question if your van is an 84. Before that year use this one for sure, and after that year use the newer version for sure. Link for newer version is below.
