This is the front wheel bearing kit that does both sides on a 2wd Vanagon from 84-92. It includes bearings, seals, and nuts for both sides. If you are replacing the front brake rotors it would be smart to replace these bearings at the same time. The 84 is a split year. You should check the inner diameter of the outer bearing to be sure before you place your order. The early version has a 19mm diameter and this kit is 21mm. You should be able to use an open end wrench to use as a measuring device.
