Today, were going to review part number 3984. This is the Axle Tek Inner Wheel Bearing. This replacement bearing is a high quality, tapered roller wheel bearings designed for high-speed use. All bearings have industry standard number regardless of the brand. On this wheel, bearing you can actually see the part number. Itll be stamped right on there, 3984.Basically, this wheel bearing will consist of three parts.
Has the inner cone, has the tapered roller bearings and the roller bearings are actually in a cage or a roller retainer, its called. When this is installed on the spindle, it would be lubricated with either grease, wheel bearing grease or oil.One of the most critical measurements when replacing your wheel bearings is you do have to make sure the inner diameter, which is this part right in here. Needs to match what you have on the trailer right now. To get an actual measurement you would need to use either a dial or a digital caliper like we have here because most of the time the numbers are extended out to thousandths of an inch. In this case, when we measure the inner bearing, it would measure 2.625.
That would be your critical measurement.This bearing here is made to use on a bearing race, which is not included. It is sold separately. The bearing race would be part number 3920. The critical measurement on the bearing race would be the outer diameter measurement, which would be 4.438. That should do it for review on part number 3984.
