Our take on the Axle Bearing Kit 10-56 Seal Trailer Axel ONE Oil Cap Dexter 12K & 15K 4.0 threads Trailer Axle Plastic Cover (BK-12000-21-36-KIT)

A complete service kit for Dexter 12,000–15,000 lb oil bath trailer axles. It bundles the inner and outer bearings with their matching races, the oil seal, oil cap, O-ring and center plug, so one box covers a full hub rebuild. It fits 8-214 and 8-216 hubs and is built for both standard-duty and heavy-duty oil bath use. Buyers comparing kits should check that their hub number and axle rating match, since generic bearing kits often lack the cap and plug this one includes.

Questions and answers

What does the kit include?
Inner and outer bearings with matching races, the oil seal, oil cap, O-ring and center plug. It is a full service set for one hub.
Which axles and hubs does it fit?
Dexter oil bath axles rated 12,000–15,000 lb with 8-214 or 8-216 hubs. Check your hub number before ordering.
Is this for oil bath or grease hubs?
Oil bath. The cap, O-ring and plug are for oil-filled hubs, not greased bearings.
Do I need one kit per wheel?
Yes. Each kit services a single hub, so order one per wheel you are rebuilding.
Can I reuse the old oil cap and seal?
The kit supplies new ones, which is the safer choice since old O-rings and seals are a common source of leaks.
