Will this fit my trailer axle?

It fits axles with a #42 spindle rated 5,200 to 7,000 lb. Confirm your spindle number and that your wheels use an 8 on 6.5 pattern with 9/16 studs.

Do I need to pack the bearings?

No. The bearing comes pre-greased with blue grease. Check the grease is clean and seated before install, and add grease per your axle maker's spec.

The hub takes a seal with a 2.250-inch inner diameter. Buy a new seal with each install; reusing an old one risks leaks and bearing damage.

What comes in the box?

The pre-greased hub-drum assembly, the blue-greased bearing and assorted metal fasteners. It does not include a seal, nut or cotter pin unless listed separately.

Is it worth it over buying hub and drum separately?

For a straight replacement, yes: the matched assembly and pre-greased bearing save time and the risk of mismatched parts. Building from loose parts only pays off if you want a specific bearing brand.

When is the price lowest?

Trailer hub prices move with steel and bearing costs and tend to dip in off-season winter months. Compare the current listing against its recent range before buying.

Our take on the Trailer Parts Pro HD42866BX-916 Pre-Greased Hub-Drum Assembly

This is a complete pre-greased hub and drum assembly for trailer axles rated 5,200 to 7,000 lb, built around a #42 spindle. It uses an 8 on 6.5 bolt pattern with 9/16-inch studs and a 2.250-inch inner seal, and ships with the bearing packed in blue grease and fasteners included. It suits a direct replacement of a worn hub-drum rather than a build from loose parts, since the bearing and hardware come in the box.
