The Low-Down on the Trailer Idler Hub Assembly for 2,000-lb Axles Video

The BTR and BT8 denotations refer to the spindle, not the trailer hub. The difference between a BTR and BT8 spindle is that the BTR spindle uses a 1.063" diameter L44649 bearing and the BT8 spindle uses a 0.99" diameter L44643 bearing. In…

Idler hub #AKIHUB-440-2-2K does indeed fit on a spindle that takes L44649 bearings as both the inner and outer. The hub includes the races (already pressed in) the bearings, a seal, grease cap, and lug nuts. I have linked a video review of this hub…

I really wish there was a way to determine what bearings a trailer needed without actually pulling the wheel off and checking, but there isn't. The only two solution I have for you would be to remove the hubs and get the numbers that are stamped…

You will need to remove your hub, remove the seal and get the bearing numbers and seal numbers from what you have right now and then you will be able to pick out the correct kit. I attached a picture that shows bearings, races, and seals where you…

Thank you for the photo of your vintage utility trailer's spindle. The simplest and surest way to identify a compatible trailer hub is to identify the inner and outer bearings and the grease seal it uses. Matching up those components along with…

You will need to remove the hubs of your 2005 Fleetwood Yuma Pop Up camper and remove the bearings in that hub in order to find out what would work as a replacement. There will be numbers stamped on the bearings. With those numbers we can determine…

I wasn't quite sure the exact measurement you were referring to in regards to "diameter of the rim alignment ledge" for the Trailer Idler Hub Assembly for 2,000-lb Axles #AKIHUB-440-2-2K so I took a number of measurements of this hub.…

The wheel pilot hole will only matter if A) the wheel centers on the hub and uses wheel bolts, nut lug nuts, to secure to the hub or B) if the hole is too small on a hub that uses lug nuts. If your wheels secure to the hub using lug nuts then the…

I have a solution for you. You would actually want the part #AKIHUB-440-2-2K as it has a 4 on 4 inch bolt pattern like you need and the bearings that come with the hub are designed to fit a hub with 1-1/16 inner diameter bearings.

The importance of matching a wheel's pilot hole diameter to the part of the hub that fits through it depends on the type of wheel. A hub-centric wheel uses the pilot hole to center the wheel on the hub and also to bear some of the total weight…

The pilot diameter on a wheel, like the one with part #AM30620, is the diameter of the bigger hole that is directly in the middle of the wheel. The pilot hole diameter of the wheel for the part I just measured is 2.84". I have attached a picture…

The pilot hole on a wheel for a trailer only matters if the wheel secures to the hub using lug bolts instead of lug nuts or if the hole size is too small to fit over the hub. One of our 13 inch tire and wheel combos with the 4 on 4 bolt pattern does…
