Replacement Idler Hub that Takes L44649 Inner and Outer Bearings and Has a 4 on 4 Bolt Pattern

Question

Question:

Hello, I have an old dilly boat trailer that needs a new wheel hub. The bearings are 1.063inch inside diameter L44649 and I wanted to confirm that this hub will work with a spindle the this 1inch in diameter. Can you let me know?

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 for you.

Answer 1

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…

Answer 2

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…

Answer 3

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.

I am not sure what you mean by "short hub" but I went out to the warehouse and found that the Trailer Idler Hub Assembly #AKIHUB-440-2-2K you referenced has a total depth of 4-1/4" as you can see in the attached picture.

Answer 5

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…

Answer 6

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…

Answer 7

There are hubs available with a 4 on 4" bolt pattern but the measurements you gave are not what is needed to find them. Instead, you need to know the weight rating of your axle, and also what bearings your current hub has. You will need to take…

In order to determine the torque rating for the lug nuts on your trailer you will need to know check out the chart I attached that shows all of the torque specs for all the trailer lugs available based on stud size, wheel material and wheel size.

Answer 9

The difference between an load range C and load range D tire in the same size is the capacity and psi rating. The two tires will still have the same dimensions and fit on the same wheel. The D rated tire has a higher capacity. For a ST175/80D13 like…

Answer 10

Load range B trailer tires are going to have a lower capacity than C load range tires. Basically that, psi rating, and the ply rating are the only differences. A higher load range tire would last a little longer than lower load ranges of the same…

Answer 11

A BT8 spindle would have a diameter of .99 of an inch where the bearings would both install and would have a diameter of 1.24 where the great seal would ride. That would require a hub part #AKIHUB-440-2-1K for an idler hub. A BTR spindle would have…

Answer 12

To determine the size of the hub assembly you need to purchase you have to determine which bearings are in the old assembly. If the old assembly has L44649 inner bearings, you would use the hub you chose #8-258-5UC1. If the inner bearings are marked…
