etrailer Trailer Hubs and Drums - Hub - AKIHUB-440-2-G-EZ-1K Review Video

Thanks for the pictures! If your spindle is 3-3/4" with the threads included then the Easy Grease Trailer Idler Hub Assembly item #AKIHUB-440-2-G-EZ-1K will not fit. This would be why you couldn't get the castle nut to thread. It sounds like…

The #AKIHUB-545-2-G-2K uses #L44649 bearings with an inner diameter of 1.063" and also has a 5 on 4-1/2 bolt pattern. Since you need #L44643 bearings with an ID of 1" and a 4 on 4 bolt pattern the correct part would be the Trailer Idler Hub…

It sounds like you have a standard 1 inch straight spindle. Because it is for a boat trailer, I recommend replacing your hubs and bearings with a galvanized hub to reduce corrosion. My recommendation is the #AKIHUB-440-2-G-EZ-1K for a 4 on 4 inch…

Yes, you can go with hub #AKIHUB-545-2-G-1K since it uses the same bearings and seal size as your regular hub #AKIHUB-440-2-G-1K. Keep in mind that you will also have to switch to wheels with the 5 on 4-1/2 bolt pattern. I would assume you are…

The trailer hub part #AKIHUB-440-2-1K matches exactly what you would need. Bearings, bolt pattern and stud dimensions are the exact same.

There are not any hubs that have that 4 on 110mm bolt pattern. All our hubs with 4 bolts are the standard trailer 4 on 4 inch pattern. I recommend the Trailer Idler Hub Assembly for 2,000-lb Axles - 4 on 4 #AKIHUB-440-2-1K which will fit 1 inch…

For a standard axle we have the Trailer Axle with Idler Hubs - 4 on 4 Bolt Pattern #e25GR which is rated for 2,000 lbs but the spring seats are 48" apart on center so for this to fit you'll have to cut off the current sets and have new ones,…

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…

The largest diameter tire we have that is compatible with a 12 inch wheel is a ST145/R12 size tire which measures 21.3 inches in diameter. For this I recommend using the Kenda Karrier S-Trail #AM10140 which has a load range of E (1,520 lbs at 80 psi)…

We do have hubs available for a 1" straight spindle in part #AKIHUB-440-2-EZ-1K. This hub measures 4-1/4" deep so it will run a bit longer than the hub you are looking for. There are a total of 4 hubs that we carry for a 1" straight…

Where are you measuring the 3-3/4 inches from? Just the portion that is 1 inch? With or without the threads? If the measurement of the spindle where it's 1 inch in diameter is 3-3/4 inches without the threads being factored in yes, the hub part…

The two bearings you mentioned have different inner diameters. The #L44643 has an inner diameter that is exactly 1 inch and the #L44649 is 1.06 inch. This may not seem like a lot but it's a big enough difference to prevent the hub you have now…
