Build went great. Built custom axle. Drilled 4 bung holes, cleaned up the spindles, used dial indicator to make it true and mig welded it up. Welded new perches on axle tube, painted it, mounted and Done. Gone Fishing.

Great fit and shipped fast.

I purchased these hubs, spindles, wheels and tires for a machine that I'm building. Initially, I tried to source them locally, but nobody had all six items that I needed. So I turned to etrailer again, and was very well pleased. All the items are of very high quality and work together without any modification. And the price, including the (free) shipping from etrailer was less than any local vendor, and they were delivered in less than a week. etrailer comes through once again! Thank you, etrailer!



by:

Really fast shipping and product as described.
Will
use them again.



by:

Good part. Appears to work well.



by:

Should do the job. One of the two had some surface rust on it in the bearing area. Nothing real bad just needs some scotchbrite

  • Depth Measurement For Hubs That Fit A 1" Straight Spindle
    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 spindle and all 4 would be identical as far as depth. A lot of these older boat trailers use hubs that are trailer specific, and it may prove very difficult to find. We do carry replacement spindles like part # TRU59FR, if you want to change it out for a more...

  • Trailer Idler Hub Assembly For a 1" Diameter Spindle That is 4-1/4" Long
    It sounds like you are needing the Trailer Idler Hub Assembly # AKIHUB-440-2-G-1K for your trailer. This hub fits the BT8 Spindle # TRU59FR which is 1" in diameter and has a length of 4-1/4" long from the inner bearing landing to the end of the threads. The Idler Hub Assembly # AKIHUB-440-2-G-2K you found fits a BTR Spindle # TRU44FR which has a diameter of 1.063" for the hub bearings.

  • Will the Trailer Idler Hub Assembly for 2,000 lb Axles Work With a 1" Spindle
    Tom, the Trailer Idler Hub Assembly for 2,000-lb Axles # AKIHUB-440-2-G-1K are going to work with BT8 spindles like # TRU59FR which have a diameter of 1 3/8" and an overall length of 8 1/4" so it's not going to work with your current spindles. Your best bet would be to replace the entire axle with one that has more common sized spindles because I'd highly doubt you're going to find anything that works with those spindles. If you let me know the capacity of your axles, the spring seat...

  • Are the TruRyde Spindle # TRU59FR and etrailer Idler Hub Assembly # AKIHUB-545-2-2K Compatible
    The TruRyde Spindle # TRU94FR and our Trailer Idler Hub Assembly # AKIHUB-545-2-2K are not compatible, but you could use the TruRyde EZ Lube Spindle # TRU44FR instead as it has the correct spindle measurements. For a hub that will work with the TruRyde Spindle # TRU94FR you can use part # AKIHUB-545-2-1K. To determine if a hub is compatible with a specific spindle you will need to make sure that the inner diameters of the Inner Bearing, Outer Bearing, and Grease Seal of the hub matches...

  • Replacing Hubs On a 4' X 6' Carry On Trailer From 4 on 4" Lugs to 5 on 4-1/2" Lug Pattern 15" Wheels
    Your current axle on your 4' X 6' Carry on Trailer will likely have either a BT8 Spindle # TRU59FR or BTR Spindle # TRU44FR. You can determine the spindle by removing your current hub and inspecting the bearings or by measuring the spindle itself. I have included a image that shows the locations of the bearing numbers and grease seals on your current hub as well as the measurement points for spindle as well. The BT8 Spindle # TRU59FR uses Bearings # L44643 which have an inner diameter...

  • Spindle Compatible With Trailer Idler Hub Assembly AKIHUB-440-2-1K
    The Trailer Idler Hub Assembly for 2,000-lb Axles - 4 on 4 - L44643 Bearings - Pre-Greased # AKIHUB-440-2-1K won't fit your trailer spindle as it will be too long. The reason is, this hub is designed to work on BT8 spindles, which are longer than what you have. The only solution we can offer is to replace your short and older spindles with a new one that will work with the Trailer Idler Hub Assembly # AKIHUB-440-2-1K, which is the BT8 Spindle for 2,000 lb Trailer Axles # TRU59FR.

  • What Does a Damaged Trailer Spindle Look Like
    Yes, that spindle does look too beat up to be usable. I attached a link to this page that has all of the spindles we carry. You would need to pick out the one that matches the axle capacity on your trailer. It looks like maybe a 2,200 or 2,000 lb axle possibly like the # TRU59FR.

  • Should a Spindle That is Chipping be Replaced
    Anytime that a spindle is starting to take damage you will want to replace it as that will affect the performance of your bearings and seal. In this case since that chipping is right where the seal sits (as you mentioned) that will eat at the rubber seal which will likely cause it to fail. A failed seal will leak grease and cause further damage to your spindle/hub area. From the picture you sent in it looks like you have a round BT8 spindle. For replacements we have parts # TRU94FR, #...

  • What Replacement Spindle Do I Need for a Dexter 69-46 Spindle?
    As far as removing your current spindle, you will need to grind/drill off the old one. One the old spindle is removed, I recommend the BT8 Spindle for 2,000-lb Trailer Axles # TRU59FR (for a 1-3/8 diameter) or the # TRU94FR (for 1-1/4 diameter). The measurement of the diameter is the stub (innermost tube on the spindle). In order to get the correct size, I recommend measuring the stub of your old spindle once it is removed. I went ahead and attached videos of both of these spindles in order...

  • Axle Recommendation for a Converted Off-Road Trailer
    If you are planning on purchasing a new trailer axle it will have a spindle already attached to it. Installing spindles is a very precise job that should only be done by a qualified fabricator with trailer fab experience. Since your planning on using the trailer for off-road purposes a better option might be the Timbren Axle-Less systems like the # ASR2KHDS03. This will give the trailer a 4 inch lift, is setup for wide off-road tires, will give better ground clearance than a standard axle,...

  • How to Determine The Correct Replacement Trailer Hubs by Bearing Numbers or Spindle Size
    The best way to determine which replacement hubs you need for your trailer would be to remove one of the hubs and retrieve the bearings. Find the numbers stamped into the bearings and with those we will be able to get you the correct hubs. If you are unable to retrieve the bearing numbers, you can take measurements of the spindle. I have included a link to our spindle main page. At the top of the page is a diagram showing all of the measurements we would need to find the correct hubs...

  • Replacement Hub For A 1949 Or 1950 TeeNee Boat Trailer With Short Spindles
    I have a solution for you, but as the short spindles have not been produced for some time now, there will not be a hub that will fit them properly, unfortunately. You will need to replace the spindles with the BT8 Spindle for 2,000-lb Trailer Axles # TRU59FR. If you are or know a good welder, this can be done pretty easily, but you need to make sure the cross tube connecting the two spindles has an inner diameter of 1-3/8" (typically a 1-3/4" outer diameter). Once these are on, the CE...

  • Determining if 2,000 lb Axle Needs 1-1/4 inch or 1-3/8 inch BT8 Spindle
    With trailer axle components there isn't typically a way to know what you need before getting into the hub/spindle area. Basically you'll need to remove your old one first and determine if you need the 1-1/4 inch BT8 part # TRU94FR or the 1-3/8 inch # TRU59FR.

  • Which Trailer Hub and Bearings Fit Spindle # TRU59FR
    For spindle # TRU59FR, you can use hub # AKIHUB-440-2-1K. This hub comes with the proper bearings # L44643 inner and outer. The Cap has an outer diameter of 1.986 outer diameter and Seal # 34823. The hub assembly is a 4 on 4 bolt pattern for 2,000 pound axles. You will want to make sure that the old bearings are stamped with L44643. If they have different numbers, let me know what they are and I can determine what the correct replacement hub is.
