Good part. Appears to work well.

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:

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

  • 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...

  • 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...

  • Replacement Bearing Kit For Idler Hub 5 On 4.5 With 1 Spindle and 1.24 Inner Diameter Grease Seal
    The measurements that you gave tell me that you have a BT8 Spindle # TRU59FR. If you wish to replace your bearings, races and grease seal you will want the Bearing Kit # BK1-100. This includes 2 Bearings # L44643, 2 Races # L44610, a Grease Seal # 34823 and a Cotter Pin # 165649. To make things easier you can replace your entire hub. Depending on your wheel size you can choose either the Idler Hub # AKIHUB-545-2-1K that has the 5 on 4-1/2" lug pattern you said you have with 10"-12"...

  • 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...

  • Dimensions Of Dexter Hub Assembly For 8 to 12 Inch Wheels
    The Dexter Hub Assembly, part # 34822545BX is designed to be used with 2,000 lb axles and for 8 inch to 12 inch wheels. This assembly includes bearings, races, seal, grease cap, wheel bolts and lug nuts. I have attached a photo of the hub and have the hub length noted on the photo. The length of the hub is 4-1/4 inches and the inner diameter of the inner and outer bearings, part # L44643, that are included with the hub measure 1 inch.

  • 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 Wheel Bearing Fits a Timken 07204 Race With a 1 Inch Axle
    From what I could find, the Timken 07204 Race has an outer diameter of 2.047 inches. The race that come with # DL21792 would have an outer diameter of 1.980 inches. This would be the closest option we have available. I can suggest a few replacement hubs that fit the 1 inch axle, however. If your wheels have a 5 on 4 1/2 bolt pattern, you would need either # AKHD-545-2-1K or # AKIHUB-545-2-1K. If you have a 4 on 4 bolt pattern, you would need # AKIHUB-440-2-EZ-1K. You can verify the bolt...

    Yes, they are indeed compatible. The # TRU59FR spindle is compatible with the L44643 inner and outer bearing and the 34823 grease seal. The # AKIHUB-440-2-G-1K hub kit includes the L44643 inner and outer bearing, the 34823 grease seal, the inner and outer race, grease cap and lug nuts. The hub as a 4 on 4 bolt pattern.

  • How to Determine the Correct Replacement Spindle With Bearing 07100
    Bearing 07100 are older bearings with the same dimensions as bearing # L44643. The spindles that uses those inner and outer bearings are # TRU94FR and # TRU59FR. The difference between these is one measurement, the furthest outer diameter, which is 1.25" on TRU94FR and 1.38" on TRU59FR.

  • 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...

  • 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.

  • How to Find a Replacement Spindle and Hub for a 5x10 SnowBear Utility Trailer with 2000 lb Axle
    We do have spindles and hubs for 2,000 lb axles, but we first want to determine which spindle and hub will work best for you. To do this we will need additional information about your current spindles and hubs to ensure the new spindle and hub match what you currently have.

The best way to ensure you get the correct spindle and hub is by using the part numbers of your bearings and grease seal....

    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.

  • 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,...

  • 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.
