Shipping was fast and Ahead of schedule the ordering was quick and easy.
When I opened the box I found one slotted nut was missing and the washer that goes along with it was in the bottom of the box. Overall, I am well satisfied.

Worked perfect for repairing an axle I had!



by:

I’ve had this spindle for a year and I have put nearly 30k miles on my car hauler. It has performed amazing. They come in great packaging, very sturdy and heavy duty. I’m very happy with my purchase and will happily buy more when the time comes!!!



by:

I was too cheap to replace the entire axle assembly when my bearings failed and ruined the spindle. Welding in this new spindle saved me some cash and the trailer is as good as new. Ordered a new hub assembly along with this spindle and everything went together perfectly.



by:

Extremely satisfied! Excellent customer service, delivery was right on time. The parts ordered were exactly as advertised and fit perfectly. Ordered two more hubs to overhaul my trailer axles. Highly recommend using this company for any trailer repairs.

  • Spindle for Trailer to Use with Hub that has 5 on 4-3/4 inch Bolt Pattern
    To install a hub with a 5 on 4-3/4 inch bolt pattern like the part # AKIHUB-5475-35-K that you referenced you'd have to go to a different spindle on your trailer axle as there isn't a sleeve adapter of any kind for this type of situation. For a spindle you'd want the part # TRU24FR. You'd need to find someone with experience installing spindles as it's a precision job.

  • Replacement 5 On 5 Idler Hub For Homemade Trailer
    I have a couple options for your consideration as we do not have a replacement hub or bolt on spindle that will fit your combination. First you can remove your spindle brackets and have new #84 Spindles # TRU24FR welded in place of the current spindles. This would move you to the most common spindle size and allow you to use the Trailer Idler Hub Assembly # AKIHUB-550-35-K. This will come preloaded with the new bearings, races and grease seal installed and greased. The second option...

  • What Axle Capacity Matches Spindle Diameter of 1.37 inch Where Inner Bearing Rides
    The inner bearing dimension on a spindle of 1.37 inch would indicate that the spindle is an 84 spindle like the # TRU24FR which would indicate that it's a 3,500 lb axle.

  • What Spindle Will Work for Trailer Hub Assembly with L68149 Inner and L44649 Outer Bearings
    The Trailer Hub Assembly # 84550BX that you referenced will use # L68149 as the inner bearing and # L44649 as the outer bearing. These are the inner and outer bearings used by a # 84 spindle. We offer the following spindles: #84 Spindle for 3,500-lb Trailer Axles - 1-3/4" Diameter (11-1/4" OAL) # TRU84FR [R2061-284] #84 E-Z Lube Spindle w/ Brake Flange for 3,500-lb Trailer Axle - 1-3/4" Diameter (9" OAL) # TRU74FR [R20384EZ] #84 Spindle for 3,500-lb Trailer Axles - 1-3/4" Diameter (8-1/4"...

  • What Are the Dimensions of the TruRyde #84 Spindle for 3,500-lb Trailer Axles

This spindle will fit the following bearings and components, which are all sold separately: Bearings- Inner bearing: # L68149 (1.378" inner diameter) Outer bearing: # L44649 (1.063" inner diameter) Races- Inner race: # L68111 Outer race: # L44610 Grease seal: # 58846 Inner diameter: 1.719" Outer diameter: 2.565"

  • Correct 5 Bolt Hub for #84 Spindle for 3,500-lb Trailer Axles
    Yes, I can confirm the Trailer Idler Hub Assembly part # AKIHUB-545-35-K will work with the #84 Spindle for 3,500-lb Trailer Axles part # TRU24FR.

  • Availability of Brake Mounting Flange for Axle Spindle TRU24FR
    We do, but we also have this spindle with the flange already welded on with the part # TRU74FR. Since the spindle part # TRU24FR normally fits a 2-3/8 inch diameter axle the correct flange would be the part # 4-35.

  • What Grease Seal Do I Need For A #84 Spindle
    Yes, the correct grease seal for a #84 spindle like # TRU24FR, is the Grease Seal # 58846. The inner diameter of 1.719", and an outer diameter of 2,565".

  • What Trailer Axle Spindle Has Bearings L68149 and L44649
    If you know the trailer axle capacity that's a pretty good way to determine what spindle you have. Or if you get me the bearing numbers. You can also measure the spindle where the bearings ride and with that info I can let you know what you have.

  • Availability of Spindle that Would Fit Square Tube Axle
    New spindles should be welded on only by a professional welder who has experience and the correct jigs for installing spindles perfectly straight and concentric. If not installed correctly the trailer may not track properly and uneven tire wear can occur. It might be more trouble than it's worth to try and fit a round spindle like the part # TRU24FR in a square tube axle by trimming it. We have a square version of this spindle as part # TRU47FR.

  • Recommended #84 Spindle for a Hot Walker
    The etrailer Trailer Hub and Drum Assembly for 3,500-lb E-Z Lube Axles part # AKHD-545-35-EZ-K is designed to work with an #84 spindle that has an inner bearing L68149 (1.378" inner diameter) and an outer bearing L44649 (1.063" inner diameter). Therefore, for a spindle that will work with this hub assembly, I recommend using part # TRU24FR for round or part # TRU47FR for square.

  • Replacement Hub For Boat Trailer Using Bearings L68149 And L44649
    The closest we have is Trailer Idler Hub Assembly for 3,500-lb E-Z Lube Axles - 5 on 4-1/2 - Galvanized # AKIHUB-545-35-G-EZ-K.

  • Replacement Options for Hub and Drum With 09067 Outer Bearing and 15123 Inner Bearing
    Unfortunately we do not have any hubs that use those bearing numbers. Your options would be to remove your old spindle and install a new spindle such as # TRU24FR with compatible hub and drum such as # 84546UC3. You could also replace your entire axle with one such as # 35545E-ST-89, which is rated for 3,500 lbs and has electric brakes. In order to determine the correct axle you would need to measure from hub face to hub face and spring center to spring center like in the accompanying photo....

  • Is Brown Discoloration on 3,500 lb Trailer Spindle OK
    Definitely smart to check, and you're right that the brownish discoloration on your 3,500 lb trailer spindle like # TRU24FR is perfectly normal. Just the discoloration won't be an issue, and you can leave it be as that is just caused by heat and grease. The only issue would be if it was grooved or nicked somehow, but since it's perfectly smooth like you said, then the spindle is fine.

  • How to Measure to Confirm Bearing and Spindle Compatibility
    The parts you referenced, tapered roller bearing # L68149 and idler hub assembly # 84545BX, do work together; the that bearing is the inner bearing for this hub. The bearing's inner diameter is 1.378-inches and it fits a #84 spindle like # TRU24FR. To confirm a fit on your spindle you will need to measure the spindle diameter to three decimal places, to the nearest thousandth of an inch, using a digital caliper like # PTW80157.

  • What Hubs Will Fit Redline 2-Inch x 4-Inch Round Spindle # TRU24FR
    The #84 spindle you reference, TruRyde # TRU24FR, is rated for use on 3500-lb axles. This spindle is compatible with both of the hubs you mentioned, parts # 84545BX, which is an idler hub; and # 84546UC3-EZ, which is a 10-inch drum brake hub intended for use with EZ-Lube spindles. The TruRyde spindle # TRU24FR is not an EZ-Lube spindle but it would still work with hub # 84546UC3-EZ. If you prefer a non-EZ-Lube version of this hub you can use part # 84546UC3.

  • Availability Of 5 On 5-1/2 Hubs For A 5.2K Or 6K Axle
    A #84 spindle is the standard 3,500 lb axle spindle. It uses an inner bearing L68149 (1.378" inner diameter), and an outer bearing L44649 (1.063" inner diameter). These days this is basically universal for 3,500 lb axles. What you have with your 25580 outer and LM67048 Inner bearings is either a 5,200 lb or 6,000 lb axle. The 6 on 5-1/2" bolt pattern and the 3" round tube also indicate a 5.2K or 6K axle. With your axle and bearing combination, there are not any hubs with a 5 on 5-1/2"...

We have no hubs whatsoever available for this combo let alone ones as specific as you are requesting.

The correct bearing for the 1-3/8" spindle is the L44643 bearing like that in the Bearing Kit for 1" BT8 Spindle part # BK1-100 which is designed for 2,000 lb. axles.
