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

Good part. Appears to work well.

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

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:

Great fit and shipped fast.



by:

Labeled 1 3/8” but it was actually 1.5”. Had to lathe it down myself.



by:

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.



by:

Very good, bearings fit well. I wish the stub end was fully machined.



by:

Its incredibly frustrating that etrailer will not provide dimensional information as to how far the brake plate needs to be from the tip of the axle or the bearing flange. Without this information it is very difficult to use these parts - we had to do it by trial and error and wasted a lot of time and money. The part is fine - lack of information is inexcusable.



by:

Smooth buying experience! Awesome service, tracking and delivered much faster than I thought to Canada. Looks like someone knows how to manage a business.



by:

just what I needed

great item and
great service



by:

As described and great price. Took a little longer than I expected to get it but once it actually go to USPS it was fairly quick.

Good quality and competitive price.

See what our Experts say about this TruRyde Trailer Spindles

  • What Size Axle Does a #84 Spindle Fit
    A true 1 inch spindle is a BT8 spindle, like # TRU94FR. The next closest one would be the BTR spindle which is commonly referred to as a 1-1/16 inch spindle, like # TRU44FR and is more common than the BT8. Both of these are typically used with 2,000 lb axles. A #84 spindle, like # TRU24FR or # TRU47FR is bigger and is used for 3,500 lb axles. Common sizes for these are 2-3/8 inch round axle, 3 inch round axle, and 2 inch square axle. I have linked a helpful page that shows the different...

  • How to Determine Hub Face to Hub Face Dimension for Picking out Replacement Trailer Axle
    If you are looking to order a new axle for your 5 foot wide trailer you will need to determine what the hub face to hub face dimension you would need to clear your trailer that is 5 feet (60 inches) wide. You will also need to know the width of your wheels/tires. You will take the figure and divide by half as trailer wheels have a zero offset which means exactly 50 percent of the tire width will be on either side of the hub face. You will want to have a couple inches of clearance between...

  • Can I Change a 5 on 4-1/2 Drum With A 5 on 5 Drum For A Trailer With 3,500 lb Axles
    As long as the drums have the same weight capacity as the axles that you are putting them on then there should be no problems there. If you don't already have the 5 on 5 drums that you are asking about, I recommend using the E-Z Lube Hub and Drum Assembly # 84556UC3-EZ. It has the E-Z lube cap on the end of the drum so if you have E-Z-lube axles it makes greasing your axles easier. It also works great with axles that do not have the E-Z lube option. Since you are taking the 5 on 4-1/2...

  • 4-80-8 Tire/Wheel Combo Needed as Well as 1 Spindle for Log Splitter
    The Kenda 4.80/4.00-8 Bias Trailer Tire with 8" White Wheel # AM30000 is an excellent tire and wheel combo that has a 4 on 4" bolt pattern and has review great reviews from our customers. If you just wanted the wheel it is part # AM20001 and if you just wanted the tire it is part # AM10002. We also have the Redline Spindle # TRU94FR which measures 1.25" where it installed on the axle but it measures 0.999" where the bearings ride and uses 1" bearings, # L44643.

  • 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...

  • 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.

  • Hub with Bearings that Fits BT8 2k Axle Trailer Spindle TRU94FR
    The BT8 spindle part # TRU94FR that you referenced is designed for 2,000 lb axles so for a hub that would fit this you would want the # 8-259-5UC1-EZ which comes with the correct bearings installed and is pre-greased and ready to install. The weld on portion of the spindle is 3-1/4 inches long.

  • Which 5 Bolt Hub Assembly is Recommended for Use with the Redline Spindle # TRU94FR
    On the TruRyde Spindle, part # TRU94FR, the hub assembly you would need is an idler hub assembly. An idler hub assembly does not have an integrated brake drum. It will also depend on what size wheel and tire you will be using. If you need an idler hub assembly with a 5 bolt pattern you can use the Dexter hub # 34822545BX. This is a idler hub assembly with a 5 on 4-1/2 inch bolt pattern that will work on 2000lb axles. It will only work with 8 inch to 10 inch wheels. If you need an idler...

  • Recommended Spindle/Hub Combo for a 1,750 lb Axle
    Hey Stevan, the Replacement Hub Assembly # DM04369 is just the hub, so the spindle is not included. This is a replacement part for the Demco Kar Kaddy so it'd use the existing spindle and mounting bolts to install. For a spindle, the closest it looks like we carry is a 2,000 lb spindle like the BT8 Spindle for 2,000-lb Trailer Axles # TRU94FR. This spindle would work great with the hub # 34822545BX for a 5 on 4 1/2 bolt pattern, or # AKIHUB-440-2-G-1K for a 4 on 4 bolt pattern - Both...

  • Solution for Replacement Parts for Boat Trailer With Hub Rubbing Trailer Axle
    It looks like the hub is rubbing up against the trailer axle on your boat trailer. If I had to guess, I would say since that spindle is attached to the axle with U-bolts it probably shifted over time to a point where the hub is too close to the axle. Moving the spindle out slightly so the hub is no longer contacting that axle will likely take care of the issue unless other parts are damaged. Once you remove the wheel and hub I would inspect the hub, spindle, and axle to see what damage...

  • Replacement Trailer Spindle for L44643 Inner and Outer Bearings
    A spindle that uses both inner and outer bearing L44643 makes it a BT8 spindle, # TRU94FR. Please note that welding on new spindles is a precision job and should performed by a qualified welder with experience welding on spindles. The alternative is to replace the axle. Axles are measured from hub face to hub face and from spring seat center to spring seat center. For example, the picture I have included is for axle # T20BTR-EZ-7258.

  • Is a Damaged Spindle Safe to Use If Hub Fits It
    It might seem that the spindle being slightly bent isn't a big deal but it can definitely lead to another blowout so you'll want to replace that spindle with a new one. It looks like you have a straight spindle like the standard BT8 found as part # TRU94FR for a circular end or part # TRU97FR for a square end. A damaged spindle will cause more friction which, in turn, increases the amount of heat produced which can lead to your bearings failing or a tire blowout. So any time a spindle...

    To recommend the correct replacement spindle, I'll need some more information. I'll need the axle capacity, as well as the reference numbers from the inner and outer bearing and the grease seal. If you cannot get the reference numbers, I'll need you to measure the diameter of the spindle where the inner and outer bearings ride, as well as the diameter of the spindle where the grease seal rides and the hub bore diameter where the grease seal installs. These measurements need to be precise,...
