Replace a lost or damaged nut retainer with this equivalent part.


Product appear to work well. Little question on the time it took to ship.


All parts ordered to replace a complete brake system on a 25-year-old boat trailer fit perfectly. Ashly from etrailer was very knowledgeable regarding are needs. Thank you!


I was glad etrailer had these. I didn't know where else to look but etrailer came through again as usual.


All my items were received in timely fashion. Great service @ etrailer.
However, Dexter (I ordered original Dexter parts) needs to up the game on packaging. I ordered four hub assemblies and the bearings were placed in a plastic bag which I'm sure banged around on the hub. A bubble envelope would have been nice to protect the bearings.
I'm looking forward to upgrading my trailer with new Dexter Nev-R-Adjust brakes as was getting tired of constantly manually adjusting the brakes. Glad that etrailer has all the parts I need to do the job.

After a year and a 800 mile trip, everything is working great. Feels like a new trailer.
Dixon R - 10/23/2018


They had the parts I needed. They delivered them when and where they were supposed to. And the contact person knew their stuff and kept me updated.


has performed as expected would buy aga in


fast shipping


Great service
Always have the correct


This was for a replacement part that I did not receive with the axle bearing kit. etrailer was very helpful with getting me the part.


This product not seem to fit the axle nut as snuggly I wanted. I actually went back to the old cotter pin, because it felt as though it might come off if I hit a big bump.


It's currently winter and the RV is in storage. Prior to that, when the RV was in use, I had no problems with the jam nut retainers.


Nice stock retaining nut. Fits as should and does what it should. Replaced missing one on my trailer after bearings disengrated and destroyed nut.


Excellent service and delivery. Complete follow thru from E Trailer staff keeping me informed on order status. i have used etrailer in the past for other items and always the same. Excellent!!


Fit and quality as advertised

still working perfect
David J - 03/16/2021


I couldn’t believe you had my order ready to ship within two hours after my request. Of course, they arrived earlier than expected. I wanted to have a spare set of these retainers for a long time since I like packing my bearings by hand.I am very satisfied with the quality of the product as well as the service.


Items were top quality and arrived as promised. Customer service was great in helping identify what was required. I recommend your company to all my friends and i have been doing business with you fir years and have always had great service.


Ordering parts are easy going. Great help while ordering. Parts are even better than expected. Will definitely be a repeat customer


Very professional and helpful.
use etrailer again with our question.


The retainer fit perfectly and is working with no issues.


Fit perfect!


great value. timely shipping. will order a lot more from etrailer


They worked as new, no issues.

Many a loaded trailer trips and all is still doing great! Its so nice when a product works like it should!

  • How To Secure A Hub Assembly To A Spindle On A 3,500 Lb. Axle
    The majority of most axles use either a retaining nut or cotter pin with a "D" washer and castle nut to secure the hub onto the spindle. I am not sure what you are referring to as most common axle types do not use a lock washer to secure the hub assembly to the spindle, however I have included all the parts you will need to do so. For the retaining nut you will need the Replacement Nut Retainer part # 6-190. If you need the "D" washer and castle nut you will want the "D" Washer part #...

  • Installation of Electric Brake Replacement Assemblies on Wells Cargo Dual Axle Trailer
    When installing electric brakes on your Wells Cargo tandem axle trailer, you will want either the Electric Trailer Brake Kit - Self-Adjusting - 12" # AKEBRK-7-SA or the 10" # AKEBRK-35-SA. You can simply put a tape measure on your hub to see which one you need. I've attached videos of the installations to assist. It is just as common for assemblies not to use a cotter pin and it is for them to use a cotter pin on that spindle nut. Some will use a castle nut like # 165686 with the cotter...

  • Replacement Washer for an EZ Lube Trailer Spindle
    EZ lube spindles generally use a tang washer to prevent the castle nut from turning. There are different sizes available depending on what is needed. For example, # 5-101 has an inner diameter of 1 inch. Washer # 5-71 has a different design and a 1-1/2 inch inner diameter. Washer # 5-59 is similar but larger with a 1-3/4 inch inner diameter. Sometimes you will see a D-shaped opening on an EZ spindle washer such as # 5-23. On this one the distance from the straight edge to the furthest...

  • D Washer Replacement Needed for a Spindle
    It sounds like the washer you are looking for is like part # 5-23 which I have added a photo with specs for you to reference. This type of washer is held in place with a spindle washer like part # 5-101. Are you looking for a replacement bearing as well? If you could let me know what the bearing number is, like the the popular # L44649, then I can help you out with getting a replacement.

  • How to Remove a Hub From a Trailer Spindle
    To remove a hub from an axle, you will need to first remove the grease cap on the end of the hub. This will expose the end of the spindle. Once at this point, you will need to see if you have an EZ-Lube spindle, like # TRU77FR, or a standard spindle, like # TRU57FR. If you have the standard spindle, there will be a castle nut threaded onto the end of said spindle that is locking a fairly large washer in place. This will be locked in place by a cotter pin, like # 165649. These will all...
