Nice upgrade of the axle on my [online] trailer. I had no confidence towing my home made teardrop camper until I installed this axle. The package was damaged in shipping and eTrailer quickly replaced the missing parts.

Ordered spindle nuts and washers at etrailer after trying all the local parts stores. Was exactly what I needed. If I had checked e trailers online site first, I could have found all the bearings and nuts needed. It would have saved me a lot of time and money. I know where to look next time I need trailer parts. They have a great selection of parts and the prices are good.

I was very pleased because I was told that there was a backorder on the hub that I ordered and was not expecting to get until December, so much to my surprise it showed up at my front door this afternoon. Thank you for the great service and Cudos to Alex for his help in making this happen. I would recommend to everyone to shop with etrailer.com for their trailer wheel parts. I was very pleased for the great service.

6 wks. ago I started on a refurbishing project off a 1988 Holsclaw boat trailer. I stripped all the paint off, ground and sanded the rust, primed and painted everything, replaced ALL the fasteners with stainless stell and some galvanized. I ordered several things from etrailer.com . Everything I ordered was to exact specifications and the shipping was on-time, everytime. I ordered several bearing items to repack the hubs, this coupler and nifty lifting handle, transom tie down brackets, spare tire carrier and 3 new 570x80 tires mounted on galvanized rims and the company installed stems, free of charge! I love the way this project came out and I've thoroughly enjoyed shopping @ etrailer.com! Thank you!

I purchased new bearings, hubs, brake rotor hubs, brake pads, grease caps with rubber inserts, wheels with tires mounted, center caps and lug nuts. All of it was shipped and received in 4 days with free shipping. I have made many large purchases from etrailer and referred them to many people. They have always been great to work with. The quality is very good and don't have one bad thing to say against them. They are my go to store for my utility trailer, enclosed trailer, camper, boat, and truck. Thanks etrailer!!

Brake Drum/Hub unit and associated parts arrived quickly and in great shape! Waiting for warmer weather to install. Have used e-trailer parts before to rebuild all brakes, hubs and bearings on camping trailer last summer but over-torqued one bearing set and had an outer bearing failure - almost lost the wheel! This unit will replace that damaged hub which was gouged by riding on the washer and spindle nut causing grease cap not to seal and leak grease. These parts are first class and fit and install perfectly!

First of all the delivery arrived in less then 4 days. Two large heavy packages with for disk brake kits and the required bearings. All was available and allowed us to install and replace the by corrosion destroyed old brakes. The only thing I did not ordered and had to hunt down locally was a washer which goes in the front of the bearing seal, just before the nut. Should had known that this is an extra part and order it at as well. Anyway all other parts fit well and allowed to rebuild the trailer brakes very quickly to be back on the road.

First off I purchased 1" castle nuts, tang type spindle washers and 2 wheel hubs for a 3500 lb tandem trailer. I wish I had pictures during the assembly but I don't, however these parts all assembled perfectly. The hubs were pre-greased, so all I did was use brake cleaner on the wheel spindles to clean up, the hubs slid on with no problem, the tang washers fit perfectly and the castle nut threaded on with ease, the hub included new lug nuts which made the whole repair a breeze! Very pleased with the purchase and ease of assembly, I was going to piece out the bearings and races but for the price of a complete hub it made more sense to buy it already greased and assembled. E trailers videos and instructions are great to consider before attempting to install the parts.

Ask the Experts about this TruRyde Accessories and Parts



  • What are the Inner and Outer Diameters of the TruRyde Trailer Spindle Nut
    I pulled the TruRyde Spindle Nut, # 165686, and took some measurements for you. This nut has an inner diameter of .93 inches and and outer diameter of 1.45 inches. This spindle nut is designed to fit all spindles that accept a 1 inch nut. I have attached a photo of the measurements I took for you and a photo of where to measure on your spindle to see if this nut will fit.

  • Why Does One Brake Assembly Drag more than the Other After Brake Install
    If you installed self-adjusting brake assemblies then you would be fine as the brake tension will adjust itself. If you installed manual adjusting brake assemblies you would need properly adjust the brakes to get the correct amount of drag on all hubs. To see how to set the proper drag on trailer brakes check out the video I attached. Fast forward to the 4:30 mark. Remove the adjusting hole cover from the adjusting slot on the bottom of the brake backing plate. With a screwdriver or standard...

  • How Tight Does the Castle Nut on a Trailer Spindle Need To Be
    According to our installers you will tighten the trailer spindle nut until it stops by itself. In other words do not torque it down as hard as you can. It just has to be tight. A little play is to be expected. You do not want to torque it down too tight, because that makes the bearings too tight and then that generates heat and your bearings come apart. You might want to try tightening it a few times to get a feel for where it seems like the spindle nut naturally stops. Once it is fairly...

  • What Size Socket Works with 1 Inch Spindle Castle Nut # 165686?
    The TruRyde Spindle Nut # 165686 has an outer measurement of 1.45 inches. You will use a 1-1/2 inch socket on this castle nut or we usually use a channel lock for these installations. I've attached a video of an installation of a hub to assist. You don't want to torque these down tight as you do want to have slight movement and the cotter pin will keep it in place.

  • Torque Rating for Spindle Castle Nut
    When installing the castle nut on the end of the spindle, there is no specific torque rating. The nut is ran down until there is no side to side play in the hub, and then backed off to the next notch in the castle nut so the tang washer or cotter pin can secure the nut. Over-tightening the castle nut can damage the bearings, races and spindle. If you click on the video link I provided, and fast forward to the 4:45 minute mark, you can see the procedure.

  • Availability of a Replacement Castle Nut for a Harbor Freight Trailer
    25 mm is very close to 1 inch, so there is a good chance the castle nut part # 165686 would fit as it is 1 inch. This has 14 threads per inch, so you will need to compare that to your spindle to determine if it will match up.

  • Availability of a Replacement Castle Nut for Trailer Spindle
    We have a few options that could work for you, but you will need to measure the threads of your spindle to determine which would work. For a 1 inch spindle nut you would need the part # 165686, for a 7/8 inch nut you would need part # 165931. These are the two most popular sizes.

  • Replacement Seals and Castle Nut for 2000-lb Dexter Axle with EZ-Lube Spindles and 5-Lug Hubs
    The best way to identify replacement grease seals (and bearings and races) is by the original part reference number. The linked photo shows the typical location and appearance of these part numbers. It can be a bit of work to get the parts clean enough to read the part numbers, but this is the preferred method. The alternative is to take precise measurements (of the seal itself or the spindle) using a digital caliper. You can then use the seal's part number or its inner and outer dimensions...

  • Availability of Castle Nut for Utility Trailer Hubs
    I believe you are referring to a castle nut like the TruRyde 1" # 165686, which is what secures the hub to a trailer spindle. As long as the spindles on your trailer use a 1" diameter castle nut, this will work perfectly as a replacement.

  • Can the Trailer Hub and Drum Assembly # 84546UC3-EZ be Installed on Either the Left or Right Side
    The Trailer Hub and Drum Assembly # 84546UC3-EZ that you referenced can work on left or right sides of a trailer. This gets held on with a castle nut like part # 165686. Check out the video I attached on removing and reinstalling trailer hubs to see how it all comes apart and goes back together.

  • Spindle Nut Recommendation for a 3,500 lb Axle
    Since you have a 3,500 lb axle most likely the diameter of the threaded portion of the spindle is 1 inch. You will need to verify that. And since the spindle has a hole in it for a cotter pin you would need a castle nut. For that I would recommend the Trailer Spindle Nut # 165686. For a compatible cotter pin I would recommend the Cotter Pin part # 165649. The Spindle Nut Kit # RG05-100 that you referenced is for a different style spindle so I would not recommend it for you.

  • Spindle Nut Kit Recommendation for a Dexter 6k Axle
    Since the D60 Dexter Axle uses a cotter pin and castle nut the # RG05-100 would not be the correct kit for you. For that I would recommend the Trailer Spindle Nut # 165686. For a compatible cotter pin I would recommend the Cotter Pin part # 165649. People use channel locks typically for installation and removal of these castle nuts since they don't really get torqued down and the length of the spindle prevents most standard sockets from being easily used.

  • 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 #...

  • Replacement Axle Nut for 3500 lb Boat Trailer Axles
    We have what you need! For EZ-Lube axles which are very common on boat trailers you want to use the Spindle Nut Kit for EZ Lube Axles part # RG05-100. This will have two nuts, washers and keepers. For the non EZ-Lube axles use the Trailer Spindle Nut 1" part # 165686 and the Cotter Pin part # 165649. these are individual so you will want two of each to have all you need. You can confirm these will fit on your axles by measuring your spindle and ensuring that your it has 1" threads on it.

  • Can Performance Tool Installation Set Be Used On Grease Seal With Diameter Of 3.37 Inches
    The discs that are included with part # PTW83020 include discs that have a diameter of 2.47 inches and 2.555 inches. The inside diameter of the 10-36 Grease Seals, part # RG06-070 is 2.25 inches so the tool with the larger disc will work for installation. You will want to make sure you have the tool centered properly so you catch the outer ring of the seal when using it to install. A socket is normally not used on a spindle nut like part # 165686. Typically channel locks are used...

    It looks like you might be asking about a few different torque specs so I'll address all of them separately. For a trailer axle spindle nut like part # 165686 you will need to run the spindle nut down until there is no more side-to-side play in the hub and then back it off to the next notch so you can secure the cotter pin, like part # 165649, through the spindle. When it comes to hanger bolts like the Redline # 166081 there isn't a specific torque rating either as you just need to make...
