Video Transcript for Review of TruRyde 1 Inch Diameter Trailer Spindle Castle Nut - 165686

Hi, everybody. Andy here with And today we're just gonna take a very quick look at this trailer spindle nut. This bare metal finish castle nut is for one-inch spindles. So it has to have one inch in diameter, and the overall height, just to be very specific, is gonna be 0.532 inches tall, and this is 14 threads per inch. And that's gonna conclude our brief look today.

I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me..

Castle nut for 1" spindles. Bare metal finish.


great website, easy to order from, quick shipping! Customer Service is quick to respond to questions



Worked out great when needed during a roadside repair.
Already ordered another backup.


exact replacement, they shipped it fast,always great prices and in stock,

I just Rebuilt my trailer using etrialer for all the parts, brake lights bearings winch,they even had all the parts to rebuilt the hyd actuator


Worked perfect


Need them quick and they made it happen a day sooner than expected … Thank you


After being in storage, in a field, for more than 2 years, Water had contaminated the original hub, pitting the bearings and races and they had not been serviced since, at least 1999. I polished up the EZ lube spindles, flushed out the old grease and I was ready. Everything fit perfectly. It was aa perfect match. Used new Nuts and Washers. re-installed the Wheels and Tires, Torqued to 90-10lb. The old 6 x 4 Wells Cargo trailer is once again Ready for the coming rendezvous season.


Did not fit axle spindle so I'll be returning the 2 nuts. Had to get correct size locally so I could finish assembly.


Worked very well. On a difficulty scale of 1-10, with 10 being the hardest, this was a 3.


The products appear to be ok. I would give the products 4 out of 5 stars. The 2 star rating is because of the poor shipping.

I ordered 2 leaf springs, 2 spindle nuts and 3 spindle washers. The first box showed up quickly (3 days) but it only contained 1 leaf spring. I called etrailer and they shipped a second leaf spring. After 5 days the package was at my local UPS distribution center but the tracking info said the package had been damaged and ups was contacting the shipper. I found out from ups that the spring had come out of the box, and they did not know who to deliver the spring to. I called etrailer again to discuss the damaged package but etrailer would not ship another spring until the damaged box/loose spring mystery was solved. Another week passed. I finally got the second leaf spring today, but it took about 3 weeks from the initial order date.


Thanks for getting it shipped so quickly - well done!


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!

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.


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.


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 . 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 @! Thank you!


The part is what I ordered. But what is almost as important is the inside sales person who helped me with my order. MarthaO was so much better than average and an example for every other inside sales person to emulate. Thank you Martha!


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 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!!


Mike H. Was really helpful & knowledgable . Thx for all ur help !


Absolutely phenomenal customer service! Made my order, but realized I needed 2 seals.. sent them an email to change my order, and recieved a phone call and they fixed it for me.

FAST SHIPPING! and GREAT packing. I ordered 2 bearing/seal sets, 2 seals, 2 spindle washers, and 2 axle nuts and package came with a box with paper padding, then 3 separate padded envelopes with my orders...

Couldn't find a place with better prices... I will be an customer for life.
