Had to drill new holes in both spindles for the cotter pin. I used lippert brake drums .other than that all worked well.

Now this was awesome. I did have to get turned down a little so I could press it in to axle but that's perfect so it was tight and straight. Then welded the back to secure.

5.2k-7k axles are 3"OD and 2 1/2" inside diameter on a standard #42 axle. My fault I didn't cut the old one off first. You had better check before ordering. I have no idea where this one would be used.

Wrong diameter to fit the axle tube

I am sorry to hear this is not fitting your axle tube. What diameter do you need to fit your specific axle tube?



by:

The spindle wasn't quite the 2 1/4 " therefore it slowed down the welding process. overall, I am very satisfied with the quality of it.The ship[ping was extremely fast. Much better quality than the factory one that snapped in half.Time will tell!!

SHIPPED LOOSE IN BOX PARTS MISSING BEARINGS DAMAGED. SHIPPED MY ACTUATOR IN A BOX WITH TWO SPINDLES. WHY OR WHO WOULD DO THIS. SPENT THREE THOUSAND DOLLARS ON NEW PARTSTHAT ARE MISSING PIECES DEAMAGED AND SCRATCHED UP. THIS IS NOTHING NEW WITH ETRAILER.



by:

I bought an older home built trailer that needed spindles and I was not sure which ones I needed. I called etrailer and Brittany was able to figure out what I needed with the limited amount of information that I was able to provide. These spindle were the correct ones and fit without any issues. The spindles are solid and very well built.



by:

the product is great which is why purchased it to rebuild my axles on my gooseneck car hauler. I was greatly disappointed in the shipping which turned out to be more of a poorly planned joke. First product was back ordered and I was never informed of the 1 month lead time it took. I only got emails pushing the shipping date back one week at a time. I finally reached out and was Informed they were waiting for the manufacture to build the product. When I finally got the 4 spindles the box was absolutely destroyed. Spindles were loosely put in box allowing 40 lbs of metal to roll freely which tore the box to pieces. Now I have spindles that are missing 3 out of 4 castle nuts and washers. Two of the four spindles have dents and small imperfections from them bouncing around on each other. Packaging needs to be seriously looked at

It is disappointing on waiting for an order and it arrives as damaged. I will have our customer service team reach out to you.



by:

Package arrived on time, box the spindle came in was damaged and you can clearly tell the spindle was out in the elements. However, shipping was timely, faster than expected truth be told. Just cannot look past the fact the spindle almost looked like a used spindle and the box it came in was damaged. Other than that I am satisfied.



by:

Ashley was extremely helpful and made sure I was getting exactly what I needed and followed up when the shipper had a delay in shipping product.



by:

Great deal on a great product



by:

Great quality. But it is 1/4 in" to small. No worries I am a welder and fabricator. I already made a sleeve to make up the difference. Have been using etrailer for years, not gonna let a little thing like this stop me from future purchases. I know I could get a replacement without any hassle, but I don't have time to wait. If it were for a customer than yes, I would get a replacement. But it's mine, and like I said I know how to weld (55 years). Thanks Gary



by:

I had to have sleeves made at a machine shop order to make these spindles work. I was told over the phone that these were the correct size to fit my Ram-Lin trailer for my 2001 Ski Nautique. Buyer beware!

Spindle worked perfect on Dexter 7k axle. Thanks

  • Can Spindles be Replaced on Dexter Torflex Axle
    The spindles can be replaced. However, they will need to be welded by a certified welder. They use special jigs so that it is concentric and square on the axle or it can cause problems with uneven tire wear and wheel tracking. I've linked our selection of spindles for your to find the correct part for your trailer.

  • Hub And Bearing Replacement For A 5,200 LBS. Mobile Home Axle
    I do have a hub and bearing assembly that will allow you to replace the hubs on your mobile home axle however, mobile home axles are intended for a one time single use only, therefore there is a limitation to readily available replacement parts. When changing the hubs and bearing on a mobile home axle it is important to note the condition of the spindle. A discoloration or nicks/scarring on the spindle are a good sign of needing a replacement. Installing new parts on a damaged spindle...

  • Will The Dexter K23-532-533-00 Brakes Fit A #42 Spindle?
    Hello Pat, thanks for reaching out. The # K23-532-533-00 brakes you mentioned are for an 8K Hayes/AL-KO axle with a 4-bolt brake flange. The # 42 spindles like part # TRU37FR are 7K rated and have a 5-bolt brake flange, so these parts would not be compatible. I was not able to find any reference for the 8-187 hub you mentioned. What parts are you looking for exactly? If you are needing brakes for a # 42 spindle, those would be part # AKEBRK-7-SA. Leave a reply below and let me know...

    Hey Ashton, They #42 spindle # TRU37FR and the idler hub # AKIHUB-865-7-2-EZ-K are going to work well together. The idler hub is designed specifically for that #42 spindle. Unfortunately we do not have any .STEP files for these parts, just the photos we have on the site. What kind of trailer are you looking to do the work on?

  • Length Measurements for EZ Lube Spindle 2.25
    I went out to the warehouse to take some measurements of trailer spindle # TRU37FR for you. The stub is actually 3-3/8 inches from the end to the brake flange. It is 3 inches from the end to where the weld is for the brake flange. The brake flange itself is a hair under 1/4 inches thick. The distance from the flange to the tip of the grease fitting is 7-1/2 inches. But to the end of the threaded part it is 7-1/4 inches. The overall length from tip to tip is approximately 11-1/8 inches....

  • Trailer Hub & Spindle For 7,000 lb Axle With 12 Inch Electric Brakes
    First, thanks for all that detailed information, it was very helpful. And we can get you parts for your trailer, though the issue is that there isn't an available hub for your spindle due to what you mentioned - the uncommon 501349 bearing, which is for older agricultural spindles. There also isn't a 7,000 lb-rated hub with a 6 on 5-1/2" bolt pattern to go with your 7k-rated Dexter Nev-R-Adjust Electric Trailer Brake Assembly # 23-464 and # 23-465.

  • Replacement Straight Axle Spindles For the Lippert Axle On a 2019 K-Z Sportsmen Classic 180TH
    I have an option that may work out for you as we do not have any axles that will have the same hub face dimensions as your Lippert axle in your 2019 K-Z Sportsmen Classic 180TH. You can have your drop spindle that is currently welded on your Lippert axle cut off and replace it with a #42 E-Z Lube Spindle w/ Flange # TRU37FR straight spindle. This spindle has the same dimensions as your current Lippert axle so you will still be able to use your current hubs and brakes. You can get the...

  • Replacement Hub/Drum and Brakes for a TetonX Trailer
    Yes, the 12" Dexter Electric Trailer Brakes - Parking Brake Ready # 23-112-113 and the Dexter Trailer Hub and Drum Assembly 6 on 5-1/2 # 8-201-9UC3-EZ are an excellent combination for your TetonX trailer. Unless your spindles are in bad shape I'd leave them alone. Usually when spindles look like they need to be replaced it's because some major damage has happened and a lot of times the whole axle being replaced isn't uncommon. Should you decide to have a spindle (or a few of them) on hand...

  • Does Axle of Trailer Need to be Removed to Install New Spindles
    Hey Rico, so installing a new spindle does take some special equipment to ensure you get the alignment right. You probably don't have to take the axle off but I would call around to local welders/fabrictors to you and ask if they have the needed jigs to install an axle spindle and once you find one who does you'd be set. That said..I can't believe someone thought it was a good idea to weld the spindle nut on!

  • Parts Needed To Add Brakes To An Axle
    Hi Jason! We definitely have what you are needing, but do you know what the bolt pattern of your wheels is? Guessing it's a 5 on 4-1/2, but I recommend checking if you are unsure (I included a picture that shows the easiest way to check). That 4 bolt pattern you have on the brake mounting flange means you have a 3,500 pound axle, so I would be surprised if you have a different bolt pattern. If you do have that 5 on 4-1/2 bolt pattern, the Easy Grease Trailer Hub and Drum Assembly for...

  • Number 42 Spindle Recommendation for Mounting Trailer Hub for Spare
    If you can get me more info on the hub I can see which spindle it would fit. If you know the bearing numbers of the hub that would work, or there is a casting number on the hub like what Dexter does that would work. Axle capacity of the trailer will work as well.

  • Replacement Spindle and Hub/Drum that Fits Lippert 5,200 lb Trailer Axle
    Hey Ethan, while I don't know exactly what info you are looking for I can tell you that the #42 spindle you have referenced part # TRU37FR is correct for a 5,200 lb axle. Then for a hub/drum you'd want the part # AKHD-655-6-K. Are you in need of brake assemblies too?

  • How To Remove Spindles From Trailer Axle
    Trailer spindles are welded directly to the axle so to remove one it just needs to be cut off completely using a torch or saw. Then to replace the spindle such as with the EZ Lube # TRU37FR that you were looking at it's extremely important that it be done by a certified welder who is experienced with this type of job. It has to be welded perfectly square to the axle or you're going to have constant problems with the trailer's suspension once everything else is put into place. Because...

  • Grease Cap for Kodiak KHR1389D and Spindle for 2021 Forest River Riverstone 39RKFB
    Hello Jonathan; the correct grease cap for the # KHR1389D is the Replacement Grease Cap for Kodiak 7,000-lb, 7,200-lb, and 8,000-lb Disc Brake Kits # KPCAP. The hub and rotor are designed for 7,000 - 8,000 lb axles. Our spindles only go up to 7,000 lbs so if you have an 8k axle we don't have one with a high enough rating. Otherwise you can use the #42 E-Z Lube Spindle w/ Flange for 5.2K to 7K Trailer Axles # TRU37FR. If you aren't sure, the capacity should be listed on the axle tag.

    Hey Andrew, do you know what capacity your trailer axle is? With that I can see what would be the correct replacement spindle would be. Most likely it's between 5,200 and 7,000 though and you'd need the part # TRU37FR.

    Hey Craig. The #42 E-Z Lube Spindle w/ Flange item # TRU37FR, you were looking at, has a 1"-14 thread size. This spindle fits 5,200-lb - 7,000-lb trailer axles. It has a 5 bolt brake mounting flange. The distance from the flange to the tip of the grease fitting is 7-1/2". To the end of the threaded part is 7-1/4". What kind of trailer do you have?

  • Recommended Replacement Spindles for a Dexter Trailer Idler Hub Assembly W/ a 6 on 6 Bolt Pattern
    Hey Steve, the #84 Spindle for 3,500-lb Trailer Axles # TRU64FR is not going to work with the Dexter Trailer Idler Hub Assembly for 6,000-lb Axles # 42660UC1. You'd actually want to use either the #42 Spindle for 5,200-lb to 7,000-lb Trailer Axles # TRU57FR or the #42 E-Z Lube Spindle w/ Flange for 5.2K to 7K Trailer Axles # TRU37FR for an E-Z lube spindle.

  • Parts Needed To Install 6 on 5-1/2" Brake Hub/Drums on a M1101 Military Trailer
    First you are going to want to disassemble one of your hubs to verify if you have the #42 Spindle # TRU37FR. I have found this is the spindle some have found but you will need to determine it is what you have and if not you will need to have a pair of the spindles welded onto your axle. This will then allow you to install the Electric Brakes # AKEBRK-7-SA along with the 2 of the 6 on 5-1/2" Drum/Hubs # AKHD-655-6-EZ-K. The hubs are complete with bearings pre-greased and seals inserted in...

  • Replacement Trailer Axle For 93" Hub Face To Hub Face Measurement
    The Trailer Axle Beam # e93GR is the closest axle we have to the 93" hub face to hub face measurement you are looking for. It has a 94" hub face to hub face measurement. While the spring center on this axle is 79" you can have new Spring Seats # TRSS300 welded at the 76" you need. This axle is rated for 7,000lbs but will use the same #42 Spindle # TRU37FR and brake flange as the 6,000lb axle allowing you to use it. If you will not be able to use this axle due to the hub face difference...

  • Replacement Spindle Recommendation for Dexter # 42
    Looks like you are in need of a number 42 spindle like the part # TRU37FR. The numbers you listed aren't part numbers but judging by the shape of what you sent in a picture of this is a match. You still might verify this though by measuring where the bearings ride. If those dimensions are 1.25 and 1.74 inch then this is the correct.

  • How Will The Spindle Need To Be Removed On a 7,000LB Torsion Axle?
    The Spindle # TRU37FR is going to be welded in place on your torsion axle. It will most likely need to be cut off and torched out due to the way your axle is clocked near the mounting bracket. Before you attempt to replace the spindle be sure to check the condition of the rubber inserts inside the axle as you may need to consider replacing the entire axle if there is to much free play on your axle. As we do not carry replacement torsion axles you might consider a Timbren Axle-Less system...
