Ask the Experts about this TruRyde Trailer Spindles

  • Replacement Zerk Fitting Recommendation for Dexter EZ Lube Spindle
    I confirmed with my contact at Dexter Axle that the grease zerk used in their EZ Lube spindles like # TRU74FR is a standard 1/4-inch pipe thread fitting that you can replace with an item like # Gzerk. Your local hardware store may have one too. You can use a grease gun kit like # L30132 on this fitting.

  • How to Pick Out Replacement Axle for Older Trailer
    We don't have a way to look up what axle/hubs your trailer needs by the VIN but we can help you determine what you'd need. The first thing you need is the capacity of the axle. You'll also need to know the axle length. I've attached a photo showing where to measure your axle for the correct length. I've also included a link to our axle product listings. Once you know your measurements, you can use the filters on the left side of the page to choose the correct axle. Or, if you'd like, you...

  • Is The EZ Lube Spindle # TRU74FR Compatible With 10 Inch Brakes
    I contacted our representative at TruRyde about the EZ Lube Spindle, part # TRU74FR, and he confirmed that it will work for 10 Inch brakes. I would recommend having a trailer professional install part # TRU74FR, as it requires precision welding. The spindle will need to be welded square and concentric to the axles so the brake will fit and operate properly in the hub.

  • Replacement Spindle for 1996 Yacht Club Trailer
    We do offer replacement spindles for trailer axles that can be seen using the link provided. You will want to match the axle capacity (look for a sticker or plate on the axle itself) and its shape and dimensions, including length and diameter. Trailer spindles must be installed by a qualified professional welder. Spindles must be welded on perfectly concentric or you will have tracking problems. A trailer shop will have the right jigs to allow the spindle to be welded on correctly. I...

  • Greasing Trailer Axle Spindle Where Zerk Fitting Broke Off
    What I would recommend you do is extract as much of the old zerk fitting as you can and then going forward grease that hub by hand and you'll be totally fine if not better off than using the grease fittings. It's pretty easy to overfill EZ lube spindles and blow out the grease seal of the hub so if you grease the hubs by hand you'll avoid that and be in good shape. I have linked a video to the right that shows how to pack trailer bearings.

  • Spindle Recommendation for a Square 2x2 Axle
    For your 2 inch by 2 inch axles you would want a Redline Spindle for Square Axles # TRU47FR. This is a square spindle designed for 2 inch square axles so it should work for well for you. Check out the review video I attached. The EZ Lube Spindle # TRU74FR you referenced is designed for round axles so it would not work for you. Spindles should be welded on by a qualified welder.

  • Do My Wheels Need to Be Removed to Grease Bearings If I Have EZ Lube Spindles
    If the wheels on your trailer don't allow you access to the EZ lube spindles like the # TRU74FR, you do need to remove the wheels. If you've got access to the grease zerk on the spindle though, you do not need to remove the wheels; it really just depends on the type of wheel you've got on your 2013 Rockwood Pop-Up camper. If you need grease, you can use the LubriMatic LMX Industrial Strength Grease # L11390.

    You are going to need to measure your current axles in a few places to get the correct one as we don't have a way to look up what you might need. You will need to measure from hub face to hub face and then from the spring seat centers. You will also need to know what bolt pattern you have on your current hubs. I attached a help article on how to determine this as well. I also attached a link to a page with all of the axles we carry. If you don't see the size you'd need you may need...

  • Need Brake Flange For Adding Brakes to Homemade Trailer
    Since your hubs are for 5200-lb axles and you've confirmed that you do have a 3" diameter axle, you'll need the Redline 5 Bolt Flange # 4-44-1 . You should know, if you don't already, that brake flanges need to be welded perfectly concentric. For that reason we generally recommend that the work be done by an experienced trailer shop that has the required jig. To add brakes to your axles you'll need a couple additional parts- brakes and a hub and drum assembly. For brakes I recommend...

  • Benefit of E-Z Lube Spindles for Easier Wheel Bearing Lubrication
    Using a grease gun on the zerk fitting of an E-Z Lube spindle like # TRU74FR can make it all too easy to over-fill the hub grease level. Care should be taken to avoid the risk of blowing out the inside grease seal. For such applications a double-lip seal is recommended since it will be less likely to suffer failure and leak grease everywhere. Using E-Z Lube spindles/grease caps makes for an easier time topping off the wheel bearing grease level. But the same routine maintenance is still...

  • Available Sizes of Trailer Axle Spindles
    TruRyde EZ Lube Spindle # TRU74FR does include a brake mounting flange already welded in place. The linked page displays all of our spindle products which include square-stub spindles without brake flanges like # TRU47FR. We do have 1-3/4-inch spindles but note these all have a round stub end, not a square stub. Spindles should be selected based on the axle's weight rating. This ensures the spindle has enough capacity to match the axle.

  • Replacement Trailer Spindles to Allow Installation of Different Hubs
    All of the trailer spindles we sell are weld-on types, including those with brake flanges like TruRyde # TRU74FR that fits 1.75-inch diameter axles. The largest diameter spindle we sell is for a 2-1/4-inch axle beam, part # TRU37FR; this can be seen on the link provided. This spindle is for a 5200-lb axle and it has a 5-bolt brake mounting flange. It is almost surely going to be easier and less expensive for you to replace your axles than to have a professional welder install new spindles...

  • Compatibility Of 3500 lb EZ Lube Spindles And Dexter Hub Assemblies
    The #84 EZ Lube Spindle # TRU74FR is compatible with hub assemblies # 84655UC1, however I recommend you use the Trailer Hub Assembly - 3,500-lb Axles - 6 on 5-1/2 - E-Z Lube # 84655UC1-EZ instead for easier access to your EZ Lube Spindle.

This is measured from the base to the end of the threaded portion as shown in the attached video. The TruRyde item # TRU24FR is the closest #84 spindle we have to what you need. It measures 8-1/4 inches overall, but it's 2 inches in diameter and it doesn't come with a brake flange welded to it. You could use part # 4-35 as long as your current hub and...

  • Can a Trailer Axle be Converted to an EZ Lube Axle by Replacing Spindles
    To upgrade to an EZ lube setup will require you to replace your axle or you could just replace the spindle. For a spindle with a 4 bolt mounting plate you would want the part # TRU74FR as it is an ez lube spindle. For a new hub/drum to fit this you would want the part # AKHD-545-35-EZ-K or for a idler hub part # AKIHUB-545-35-EZ-K. Welding a spindle is not something we recommend most people doing. Most axles have these welded on at the factory with specialized jigs and higher precision...

  • Can Oil Bath Trailer Hub Easily be Converted to Grease
    It's totally fine to replace the oil in an oil bath hub with grease without changing anything else. The bearings will be properly lubricated and the seals will work just fine. I actually prefer grease to oil bath hubs mainly because if for some reason the seal of the hub goes out an oil bath hub is immediately done since all of the lubrication drains and by the time you notice the bearings have gotten way too hot, whereas with grease (since it's not a liquid) you can normally get home easily...

  • Correct Wheel Bearings and Races for 3,500 lb Axle Based on Spindle Diameter?
    The spindle dimensions you gave match up with # TRU74FR. This spindle is for use with 3,500 lb axles. Based on this, we can tell you that the appropriate bearings are inner # L68149 and outer # L44649. The correct races are inner # L68111 and outer # L44610. When replacing bearings, the grease seal often needs to be replaced as well, and the proper one for this is the Grease Seal for 3,500-lb Axles, # 58846.

  • How Does The EZ Lube Spindle # TRU74FR Work On A Boat Trailer
    On the EZ Lube Spindle # TRU74FR you do not need a grease fitting for the hole on the inside end of the spindle. This is an EZ lube spindle which is designed to allow you to put grease onto the bearings by using the zerk fitting on the threaded end of the spindle. You will not want to block the hole that is on the inside end of the spindle. When the hub is installed on the EZ lube spindle it will form a cavity around the wheel bearings and when you pump grease into the spindle through...

  • How to Fix a Pitted Spindle
    Unfortunately, we do not sell spindle repair sleeves. However, the best way to repair a pitted spindle is to replace the whole spindle or axle. If you are interested in replacing your spindle, you can give me the spindle product number, or I will need to know a few measurements to recommend a new one. You will want to use a digital caliper like # PTW80157 to get the most accurate dimensions. The spindle measurements are labeled A through F, please view the diagram as a guide. A...

  • Could Zerk Fitting be Added to Trailer Spindle to Make it an EZ Lube Spindle
    EZ lube spindles are more than just a zerk fitting attached to the end of the spindle. There would need to be a hole in the spindle between where the bearings ride for the grease would then fill the hub by. To be perfectly honest using EZ lube spindles or Bearing Buddies typically causes people to over fill their hubs and blow out the grease seal so you're better off packing the hubs by hand. I attached a link to a bearing packing video for you to check out as well.

  • Replacement Bearings and Bearing Buddy Protectors for 2008 Yacht Club Trailer
    I contacted Yacht Club Trailers and was able to track down the correct inner and outer bearings for your 2008 model trailer using the VIN you provided. The spindle on your trailer uses the # L44649 bearing (1.063 inner diameter) for both the inner and outer bearing. For a complete kit that includes the races and grease seal you can use # BK1-150. Most likely the correct Bearing Buddy size is the part # BB1980A, which fits a 1.980 inch hub bore. I recommend taking a quick measurement...

  • Which is Better an EZ Lube Spindle or a Bearing Buddy Setup
    An EZ lube spindle will be better because it allows you to insert grease from inside the spindle where the bearings are and push out the old grease whereas with a Bearing Buddy you basically just get to push grease through the front of the hub. I attached a link to a page that has all of the EZ lube spindles we carry. The advantage to a Bearing Buddy would be that it would be much easier to install since they basically just replace the grease cap whereas with a new spindle you have to...

    Yes, you should have no problems using an Oil Bath System, like part # XLPROLUBE1980KIT, with a number 84 EZ Lube Spindle, like part # TRU74FR. A few things to keep in mind when installing an oil bath system. You will want to make sure that everything is sealed up properly because oil is a liquid and if you have a major leak you will lose your lubrication. When you install the body and cap you will need to make sure that it is installed all the way in your hub and is not crooked. If...

  • Grease Coming Out of EZ Lube Trailer Spindle
    There are only 3 ways that grease will come out on an EZ Lube axle. 1) You pump it in and it oozes out of the hole in the shaft to lubricate the bearings (normal operation). But you wouldn't see it because the hub/drum would be installed 2) It comes out the back of the hub meaning you blew a seal (seal needs to be replaced, use double lip seals) 3) It comes out where you are pumping it in because the hub/drum is full (if you see new grease then you are good to go) When adding...
