See what our Experts say about this TruRyde Trailer Spindles

  • Replacing a Spindle on an Enclosed Trailer Axle
    When replacing the spindle on your trailer with a EZ Lube Spindle, part # TRU74FR, you will need to cut off the existing spindle and weld a new one in place. I strongly recommend you take it to a qualified machine shop to have the appropriate welds done.

  • 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.

  • Spindle Recommendation for a Broken Zerk Fitting on a Spindle
    I spoke with my contact at Redline and he informed me that there is a replacement zerk fitting for your spindle but that it is not the same as one you would see on a tractor or anywhere else. It would be a special order item that we would need to order from our distributor. Or you could replace the spindle. If this EZ Lube Spindle, part # TRU74FR, has the same dimensions as the spindle that is on your trailer now this would be a good replacement. You will want to use a dial caliper to...

  • Replacement # 84 Spindle Recommendation to Replace a Trailer Spindle
    It looks like you cut the spindle off but left the brake mounting flange on your trailer. I would recommend you cut off the entire spindle and have a qualified trailer fabricator weld on the EZ Lube Spindle # TRU74FR as long as your brake assemblies are compatible with the 4 on 4-13/16 inch bolt pattern flanges of this spindle (it should). Is your hub okay? If you email me back with the bolt pattern of the wheels of your trailer and the diameter of your brake assemblies I will recommend...

  • Replacement Spindle Recommendation for a 1988 Tandem Axle Shorelanr Boat Trailer
    Since the diameter of the spindle where the outer bearing rides is 1-1/16 inches most likely you have a number 84 spindle. You will need to verify that where the inner bearing rides is 1.38 inches and where the seal rides is 1.73 to be sure though. If so, the correct spindle would be the part # TRU74FR.

  • 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...

  • How to Measure to Pick Out Replacement Axles for a Trailer
    I wish there was an axle database that I could look your VIN up and see what you would need. You are going to need to measure your current axles in a few places to get the correct one. 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.

  • Can Manual Adjust Brake Assemblies be Replaced with Self-Adjusting Assemblies?
    Yes, you can replace a set of manual adjust brake assemblies with self-adjusting ones. You would just need to know the size of the brakes that you have now, the axle capacity, and what bolt pattern mounting flange it has so that you can pick out the correct assemblies. Very common sizes are 10 by 2-1/4 inch and 12 by 2 inch. Once you know what size you have you can check out the link I attached that has all of the self-adjusting assemblies we offer. I also attached a picture that shows...

  • 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...

  • How to Find Replacement Bearing Info For Older Trailer
    The best way to find the correct replacement bearings is to get the numbers stamped onto the metal of the inner and outer bearings that are currently on the trailer. With those you will be able to find the correct replacement bearings, races, and seals. Another option is to measure the spindle of your trailer with a micrometer to get the diameter of it where the seal, inner, and outer bearings ride. See picture.I have included a link to a video on inspecting trailer bearings that should...

  • Grease is Leaking From the Back of the Hub at the Seal Rather than at the Front
    It is possible that you have single lip seals and need to replace them with double lip seals to avoid the grease leaking from the back of the hub. A double lip seal will have a stronger seal for EZ lube spindles such as # TRU74FR. The force of the grease being pumped in is too much for single lip seals to handle. Also, if using a powered grease gun, whether if it is electric or pneumatic, can also create too much pressure even for a double lip seal. If you can tell me the seal number you...

  • Replacing Damaged Axles and Spindles on a Yacht Club Trailer
    In order to determine which replacement axles you need, I will need a few measurements. I will need hub face to hub face measurement, spring center to center dimension, inner and outer wheel bearing reference number, and the axle capacity. Take a look at the diagram I included. Regarding replacement spindles, you will want to use a dial caliper to measure the dimensions of your spindle for me to recommend a new one. The spindle measurements are labeled A through F, please view the diagram...

  • Who Can Replace a Trailer Spindle
    Trailer spindles should only be installed by a qualified fabricator with trailer axle experience who has the necessary equipment to square up a trailer spindle. It's not a project for someone who's pretty good at welding since if the spindle is off by just a little bit you will have all sorts of alignment issues.

  • Troubleshooting Zerk Fitting on Trailer Axle that Wont Accept Grease
    Since the zerk fitting of your spindle is clogged and the fittings of most spindles are hard to remove and replace you can try taking the trailer to a local trailer shop to you that has experience working on axles to see if they can unclog it. One easy solution would be to break of the zerk fitting and replace your grease cap with a Bearing Buddy. In order to pick out the correct bearing buddy you will need know the pilot hole of your hub. To do this, remove the wheel and tire and remove...

  • Easy Way to Grease a Hub that is Missing EZ Lube Zerk Fitting
    If it's missing the zerk fitting the easiest solution I could recommend for you would be to replace your grease caps with Bearing Buddies. Bearing Buddies replace the grease cap and provide an easy way to grease hubs. In order to pick out the correct bearing buddy you will need know the pilot hole of your hub with a dial caliper. To do this, remove the wheel and tire and remove the grease cap from the center of the hub. Usually it is a metal cap that is just lightly hammered into place....

  • 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...

  • 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...

  • Design of EZ-Lube Spindles to Allow Grease to Reach Inner and Outer Bearings
    I think you may be referring to the spindle that is installed on your trailer axle. The spindle is the part such as # TRU74FR which has a grease zerk fitting on the spindle's end. This grease fitting allows you to fill the hub bore and both inner and outer bearings with grease without having to remove the hub to pack the bearings by hand. If you have this type of EZ-Lube spindle you do not also need to use Bearing Buddy bearing protectors like those mentioned in the question you reviewed....

  • Acceptable Range of Spindle Deflection on Torsion Axle
    Torsion axles can have different spindles with varying geometry. The specific spindle installed will have a specific range of deflection angle. The spindles on torsion axles can deflect as much as 4-inches between the unloaded and loaded conditions. A 1-inch height drop suggests you are well within the axle capacity and that it is not worn out.

This would fit standard 3,500 lb hubs as well. Trailer spindles should only be installed by a qualified fabricator with trailer axle experience who has the necessary equipment to square up a trailer spindle.

  • Troubleshooting Slight Amount of Grease Leaking from E-Z Lube Spindle
    Any grease on the back of the wheel could be from the grease working its way out from having slightly too much or it could be from a grease cap or grease seal that is not fitting properly. The grease cap and seal should be keeping any excessive grease off the wheel unless the parts are failing. I recommend pulling the rubber plug to see if there is grease inside and if so just clean the wheel and keep your eye on it for more. If it keeps happening, something is not working correctly...

  • Greasing E-Z Lube Spindles on Trailer
    It sounds like your you have E-Z Lube spindles on your trailer that feature grease zerk fittings at the ends of the spindle. Adding grease to the spindle and bearings is just a matter of using a grease gun like what it sounds like you have done. The spindle will have a hole in it so that it fills the hub components from the back of the inner bearing with grease as you pump grease into the fitting. You will want pump the grease slowly while occasionally rotating the hub so as to prevent...

    The measurements that you are referring to (listed below) are the actual diameter of the axle itself. By shaft size I am guessing you are referring to the spindle? The spindle actually doesn't go all the way through the axle as you can see when you look at a replacement spindle like part # TRU74FR. Typical Axle Diameters Based on Axle Capacity 1,000-lb - 2,000-lb Axles: 1-1/2 inch - 1-3/4 inch diameter 3,500-lb Axles: 2-3/8 inch diameter 6,000-lb - 7,200-lb Axles: 3 inch diameter 8,000-lb...
