  • 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...

  • 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....

  • 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.

  • 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...

  • 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.

  • 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...

  • Replacing a Spindle on an Enclosed Trailer Axle

  • 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.

  • Is Broken Zerk Fitting of Trailer EZ Lube Spindle a Problem
    Actually it looks like your spindle had a standard zerk fitting on it at one point and it was possibly removed on purpose or accident. We don't have a way to install a new one. Honestly though you are better off without using this type of EZ lube setup. Repacking the bearings with grease by hand will give you the best results and won't risk you over-greasing the hub and blowing out the grease seal. I have linked a video to the right that shows how to pack trailer bearings. Be sure to...

  • 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.

  • 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...
