  • Distance From End of Spindle to Face of Brake Flange
    The distance from the end of the spindle to the face of the brake flange on the #84 E-Z Lube Spindle w/ Brake Flange # TRU74FR is 5-3/8". See the diagram below which shows this measurement.

  • How to Determine Correct Replacement Trailer Hub and Spindle
    We can get your trailer rolling again, and to get the correct replacement hub and spindle, you will just need to take a look at a couple things and get some measurements. You will need to take apart your current hub assembly and look at the bearings themselves; wipe away the grease and you should be able to see the part number stamped directly on them. If you are unable to find them, you need to use digital caliper and measure your spindle to the thousandths of an inch where the bearings...

  • 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...

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 Pick Out Hub/Bearings and Leaf Springs for 2003 Yacht Club Trailer
    I really wish it was that easy, but we don't have a way to look up the VIN of a trailer and determine what axle the trailer had. In order to pick out the correct hub assembly for a trailer you are going to need know a few key pieces of information. The first thing you will need to know is the bolt pattern of your hubs. This is so you get a hub that is compatible with your wheels. I attached an FAQ article on determining bolt pattern for you to check out. Next thing you will need to know...

Your trailer VIN will not tell us which spindles you need but you can select the right one based on your axle's weight rating and measurements of the current spindle. You'll need a digital caliper like to measure precisely. Note that new spindles should be welded on only by a professional welder who has experience and the correct jigs for installing spindles...

  • 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.

    I wasn't able to find anything in regard to a replacement part for your TDE 11029C hub assembly, but if you can pull your hub and either look for bearing/grease seal parts numbers or measure the different locations on your spindle then I can see if something matches. To measure your spindle, you'll want to use a digital caliper and measure the locations in the attached photo to the 3rd decimal (1.234 for example).

    The #84 E-Z Lube Spindle w/ Brake Flange for 3,500-lb Trailer Axle - 1-3/4" Diameter # TRU74FR you were looking at has a 4 bolt mounting flange that has holes 2-7/8" apart on center, and from the outside edge of the flange to the end of the spindle is 3-1/4" as shown in the included diagram. This spindle will work perfectly with a 10" rotor. I included a video of the # TRU74FR for you to take a look at.

  • 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...

  • Will Overheating a Trailer Hub Damage the Spindle
    If the spindles were overheated due to a bearing malfunction then you will need to replace them or the axle. The spindles are already heat treated for strength but you will lose that strength if heated beyond a certain point after the fact. If there are any discolorations on the spindle (usually blueish) then that would indicate heat damage. If you can let me know what size axle you have and the shape I would be glad to see about getting you replacement spindles if applicable but most cases...

  • 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.

  • What Info Is Needed to Get Replacement Spindle for Horse Trailer
    I would need you to get me the dimensions of your spindle to see if we have a match here. I would need the diameters of the spindle where the bearings and seal rides. For example, the EZ Lube spindle part # TRU74FR is a very common replacement for 3,500 lb trailer axles and has bearing dimensions of 1.06 and 1.378 inch and seal diameter of 1.719 inch.

    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.

  • 3,500 lb Spindle Recommendation for Boat Trailer
    We do not have the axle you are looking for, but we do have 3,500 lb spindles that may be just what you need. The part # TRU74FR is an EZ lube spindle with a 3,500 lb capacity. 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. It's not a project for someone who's pretty good at welding since if the spindle is off by just a little...

  • Is it Normal for Grease to Leak Out of EZ Lube Grease Cap
    One of the big issues that EZ lube spindles create is that it's too easy to put too much grease into them which then either causes the seal to blow out or the cap to leak like what you have found. This oftentimes happens after that first trip like what happened to you. I don't actually recommend using the EZ lube fitting to add grease and instead recommend just packing it all by hand and leaving it as-is. In your case I would recommend pulling the hubs off and making sure the seal is in...

  • Replacing a Spindle on an Enclosed Trailer Axle

  • 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.

  • How To Determine If Trailer Brakes Could Be Added?

However, in order to determine what brakes you can add to your trailer, you'll want to first verify if your trailer has brake mounting flanges like # TRU74FR. If your trailer does not have brake mounting flanges, then you will need to have them precisely welded on by a professional, however it is much easier to have the entire axle replaced with one that does have a brake flange already welded.

  • 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 grease...
