Expert Answers about Trailer Spindles


  • Which Spindle Height of Timbren Axle-Less Trailer Suspension for Car Trailer
  • The drop spindle model you mentioned, part # A35RD545E would be used over the straight spindle model, part # A35RS545E if you wanted a lower deck height on your car trailer. Since you are most likely already using ramps, I cannot see how you would benefit from further lowering the trailer deck height. The straight spindle model would place your spindle center about 4 inches below the mounting surface of the unloaded trailer. The drop spindle model would place the spindle center about 1/4...

  • Are the Trailer Grease Seals 168255TB and 171255TB Interchangeable
  • The two seals you mentioned are pretty close in size but the part # 168255TB has a slightly smaller inner diameter. In nearly all cases for trailer spindles the correct seal would be the part # RG06-050 (171255TB) since trailer spindles will typically have an outer diameter of 1.73 inches. The slightly tighter seal could maybe work in but the best way to tell is to measure the spindle where the seal rides. If its 1.73 the 171255TB is the correct one.

  • Comparing 95" Trailer Axle Beam with Easy Grease Spindles and Dexter Trailer Axle Beam with E-Z Lube
  • The Trailer Axle Beam with Easy Grease Spindles part # e68GR is made by Axle Tek and the Dexter Trailer Axle Beam with E-Z Lube Spindles part # 7359765 is made by Dexter. That said, they both have the same specs and features, you'll just save a bit of money with our house brand so that's what I recommend. That said, if you want to stick with the name brand item in Dexter, you won't be disappointed there either.

  • What Makes 5200lb and 6000lb Dexter Axles Different Capacity?
  • The thickness of the tube is not any different as they are both 3 inch diameter, and the spindles are also the same utilizing the same inner diameter bearings, hubs, and seals. The difference in capacity is in the custom bend in the axle that creates the zero camber angle for even road to tread contact. To the naked eye there is no difference between the Dexter Trailer Axle Beam with E-Z Lube Spindles - 95" Long - 6,000 lbs # 7461121 and the Dexter Trailer Axle Beam with E-Z Lube Spindles...

  • Comparing Timbren Axle-Less 2K Trailer Suspension Systems with 4" Lift
  • Great question! The Timbren Axle-Less Trailer Suspension System # ASR2KHDS04 has a standard size spindle which is why it is for regular tires. The Timbren Systems # ASR2KHDS03 and # ASR1THDS03 have longer spindles which can accommodate wider tires and the only difference between them is the slightly higher weight rating of the part # ASR1THDS03 (also known as the 1 Tonne by Timbren). All 3 kits are great options for off-road use because of the 4" lift, so it really boils down to what...

  • What is the Difference Between Trailer Hubs # AKIHUB-440-2-G-1K and # AKIHUB-440-2-G-2K
  • The two hubs you mentioned, # AKIHUB-440-2-G-1K and # AKIHUB-440-2-G-2K fit different spindles. More specifically they use different bearings and seals. First, hub # AKIHUB-440-2-G-1K uses L44643, with a 1 inch inner diameter, as the inner and outer bearing, and the seal is a 34823, which has an inner diameter of 1.249 inches and outer diameter of 1.983 inches. Based on your information this sounds like the correct replacement. Check your old bearing numbers or you can take measurements...

  • Comparing Timbren Axle-Less Suspension for Standard Tires and Wide Tire Applications
  • The Timbren Axle-Less Trailer Suspension System - Spindle w/Brake Flange - Regular Tires - 2,000 lbs # ASR2000S02 is a suspension system integrated into a spindle that can use a 2 inch square bar to created an axle of whatever length needed. The Timbren Heavy-Duty Axle-Less Trailer Suspension - Straight Spindle - Wide Tires - 2,000 lbs # ASR2KHDS02 is basically the same system with a wider base prior to the brake flange and spindle to account for a wider tire. It will give you 8-1/2 inches...

  • Tang Washer for E-Z Lube
  • From my research it looks like the Dexter 005-101-00 are tang washers for E-Z lube spindles before 2002. While that's not the specific application of Replacement Spindle Washer - Tang Type for E-Z Lube # 5-101, this part may still work for you. The # 5-101 washer has a 1" inner diameter and will fit on 1" diameter spindles. I've added a link to a video review of this part for you to check out as well.

  • Comparing CE Smith Trailer Hub Assemblies CE13100 and CE13110
  • Yes, the CE Smith Trailer Hub Assemblies # CE13100 and # CE13110 will both fit on a BT8 Spindle # TRU94FR. The only difference between these 2 hubs is the Hub Assembly # CE13100 is threaded for wheel bolts and the Hub Assembly # CE13110 has wheel studs and lug nuts.

  • Comparing the E-Z Lube Hubs to the Standard Hub Assemblies for Trailer Axles
  • The difference between the standard and EZ hubs is in the grease cap. For instance, the Trailer Hub and Drum Assembly - 3,500-lb E-Z Lube Axles # AKHD-545-35-EZ-K is the same hub, bearings, seal, and races as found in # AKHD-545-35-K but the grease cap is different. The grease cap is not only longer on the E-Z Lube Hubs but also has a rubber plug. The purpose of the length and the plug are to have enough room for and access to the grease zerk fitting integrated into E-Z lube axle spindles....

  • Availability of 4 on 4 inch Bolt Pattern Hubs for a Spindle with 1 inch Inner and outer Bearings
  • Yes, we have the Trailer Hub Assembly for 2,000 lbs Axles with 4 on 4 inch bolt pattern, and 1 inch inside diameter bearings, item # AKIHUB-440-2-1K. You should check the existing bearing part numbers on your trailer to be sure that they are the # L44643 inner and outer bearings. Your seal part number should be # 34823, with an inner seal dimension of 1.249 inches. The hub you referenced has 1-1/16 inch inside diameter bearings, and would not work on a 1 inch spindle. The bearings for...

  • Comparing Trailer Idler Hub Assembly for 3,500-lb Axles AKIHUB-545-35-K and AKIHUB-545
  • The only difference between the Trailer Idler Hub Assembly for 3,500-lb Axles part # AKIHUB-545-35-K and part # AKIHUB-545-35-EZ-K is that the latter is for axles with grease zerks in the end of the spindles i.e. EZ-Lube.

  • Available 3,500 lb Timbren Axle-Less System Without Electric Brakes
  • There is a Timbren Axle-Less Trailer Suspension System similar to # A35RD545E but does not have electric brakes. The # A35RD545 has the same 3,500 lb capacity with a 4" drop spindle and idler hubs. The hubs have a 5 on 4-1/2" bolt pattern with inner bearing # L68149, outer bearing # L44649 and grease seal # RG06-050. I've added a link to a video review of the Timbren Suspension System for you to take a look at as well.

  • Difference Between Hub/Drum # 8-219-4UC3-EZ and # 42866UC3-EZ
  • The only difference between the two hubs is the inside dimension of the grease seal included with the hub drum. The # 42866UC3-EZ uses a 10-36 grease seal with a 2.25 inch inside diameter and the # 8-219-4UC3-EZ uses a 10-10 grease seal that has a 2.125 inside diameter. To determine which is compatible with your existing spindle, you will need to use a digital or dial caliper to measure the surface of the spindle that the grease seal rides against (see diagram). If this surface of your...

  • Does Redline Trailer Bearing Grease Seal # 29031 Include a Spring
  • The Redline Trailer Bearing Grease Seal # 29031 that you referenced does not include a spring. This single-lip seal is for use in the inside end of a trailer hub (the side closest to the axle and furthest from the spindle). I think the part with a spring that you are referring to is a special type of outer grease cap (not an inner grease seal) called a Bearing Buddy. These mount on the outside end of the trailer hub/spindle in place of a standard closed grease cap. They hold a supply...

  • Comparing etrailer and Dexter 3,500LB Self Adjusting Brake Kits For a AL-KO 3,500LB Trailer Axle
  • I feel our etrailer Brake Kit # AKEBRK-35-SA is a great option and many have commented on how well they stand up to the test of time. With the much lower price of our brakes over the Dexter # 23-468-469 it also allows you to just replace the complete assemblies rather than just replacing pads, springs or magnets to make the Dexter more affordable in the future as all the parts will wear out on either system. The Bearing Kit # BK2-100 is the correct kit for AL-KO 3,500lb axle utilizing...

  • Replacing Axles Or Replacing Brakes/Bearings On 2006 NuWa Discover America 5th Wheel Trailer
  • I would be happy to go over the replacement brake/bearing and replacement axle option for your 2006 NuWa Discover America 5th Wheel Trailer. Unless your axles are currently damaged, or for some reason use an obsolete bearing combination I would stick with just replacing the brakes and bearings as that will be much more cost effective. To determine which brakes and bearings your axles use we will need to find the axle rating of your axles, and the bearing combination of your spindles. The...
