  • How Can I Identify an Axle Without a Sticker?
    Thank you for the pictures! It looks like you've got some sort of square drop axle on your trailer and if you can't find an identifying sticker, I can still help you figure out what you've got so that you can make the swap to electric brakes on your trailer. It looks like you've got 6 bolts on the wheels, which can help narrow down our search, but we'll need to know what size the brakes on the trailer are and if possible, what size (or number) the inner and outer bearings are on the hubs. If...

  • Looking For Replacement Seals For A 40 Year Old Triple Axle Trailer
    Hello Robert, sorry to hear the seals you got did not work. Being that this trailer is so old, I am not surprised to hear that finding replacement parts has been difficult. Looking thru all of the seals we carry, I do not find an exact match, but we have one seal that is quite close. The closest thing that I see is the Grease Seal # 10-40. This has an ID of 1.938" which should be perfect. The OD of this seal is 2.510" though, so it is a hair larger than what you measured. Since we don't...

  • Is There a Replacement Seal for 10-40 with Double Lip?
    For your 8-248 hub with # 10-40 grease seal, the 10-19 double lip # RG06-050 is not compatible. We don't have a double lip seal that will be compatible in size. I recommend you stick with the single lip seal # 10-40 as a replacement.

  • Upgrading Axles On Equipment Trailer To Standard Spindles To Replace Dexter 8-222 Drums
    I have an option but the Dexter 8-222 drums you have on your trailer are primarily used on mobile homes and the only parts we have available for them are the inner bearing # L68149, outer bearing # LM67048, and grease seal # 10-40. My recommendation is to replace the axles which will give you standard spindles and make finding replacement parts now and in the future easier. To know which axle, you will need you will need to measure your current axle's hub face to hub face and spring...

  • Solution for Replacing Dexter 8-222 Trailer Hubs and Bearings
    The Dexter 8-222 model hubs currently on your trailer are designed primarily for mobile home use, and these types of hubs typically use unique bearing combinations that make it really difficult to find full replacement assemblies. Mobile home parts like these are really only manufactured for one time use so replacements aren't usually available. The only replacement parts I can offer for your existing setup are the bearings and seal, which can be found with part # L68149 for the inner...

  • Replacement Bearings for Dexter 8-222 Hub
    I looked up your Dexter 8-222 Hub and was able to find the inner and outer bearing numbers as well as the grease seal used. It looks like this particular hub was designed for mobile homes and these, for the most part, have more unique bearings and bolt patterns because they are technically manufactured for one time use only and not meant to be altered or replaced. Because of this, there is unfortunately not a 6 on 5-1/2 inch hub available that will be compatible with your trailer's axle...

  • Availability of Replacement Grease Seal with 1.938 Inner Diameter and 2.523 Outer Diameter
    The closest grease seal we have available to the dimensions you provided is the Redline # 10-40. This seal features the same 1.938 inner diameter but a slightly smaller 2.510 outer diameter. This may work as a replacement on your hubs but we do not currently have the 10-41 grease seal available.

  • Difference Between Trailer Hub Grease Seals 10-40 and 10-19
    The part # 10-40 is a single lip grease seal with a 1.938" inner and 2.510" outer diameter. The part 10-19 # RG06-050 is a double lip grease seal with a 1.719" inner and 2.565" outer diameter. They are not the same and will not work in place of one another.

  • Replacement for Dexter Mobile Home Axle Grease Seal 10-41
    Dexter part 10-41 is a grease seal for a mobile home utility hub. It has a specified inside diameter of 1.938-inches and an outside diameter of 2.523-inches. The nearest match we offer is the Redline part # 10-40 which is a single-lip seal that has this exact inside diameter and an outside diameter of 2.510-inches.

  • Upgrading Dexter 8-222 Trailer Hubs
    The Dexter 8-222 was used on a mobile home axle, according to my research. Mobile home axles are meant for a one time use, so there aren't compatible replacement hubs available. If you need replacement bearings and seals, you will use # L68149 for the inner and # LM67048 for the outer. For the Grease Seal you will need # 10-40. If you can provide the hub face to hub face and spring center to spring center distance, we might have an off the shelf replacement axle that uses common bearing...

  • Is a 10-40 and 10-19 Grease Seal Interchangeable
    The part # 10-40 is a single lip grease seal with a 1.938" inner and 2.510" outer diameter. The part # RG06-050 is a double lip grease seal with a 1.719" inner and 2.565" outer diameter. They are not the same and will not work in place of one another regardless of whether or not you have EZ lube spindles. In order to determine the correct size grease seal your trailer uses you would need to pull off the hubs and measure the grease seal seat on the spindle with a digital caliper like part...

  • Dexter Hub 8-248 Bearing and Seal Replacement Recomendations
    I am surprised you have a # 10-40 hub seal. The Trailer Hub and Drum Assembly # 8-247-50UC3 that you said you have would take a part # 58846 seal or # RG06-020. And then for bearing part # L68149 for the inner bearing, part # L44649 as outer bearing. For races part # L68111 for inner, and # L44610 for outer. If you do have different bearings than what I listed you don't have to order the bearings all as a kit. You could piece together all the parts you need by ordering them individually.

  • Replacement Parts for 18k Triple Axle Trailer
    Hi Jeff; assuming 3tubes meant 3" axle tubes/axle diameter you can use the Demco Trailer Brake Mounting Flange # DM52415 for 3" axles. However, if those bearing measurements are correct it indicates you have a # LM48548 inner bearing. We don't carry any hubs that use this bearing. I will also need to know the axle capacity to find the right brake assemblies. The closest thing we have for a hub and drum is the # 8-407-5UC3-EZ which uses the # L68149 outer bearing with a 1.378" inner diameter...

  • Correct Replacement for Dexter Grease Seal 010-004-00
    The Redline Grease Seal part # 10-40 is what you need to replace a Dexter Grease Seal 010-004-00, they are the same dimensions. The only difference is that this new seal is a double lip and the one you have is a single, double has better protection than single so it's an upgrade.

  • Looking for Grease Seal with 1.87 ID and 2.5 Inch OD for MHU Axle
    The difference between the ID of the seal and the diameter of the seal riding surface on your spindle, although a VERY small amount, is large enough so the seal will not be compatible. This assumes that the 1.87 inch diameter of the spindle you had was measured with a digital caliper. MHU (Mobile Home Utility) axles are typically not DOT approved and are only meant for one-time use. Many enterprising folks used these axles to make trailers, which usually works pretty well until the time...

  • Bearings for a Dexter Trailer Hub 8-222
    I called Dexter Axle and they were able to inform me that your Dexter Trailer Hub 8-222 uses a part # L68149 inner bearing, part # L68111 inner race, part # LM67048 outer bearing, part # LM67010 outer race, and a part # 10-40 grease seal. Unfortunately, we don't have a bearing kit with all of these parts for you so they will need to be purchased separately.

  • Is There a Double Lip Seal To Replace the Dexter 10-40 Single Lip Seal?
    Unfortunately Gary, the Grease Seal # 10-40 is the only seal we have in this size. It is a single lip seal with the metal outer portion and rubber inner section.

  • Can Dexter 8-222 Hub be Replaced with 6 on 5-1/2 Inch Hub on Tandem 4 Ton Trailer
    I did some research on your Dexter 8-222 Hub and was able to find the inner and outer bearing numbers as well as the grease seal used. It looks like this particular hub was designed for mobile homes and these, for the most part, have more unique bearings and bolt patterns because they are technically manufactured for one time use only and not meant to be altered or replaced. Because of this, there is unfortunately not a 6 on 5-1/2 inch hub available that will be compatible with your trailer's...

  • Grease Seal 3504 Replacement Availability
    The closest seal we have to the dimensions you listed is the part # 10-40. This seal has an inner diameter of 1.938 inch and an outer diameter of 2.510. If you remeasure the seal you might find out that this seal would work, but if the numbers you listed are exact then this would be close, but not close enough. For the inner diameter it might be better to measure the outer diameter of the spindle the seal rides on.
