• How Far in a Trailer Hub Should the Grease Seal Go
  When installing a seal at the back of a hub the outer part of the seal will need to be flush with the hub. I have linked a video that should help. You could watch the whole video or fast forward to the 1 minute, 50 second mark to see the seal installation.

• How to Correctly Position Oil/Grease Seal in Trailer Hub
  An oil seal like Redline part # 9103309 installs in the back side of the hub (the side nearest the trailer's frame) with the sides or "legs" of the seal inserted into the hub's bore. This means that the flat metal surface of the seal will face the trailer frame. The linked photo of a seal will show you both sides and indicates the direction in which it should be installed into the hub. I have linked both an article and video on seals that may be helpful to you.

• Can The AKIHUB-865-7-2-EZ-K Hubs Be Converted From Grease To Oil Bath?
  Hello Terry, thanks for reaching out. Technically, yes, the # AKIHUB-865-7-2-EZ-K hub could be converted over to an oil bath hub. The thing is, this hub comes pre-greased. So you would have to remove the bearings and clean every speck of grease off of everything in order to change over to oil. This would be super messy and time consuming. De-greasing a bearing is not fun. A better option will be to go with the # AKIHUB-865-7-1-EZ-K hub assembly instead, since it does not come pre-greased....

• Will Kodiak 8k Disc Brakes for AL-KO Axle Fit etrailer Axle
  Hey Don! The Kodiak # KOD32FR will not fit the etrailer # e35GR. These brakes are designed to fit a 4-bolt brake flange on 8k axles and the etrailer 7k axle has a 5-bolt brake flange. Even if they matched, these are specifically designed for the old AL-KO axles which are a little different. For 7k disc brakes with 5/8" studs I recommend the Kodiak Disc Brakes # KOD63FR instead. Are you wanting oil bath disc brakes? These are designed for grease but can be converted to oil bath by swapping...

• How To Determine Which Replacement Bearings and Grease Seal Are Correct For Boat Trailer
  There are two different ways to determine which replacement bearings and grease seals will fit your boat trailer. The first is removing the hub and looking for the bearing numbers stamped on the face of the bearing as shown in the included picture of the # L44649, and looking for any part numbers stamped on the face of grease seal. If your bearings/grease seal is worn to the point that you cannot read the numbers then you will need to use digital calipers # PTW80157 to precisely measure...

• Is There An Issue With Seating Grease Seal Slightly Below Hub Face?
  There is not an issue with installing the grease seal # 9103309 you were looking at 1/16" below the face of the hub. It will still seal against the grease seal surface on your axle, though you will want to make sure to not force the seal down to far as you can press it down against the bearing and race and cause issues there. I included a video showing the grease seal, inner bearing and race, and outer bearing and race being installed on on a hub for you to take a look at.

• How to Identify Correct Replacement Grease Seals and How to Install Them
  The best and easiest way to identify a replacement grease seal (or bearing for that matter) is by the original part's reference number. The linked photo shows the typical appearance and location of these part numbers on seal, bearings, races. It also shows where to measure your spindle if the part number is not available. Note that measuring spindles requires a precision digital caliper to measure to the nearest thousandth of an inch. I have linked you to an article and a video on the...

• Removal and Installation of a Unitized Oil Seal for a Trailer Oil Bath Hub
  Unitized oil seals such as # 10-63 for example are different than regular grease seals. Unitized seals have an inner part that stays fixed to the spindle on the axle and its outer case rotates with the trailer hub. You would remove and reinstall a new one the same way you would with a regular seal. The best tool to use for unitized seals is a seal removal tool which you should be able to get at a local auto parts store. Once you pry out the old seal, place the new one in the hub. Use a...

• Proper Direction To Install A Hub Seal On Trailer
  When replacing a grease seal, the metal part of the seal will face towards the inside of the trailer and the rubber part of the seal will face toward the back side of the wheel. The air side of the seal is the flat side of the seal and faces out when it is installed in the hub. The item you selected, Oil Seal, part # 9103309, is designed to be used with hubs that use gear lube instead of grease. If you can send me the inner and outer bearing numbers that are stamped on the bearings, and...

• How do you Install a Grease Seal After Replacing Bearings or Re-Packing Grease
  The seals should be replaced each time you re-pack the bearings. When you take the hub or drum apart, toss the old seal and use a fresh one when you reassemble and pack with new grease. It install the new seal, gently tap it in a hammer, evenly working around the seal. We have a really good video on removing, disassembling, greasing and re-assembling a drum that will be very helpful. The seal install portion can be found at the 10:50 mark.

• How do I replace the oil seal on my trailer?
  First, to remove the seal, turn the hub over with the wheel studs facing up on a hollow cinder block or on a couple of 2x4s. You will need to remove the seal by using a 1" wood dowel rod or scrap lumber that will fit into the center of the hub. Place the dowel rod against the inner bearing and knock out the bearing with a mallet in a circular motion. The wood will force the seal out without nicking the bearing or race. Be careful not to damage the hub and race when prying it out. The best...

• Unitized Oil Seal for Trailer Hubs Installation
  The item you selected, while having the right measurements, is not a unitized oil seal. We do carry the 10-63 unitized oil seal (see link). Installing the seal requires pressing the seal flush or slightly into the hub. I normally use a wooden block to seat the seal flush with the back side of the hub. We have an install video for you to watch that shows installation of a grease seal. Normally flush installation is correct unless Tie Down Engineering specifies differently.

• How to Find the Correct Replacement Oil Seal and Oil Cap
  I have a solution for you, but it looks like the oil cap itself is what is cracked and not the oil seal. I recommend taking the cap off and making sure that it's actually the seal and not the cap that is cracked before proceeding any further. Once you determine which part is actually damaged, you'll need to take some measurements on the inner and outer diameter (oil seals) or just the outer diameter (oil caps) to determine which replacement part you need. An oil seal like the Redline...

• Choosing Between Oil and Grease Seals for Dexter 5.2K Axle
  The seals # 9103309 and # GS-2250DL have the same inner and outer diameters (2.250" ID and 3.376" OD) but they are used for different applications. Use the seal # 9103309 if you have an oil bath setup but you'll want to use the seal # GS-2250DL if your hubs use grease. The seal is a little different for either application which is why they are specific. These do line up with what you find for a typical 5.2K axle.

• Recommended Oil Seal for Damaged Trailer Stub Axle
  For your 412920 seal replacement, I recommend the Oil Seal # 9103309. This is the strongest seal we offer as a replacement for your EZ Lube axles. They are a tight seal intended for oil use but will also work with grease and be a stronger seal than a typical grease seal. If these seals doesn't work, then I recommend replacing your spindles.
