Use the Cross Reference to Match the Seal You Have

Seal numbers are not always listed the same way across axle and hub brands, so the cross-reference data gives you another way to confirm the replacement before the hub comes apart. This unitized oil seal matches the following common seal numbers:


Brand Part Number
Chicago Rawhide/SKF 46305
Dexter 010-055-04, 010-055-01, 7700079

How to Measure for a Replacement Seal


Measuring a spindle

Use a digital caliper and measure to the nearest thousandth of an inch.

  • Seal I.D.: Measure the diameter of the spindle at the grease seal seat (B), where the seal rides.
  • Seal O.D.: Remove the old seal and measure the inside diameter of the hub bore where the seal presses into the hub.

Measure each location in a few spots to check for wear or an out-of-round surface. Match both measurements to the replacement seal.

Yes, these items are still performing as expected no issues what so ever.Thanks for checking in.

by:
Bought new axel parts and brakes bigger wheels for my boat trailer. My existing axel was 20 years old and never was adequate for the weight it hauled causing wheel bearings to wear out and the chance of loosing a wheel. This was the most economical way to repair as a new trailer was so expensive. All the parts I needed were available and went together beautifully. Very happy with etrailer, this is not the first time I have ordered from them great option for any parts you need.
by:
Very good seal. The only time we've had to replace them is when a bearing was overloaded and overheated the hub, resulting in overpressurization and seal blowout. Otherwise, I've got a 26K trailer running 6 of these over the past 10K miles with no issues.
by:
Great place to purchase parts from. Great parts descriptions, Easy ordering, quick shipping, and the parts are correct!
by:
Working fine after one year.
by:
I have received several different orders from trailer in the last couple weeks. Everything from a B&W fifth wheel hitch to trailer brake assemblies and lastly, axle seals. Everything received was very professional with excellent helpful service when help was requested. The seals that I just bought were exactly half price from what they would cost from a local vendor. Outstanding products as well as service!!!
by:
prompt service excellent customer support
by:
I haven't has a chance to install them yet, but looking at the product it appears to be high quality. The customer service was excellent. My only complaint was the shipping time and costs, also product had a delay in transit. This caused me to not be able to work on the trailer as planned. Over all great to deal with company... Thanks for the help.
by:
Unitized seals are the only way to go. The sealing surfaces do not move once installed. Technically they are a 2 piece seal, it rotates on itself. Worked great for 10K axles. Don't know make of axles, but they had pre 1989 Warner electric brakes on them
by:
I had to buy all new assemblies for my 40 foot trailer. the items were not only less expensive than anywhere else, but my mechanic was able to install them in one day.
I have not had any issues with them. I will buy products from etrailer from now on
by:
this is a good seal easier to install than OE seal. this seals rubber outside ring does not hold up with the higher heat of Disk brakes the rubber is melting smoth then it slips and the oil runs out.
by:
Usually you are completely on top of your game. This time my company is slightly disappointed in the timeframe of events. We stock checked all parts prior to ordering but then found out after the order was placed some were not in stock. Nobody reached out to let us know the parts were out of stock or asked if we would like to have the rest of the order shipped while waiting for the remaining out of stock items. Once we called we were able to get things moving however the shipment still was not expedited and took an additional extra five days. The products are always as expected. No issue with the quality of the parts
by:
Great seals, used for a grease to oil-bath hub conversion. 5,000 miles and not a hint of any leaks.
by:
I’m very happy with everything I purchased from etrailer. Everything was correct and fit perfectly. I’m very impressed with the service and their professionalism and knowledge of what they sell. I will definitely be ordering from them again.
by:
Purchased oil seal- 9103309 for a spare part for my fifth wheel. Great Customer Service....
by:
Exact replacement for my Four Winns boat trailer.
by:
These seals are a little more expensive but do a good job of keeping grease in the bearings and out of the brakes.
by:

Seems to be holding up, No problems as yet with this product. Thanks for the help with ordering and shipping.

by:
My parts were laying on my carport when I got back from feeding cows it looked like a train wreck. The boxes were torn apart an parts were scattered on the floor. The studs on the hubs were damaged an one of the bleeder valves on one caliper was snapped off in the housing. I was in shock an spent the rest of the day trying to fix them. I don’t no who abused my parts an tore all this up but I would like very much to beat the socks off them. That stuff cost me 2100 an some change. An I just got a bunch of junk that I’m trying to fix. The boxes were not not good enough to handle the weight. I wish I had got this from pa. Instead of etrailer.
