How To measure a Spindle to Determine the Correct Grease Seal
Question:
I have a 1997 Coleman Fleetwood Bayport popup camper with the following electric brake components... L44649 outer bearing, L44649 inner bearing, grease seal 13194TB, and stamped on the hub was 8-257. I am replacing the entire electric brakes assembly. My first question is if the grease seal 10-9 provided with the purchase of the 8-257-5UC3 hub/drum assembly will work on my axle. I noticed the difference in dimensions between the two grease seals. The original grease seal 13194 has an inner dimension of 1.372 and outer dimension of 1.983. The grease seal purchased with the e-trailer.coms hub/drum assembly has an inner dimension of 1.5 and outer dimension of 1.986. Am I to purchase the 13194 grease seal and use it instead of the 10-9 grease seal provided with the hub/drum assembly?

Helpful Expert Reply:
It is possible that the wrong grease seal was on the spindle/hub. The seal associated with hubs that take inner and outer bearing L44649 is the 10-9 seal. To determine which is correct you will need to measure the spindle where the seal goes.
The measurement needs to be as accurate as possible so you will need to use dial or digital calipers. I included a picture that shows where to measure on the spindle. Measuring the actual inner diameter of the seal is difficult because its rubber and can flex which would provide an inaccurate measurement.
