How to Pick Out the Correct Replacement Seal for a Trailer Hub

Question:

I am looking for a replacement grease seal. The seal has a number on it TCM 174253 TB. The inner bearing is L68149 and outer is L44649. I think I need the 10-19 seal can you confirm. Thank you,

The grease seal number you referenced doesn't cross reference with anything we offer but based on the bearing numbers you listed you would need the # RG06-050. To verify this you would want to measure the inner and outer diameter of the current seal you have. If the inner diameter is 1.719 inches and the outer diameter is 2.565 the # RG06-050 would be the correct seal. You will need a digital or dial caliper for this measurement.

Or if it is damaged you will need to measure where the seal rides on the spindle and the inner diameter of the hub where the seal is, see picture.
