How to Measure Trailer Spindle & Hub to Determine Grease Seal Dimensions
Question:
Hi there. Quick question, I have a 1-1/6inch spindle using L44649 and L44610 Bearing Set. What size of grease seal do I need. I cant see any part # on my old ones. Thank you for your help.

Expert Reply:
Since we do not offer any hubs that take the bearing set L44649 and L44610 the best way to determine which grease seal you need for your spindle is to measure it to three decimal places (like 1.234-inches) with a precision caliper like # PTW80157.
Please refer to the linked photo that shows where to measure your spindles for the seal's inner diameter (position B). You will also need to measure the hub's bore where the seal will be installed; this will tell you the outer diameter for the seal.
Once you have these dimensions you can use the page linked to select a grease seal with matching dimensions.
