Replacement for NOK AD7128R Trailer Hub Seal  


I am trying to pack my trailer wheel bearings. I believe the seal for the inner bearing is NOK AD7128R. Where can I find a replacement seal?


Expert Reply:

In order to find the correct replacement grease/oil seal for a trailer hub you have a few options. The first would be to use a digital caliper and measure the spindle where the seal rides along with the hub. The second would be to measure the existing seal you have now. Please note, these measurements will need to be taken to the nearest thousandth of an inch. I have then attached a list of options below.

Unfortunately, I am not able to cross-reference the part number of "AD7128R". I have attached a help article on how to measure below.
