I linked our main page for trailer grease seals which has filters that allow you to select parts based on dimensions and other features, such as single-lip or double-lip types.

We do not offer any seals with your exact inner and outer dimensions. If you can, re-check those dimensions using a precision digital caliper like # PTW80157. It is best to measure the spindle and the hub bore rather than the original seal part since the seal can become distorted with age and wear.

The seal with the inner and outer diameters nearest to your measurements is # SL150 which has an I.D. of 1.500 and an O.D. of 2.332-inches.
