Hey James!

You're needing the Bearing Kit # TMK34ZR for your BT-151 hub. This comes with L44643 bearings and a grease seal with a 1.249" ID in case you were wanting to verify things on your end.

If your hubs are in good shape I'd keep them and just swap out the bearings.

What kind of boat do you have?
