Hey Mike, it's good to hear from you again!

According to my research you should need the Grease Seal # TMK58ZR which has a 1.719" ID and a 2.565" OD, but you'll want to verify this on your end. From what I was finding, your 2000 Ranger Bass Boat Trailer should have a 3,500 lb axle which corresponds to the seal I referenced above.

@MikeC The Easy Grease Trailer Idler Hub Assembly for 3.5K Axles # AKIHUB-545-35-G-EZ-K should fit your trailer if you have a 3.5K axle. You'll just want to verify that you have an L68149 inner bearing, L44649 outer bearing, and a grease seal with a 1.719" inner diameter. Do you currently have idler hubs, or is your trailer equipped with brakes?

@JonG It is a single axle trailer with surge brakes

@MikeC In that case I recommend the Easy Grease Trailer Hub/Drum Assembly # AKHD-545-35-G-EZ-K instead. This uses the same bearings and seal sizes, and works with a 10" drum brake assembly.
