Outer bearing is 1 1/8 axle I need a kit with bearings , races, seals I might as well do both wheels. Are these sizes standard ? Thanks

We offer both individual bearings, races, and seals as well as complete bearing kits in many common parts combinations. The best way to know what parts you need is to obtain the part numbers from the existing bearings and seals. The linked photo will show you the typical locations and appearance of these part numbers. You can directly enter the individual part numbers on our site. This method is far easier than measuring.

Measuring will requires a precision digital caliper and measurements to the nearest thousandth of an inch (3 decimal places, such a 1.378-inches). Once you have your measurements you can then use the link provided to see the bearing kits and individual parts we offer. Filters on the page allow you to narrow the results to the parts or kits suitable for your trailer based on their inner and outer diameters.

I have included links to two helpful videos that will show you the process of packing and replacing your bearings.

It is definitely a good idea to change out the bearings/races/seals in both wheels since otherwise you may soon have the repeat the process on the other side. Replacing everything will give you the peace of mind of knowing that all parts are new and have a similar lifespan.
