To find out the correct bearing and seal size for your 2005 Trailstar Pro 185 trailer, you will need to take apart the wheel hub assembly and get the numbers off the bearings and seals. The axle capacity of your trailer would help also. Once you have those numbers, then we can get you the correct bearings and seal.

If there are no numbers on the bearings, you will need to take measurements on the spindle. I am including a link to our spindle main page. At the top of the page is a diagram showing all of the measurements we would need to find the correct bearings and seal. The measurements need to be as precise as possible so I recommend using a dial or digital caliper if you need to measure the spindle.

You can try calling the trailer manufacturer with the VIN number of your trailer to see if they will know the bearing and seal part numbers, but sometimes they still might need to know what brand axles you have on the trailer.

I am including links to videos on replacing bearings, races, and seal on a trailer hub.
