What is the bearing size used on a Hobie trailer

I have a Hobie trailer (2002 Carnai SC-1175). It's time to do some preventive maintenance and I wonder what the bearing size is and also what a proper replacement hub would be.

Thanks.

When you change the bearing put "Bearing Buddies" on, they allow you to pump the bearing full of grease after you put the trailor in the water, it will push all the water out and make the new bearing last...forever. On my bass boat trailor, I keep the bearings packed in grease with the bearing buddy's and the trailor has nearly 20'000 miles on it since the last bearing change and it still sounds like new when you spin that tire.

The size of the bearing depends on the trailer. When you take the old bearing off just get on that matches.

My previous trailer had "bearing buddies" and I kept them full of grease. I was as confident as you expressed in your response but I discovered my folly when I stopped to buy gas and found daylight where I should have had bearings. "Bearing Buddies" only help you keep the hub completely full of grease reducing the amount of water that gets in. They do not replace the old grease or the water that got in.

The reason for asking the question about bearing size was to buy the parts before taking the hubs off. I may even buy hubs with a zerk fitting on the inside of the inner bearing. That way the new grease should actually pump out the old grease.

You should be able to clean up the old bearings and bring them into almost any auto parts store and get a replacement. Bearings have a part number etched into them that carry across to different manufactures. Bearing buddies are a good plan but they still have to be repacked once in a while. The spindle needs to be tightened just to take out the slop from wear. Also use synthetic grease, its not much more expensive and has much better properties under stress. Make sure to bring bring in a seal as well and replace those. Most trailers are standard sizes. 1", 1 1/4", 1 1/2" spindles etc. When tightening the spindle you want to spin the wheel while tightening. Tighten until there is a small amount of resistance, or slowing of the spinning wheel. Back it off until the castle nut lines up with the first hole in the spindle and put in the pin. Those little wheels spin like crazy so check them often.
