Trailer Hub/Bearing Question
I was given an old 1982 Dilly bunk trailer that has not been used in years. The frame of the trailer us in great shape, without any rust. It spent most of its early life in a garage. I'd like to use it again to carry my 14' Jon Boat. So I've decided to replace the Springs (they looked rusty) and the Bearings. When I took the hubs apart I found a lot of rusty colored goop inside. Obviously condensation and the rain water got in there, It had a hard time getting the hubs off because the inside bearings were stuck on the spindles. Not wanting to damage the spindles, I took out my grinder and I made a groove in the stuck bearing sleeve. Then I was able to cause a tiny crack and they slide right off, The spindles look pitted but seem fairly smooth, The outside of the hubs is a little rusty too and the inside of the hubs (where the bearings would ride) looks a little pitted too, but seems smooth to the touch.
How do I know if the spindles and hub are too pitted and need replacing? I can replace the hubs easy enough, but the axle is an odd size. The axle, has a little rust, but not bad except for the pitted spindles it looks okay. Its a galvanized square 1.5" axle, its 55-1/2" tip to tip, has 1" spindles and spring center distance is 39-1/2". I can't seem to find another axle just like it. Yes....this is my first trailer.
