I had a bearing go out of my tandem axle trailer a couple of months ago. It was the rear axle, with the brake, on the driver's side. Bearings were completely gone. Happened on a weekend, naturally, and my son helped me put new bearings in on Sunday, so I'd be ready to roll on Monday. We were able to get the right sized bearings at the local O'Reilly store, but not the right seal. We found one that worked, but had to be installed backwards in order to get the hub installed correctly. We were not able to remove the races from the hub, but they did not seem to be scored. The spindle showed some damage, on the lower side, but was worn only a few hundreths of an inch, at most. After installation, the wheels seem to "**** out" slightly at the bottom. I had noticed this before the bearings went, and contributed it to crowned roads and uneven tire wear, but now think it is from wear on the spindle and/or bearings. I've noticed this on other trailers as well. I used the trailer several weeks, and checked frequently to see if the hub was heating up any, which it did not. My question is, now that we are in the off season, should I consider replacing the hub and/or axle or just milk it as long as it lasts? The trailer is only a couple of seasons old, has perhaps 15,000 miles or so on it. I haven't checked, but assume a new axle and hub is not going to be cheap, but also don't want to have down time next spring. These are, I believe, 3,500 pound axles. Thanks for any input.
