I bought a nifty trailer off craigslist last summer. It's about 4'x6' with heavy construction... the kind that 4x4 enthusiasts build to tow behind their Jeeps. We drug it about 1000 miles around eastern oregon this summer, and I had some problems. The trailer was built from scratch, and the axle was made from a piece of heavy wall pipe. The builder attached hubs from a Jeep, one side has some of the parts to rebuild a locking hub. The trailer was designed so that both tires and the spare would fit a Jeep, too, all the tires would be the same size. But I was worried about the bearings, so I popped the grease cups before the trip, pulled everything all apart, and repacked the bearings. I couldn't put my finger on it, but something didn't seem right... I don't know if parts were missing or, if it was just a different system than I was used to, but I had a feeling I would have problems. Well, down by three forks in Rome, I noticed the tires were wearing unevenly. I wiggled the tires and they rocked back and forth, about an inch of play. I popped the grease cups and tightened everything up, and that lasted until we headed north. When we crossed over into Idaho, I stopped and checked the tires, and one was worn so bad I decided to change it before it went flat. When I changed the tire, the wheel bearings were loose but not ruined, so I buttoned everything back up, reset the locknuts, and made it home without a flat. The wheel bearings are loose again, and I think there was some flaw in the building process. I am towing this trailer behind a 4runner, and although we are off road a lot, we're not doing any rock-crawling. I like the idea of building another axle with 4runner hubs, but really, I just want a serviceable axle with a tried and true sytem that will run problem free. As long as the wheel pattern matches up, I'm happy. So my question is, should I find a shop that can fab an axle? Any idea what that would cost? The problem is that the cost of that could eclipse the value of the whole trailer... I guess I could also try to find one that would fit from an outfit like Grainger, too. Any advice? Anybody on here wanna fab one? thanks!
