Well this is not exactly a Jeep trailer, but rather any type of trailer enclosed, travel, flatbed. I am curious as to any thoughts about how often to check before servicing, and replacing of bearings. I just picked up a 2003 20 foot enclosed trailer that still had it's original tires on it. So I drove over the Cascades to bring it home about 130 miles. When I jacked up the trailer at home all the tires had a bit of play, it seemed very easy to rock each tire back and forth. My guess is it had under 10K miles on it because I have a flat bed trailer bought new in 2002 that had about 10K miles, tires still had thread but I replaced the tires this summer. So if the bearings look good would I just clean and repack with a new grease seal or just install new bearings?
