I'm getting the camper cleanup and ready for the summer and while doing that I have started looking at some of the maintenance items I may need to address. Mainly the tire, brakes, and bearings. So I have a few questions here.
The tires are Goodyear Endurance with date codes of 1917 and 2017 putting them right at 4 years. They have had probably 7000 miles on them. Is it time to replace now, or wait until fall/next spring? I hear tires should be replaced by age alone at 3 years by some, and others say 5 or more.
The bearings were last done at the dealership about 2 years ago when I took it in for other maintenance. I want to service them again, but I plan on doing myself. As I have never done this for a trailer, any tips, advice, warnings? Is this something a person with average mechanical abilities could do, or for camper is this a "one small minor easy to make mistake by a novice will cause catastrophic failure" type job. Also should I make plan to go ahead buy the bearings and replace them if needed, or just plan to lube them and buy bearings if they need to be replaced. Is it normal to replace them every few years, or do they typical last along time when lubricated?
The brakes may have adjusted when the bearing were done, but I don't remember. On the last trip I noticed the trailer was breaking as well as expected, so I turned up the brake controller a little. This caused the brakes to lock up when applying them at low speeds like stop and roll traffic, or campground maneuvering. Once again I plan on doing this myself. From what I seen it seems a simple process to adjust the brakes: jack it up, adjust the brakes till there is resistance on the tire, back off the adjustment till the tire roll freely. Once again any tips, advice, warnings? and is this a "one small minor easy to make mistake by a novice will cause catastrophic failure" type job that should only be done by an experienced and trained professional. Like with bearings, should I just plan on replacing the brakes. If replacing them are the self adjusting brakes worth it?
oh, and expect the usual stuck part, scrapped knuckles, non-family friendly words, and penetrating fluid.
