I have had the Camburg LT kit for over a year now and love it. I have over 50 desert trips on the truck since I purchased the kit and its time for new bushings. I haven't experienced any problems but the truck is starting to make some squeeling noises and most of the grease around the bushings looks to be gone. Not bad for over a years worth of abuse. I would really like to see some of the shop owners answer your question though. People that make the kits should reply and let the consumers of their products know what maintenance should be.
I have had my TC Caddy kit for over a year now and I have not had the arms off one time for anything lol..and thats with going to some sort of desert almost every weekend with it.
Sure it squeaks but you get used to it. An upgrade you can do so the bushings last longer and make no noise is have them all replaced with Delron. Its a bit of $$$ but it would be worth it. When I ever take my arms off I will be replacing them with Delron.
My arms are home made but use urethane upper and lowers with heims on the inners and outers. Over a year and no wear problems, I work construction and it sees dirt daily. I put aprox 40k plus miles per year, mark almost every MDR course. It sees a lot of abuse. I do ocationally remove the heims and clean and lube them. Ditto on the delrin.
speaking of turning down stuff i work at a machine shop and my friends at work have helpped me out alot. They tell me to tell anyone and everyone they will do any lathe work and mill work you would like if its not to difficult. just let that be known and im sure they wont ream you either cause they usually work on the stuff during work time so. theres the offer.\
you can get a 2 inch or whatever o.d. pole you need in whatever feet you need of delron. Then you just turn out what size you want. Pretty easy and the delron is cheap, I got 3 feet for 25 bucks. Turning them out right now. Just make sure that the sleeves are a little bit longer than the bushings so the bolt is tightened down on the sleeve and not the plastic. Tim
