Bumping this thread because I need to replace my rear upper control arms as well and have the same question. Dealer wanted to sell me the value line kit, which I think they said was close to $400. Febi parts are $53.75 each from Pelican. There is also Lemfoerder which is about $100 a piece. I would pay that extra price for that if the quality is worth it, but I have to wonder how much of a difference there is. So, anyone still running Febi RUCAs? How have they held up?

Also, someone mentioned a DIY for replacement earlier in this thread, did that ever get done? Are there any good ones elsewhere? For some reason I'm having the hardest time finding service info online.
