I'm sure this question has been asked many times, but being a newbie I will be the one to ask it again; Are there any detailed procedures on how to perform routine maintanence (clean and lube) on a coleman lift system for our 2002 Utah? I've looked through the manual and the lift system repair manual but it literally just says lubricate! Where do I lubricate and with what lubricant? I had an incident after towing where the roof wouldn't stay up, so I cranked it up until the clutch re-engaged and it worked, but the system sounded very rough and squeeky. So I figured it's time for a lubrication before something breaks, especially before my next trip in a week. 1. The Wiffle tree seams simple, remove the cover, and lube, but with what lubricant? 2. I understand the the pulleys get a small amount of silicone lube, but where are these pulleys located? are some in the lift tubes? 3. The chain & crank system. Again how do I get at it, and what do I use? 4. Am I missing anything else to maintain? Thanks!
