Fortunately, they are working with me on it, and are OK with me checking and lubricating. The next question is what should I use to lubricate the cable. Seems like I've found articles advising against every lubricant known to man. The LBS isn't all that local, so I need to pick something up at a hardware store. Any suggestions would be appreciated.
