I believe that I've found the problem with my X, but I really don't want to go back to Zimmerman Mitsu in Cedar Rapids. They seemed to put more effort into coming up with reasons to deny a warranty claim than actually locate the problem (which they didn't find) and then fix it. There are no Mitsu-authorized service places in Iowa City. I'm looking for suggestions within a reasonable distance. Does anyone have any experience with LuJack in Quad Cities? Are other suggestions? I'd go up to Waterloo or over to Des Moines if you all say that they'll be helpful. If it matters, it looks like I have a dying left-front inboard CV joint. Thanks.
