Local dealer says anywhere from 100 to 200 bucks. Not bad, I suppose, but that's just rebuilding it to stock performance. I don't think stock performance is that bad but it would be nice to fix it up. I looked into rebuilding the shock myself and I am pretty good on the mechanical side but I'll still have to buy all the seals, oil, bearings, tools, etc to rebuild it. So, that should be over a 100 bucks. I just looked at Hygear Suspension, I'll keep them in mind. I just noticed Maultech is in Illinois. I wonder if they'll lower the cost to rebuild my rear shock if I throw in a YFZ rear shock. Guess I'll have to ask
