I just had my 30,000 mile service done....cost $290 from Fred Martin Isuzu. They did all the checks, plus changed the tranny fluid, front and rear diffs, flushed the coolant system, and repacked the front bearings. I had already changed the oil and TOD fluid, plus supplied the Royal purple synthetic fluids. The only thing they didnt do was change the power steering fluid (they questioned that as did I) and the auto tranny fluid change only took 3.5-4 qts???
