Serp belt
Idler pully/tensioner
Fuel Pump
ABS Computer reflow/resolder
Front wheel bearings
Rear diff seal
MAF (stupid driver problem -- no, not this driver!)
I have over 270K on my 2001 Tahoe and the above are the only things that I've had to do to it. Diff seal went out in less than 50K, but most of the above I did not do until past 200K. Even better, all of the above issues gave me plenty of advanced warning and never left me stranded. My heater control valve hasn't failed, but I may do a preventive on it -- it was a pain when my Astro's went out. Not only did it leave me stranded (a few miles from home), but the repair required an extended hose clamp removal tool to swap out.
