"Begone demons ... begone."
If you do house calls my wife's Blazer (the "Anti-Christ") could sure use a treatment.
Now that is funny. My truck was exhibiting some of those characteristics as well. Doing pretty damn good now though after rebuilding:
1. Transmission at 111,000 miles
2. Front differential at 120,000 miles
3. Rebuilt rear end and new G80 locker
4. New transfercase around Christmas time (SOB) @ 139,000 miles.
5. Power steering unit around the same time.
The damn 5.3 still runs like a champ though. For some reason it doesn't use a drop of oil between oil changes and it runs like a mo-fo. I have to be easy on the gas pedal or it breaks them loose. I can't say enough good about that damn LS1 engine. Great design. However, to own a chevy/GMC you need to be a little mechanically inclined... Hint..
