Suspect a worn left side spider gear or it's bearing in the differential. If a limited-slip differential, the left side clutch may be grabbing somewhat. In any case, the differential will need to be removed from the case to service any worn or defective components. Rear end service is not for inexperienced mechanics. Have you checked the fluid level in the differential? Hope this helps!

I had a chevy 2002 avalanche,2004 chevy tahoe both after 20,000 miles developed a mild lifter or slight bearing knock.When I confronted chevy with this problem they stated this was normal for the 5.3 liter v8.Being a mechanic myself didnt think this sounded right.My friend has a 2003 gmc yukon and motor sounded same way.I no longer own my chevy,But my friend still has yukon with 150,000 plus miles and yet it still knocks when you start it.this is just a problem with chevys and other gm products.

Did you put at least 3 gallons in?

check fuses

Reduced power is a mode the engine goes into when there is something wrong with the cooling or the firing. If the engine gets to hot it uses the pistons to air cool. This of course is not a for sure but where I would start.

Still try a new fuse in it because it still could be faulty.

reset the CPU program after the battery change out. Use a code reader for this process as the program is corrupted

seems like your alternator might be the problem. http://www.ehow.com/how_5730586_replace-chevrolet-avalanche-alternator.html

check fluid level and condition (burnt smell or not red color) checkfor transmission codes sounds like internal issue

If it's a diesel, the electric fuel shut off solenoid on the pump is stuck or not working, replace the solenoid. Hope that helps
