There is one more area which 99% of people miss and can damage not only engine, but transmission, drive-line and input shafts as well. It's as simple as that crankshaft damper bolted to front of engine which all fan belts originate. While 520,000 miles is relatively a young engine, fact is these dampers must be replaced every 500,000 miles. These dampers do and will fail and resemble a wheel or driveshaft out of balance. These are fairly easy to replace but something which must be on your maintenance radar. You will not know when they fail, but if you simply have them replaced every 500,000 miles you'll never have to find out when they quit working but when they do fail, they can cause many thousands of dollars in damage to engine and drive train. They only cost $500 - $700 dollars and are worth the investment for long running trouble free operation. A failed damper will snap a crankshaft, and can snap a drive line input shaft. It mimics a bad u-joint and you will feel it in the seat bottom. Just something I want all mechanics and owner-operators to think about.

They are actually a two piece unit with a dampening material in between that hardens and loses effectiveness and requires replacement.
Detroit says to replace at 500,000 miles or during engine in-frame.
