99 ML 320 190,000 miles

1> transmission rebuild at 185,000 miles. Cost was $2500. Could have been as much as $6500 if I had taken to dealer.

2> no rear end trouble

3> differential trouble: Dealer replaced transfer case switchover motor at 24,00 miles (warranty). I think it failed again about 50,000 miles ago but I decided to stick my head in the sand and not risk disabling the vehicle by trying to engage low range. Haven't needed low range in the supermarket parking lot yet.

4> engine trouble (head job or rebuild only): Not sure if this qualifies but I paid my indy about $500 to clean the EGR valves at 104,000 miles. Don't remember the details, but I was getting CEL and he reported sludging. No problems since.

Note: I change the oil based on the maintenance minder (usually around 15,000 miles). I didn't intend to go beyond 10,000 miles, but turned the truck over to my wife several years ago and I lost sight of the mileage. After about the third time it went well over 10,000 miles between oil changes, I decided to just change it when the computer told me to change it. The longest interval was over 19,000 miles. The dealer's service advisor chastised me that time. I told him to take a hike because they marketed the truck with that capability and I was following the owners manual.
