My new-to-me Suburban has had a rough previous life, clearly. Over fourteen years of use, I'm now noticing signs of previous repairs that weren't done right and botched maintenance. Well, I haven't found anything yet that isn't repairable, but the other issue is, I simply don't know the vehicle's maintenance history. What has, or hasn't been done? When was the transmission fluid last changed? I know the coolant has been changed (since I bought it with only water in the system) and I know the transfer case fluid has been changed (since there was no fluid in it when I bought it). It seems Diesel maintenance information, especially for an older Diesel engine is scarce online, so I had to resort to paper research to find the GM Diesel Supplement defined scheduled maintenance listing for "Long Trip" use on a Suburban. These should be considered *maximum* values, not when you start thinking about doing them.
