How many miles can a Tahoe be good for
With proper maintenance 200,000-250,000 miles. After that, major parts need to be overhauled and it's better to get a newer truck.
MANY MILES, slap a new motor and tranny in her and run her to half a million.
I have 194k on mine. Original motor and trans, I've put alot of work in it, but the body is in great shape. You'll start to "feel the road at around 130K even with new shock, body mount go to shit around this mileage. The good thing is that motor's are cheap and not bad to replace.
I have a 2002 Chevy Tahoe with original motor and trans... over the life of it I have change fule pump, battery, alternator and water pump... Me and ole girl are now at 305,763!
I have seen an Avalanche, which is the same basic vehicle, with over 425.000 miles. Transmission replaced at 398,000 miles, but the engine is still going. I have over 202,000 miles on mine with the original front brake pads which were around 50% last time I checked. There are some smaller parts that tend to fail that I have had to replace, the knock sensors, intake manifold gaskets, water pump, rear load leveling shock air pump, and a fuel pump, and the windshield washer pumps. There are a few other items that need work, but nothing unusual for any vehicle. The mentioned repairs are all normal issues, and except for the air and fuel pump, pretty straight forward and reasonably priced repairs. I hope to drive mine for a very long time. I have been able to do most of the repairs myself and there is a lot of information out there to help with most of the repairs.
