The Durango will have 100,000 miles in a few months and want to know what kind of maintance i need to do? I do not have a manual and i have replaced the spark plugs,throttle postion sensor and the crank sensor. Should i change the trans fluid and have the filter cleaned? It is a 2001 4 wheel with a 4.7. The belt looks good. What about the timing chains and the fuel filter? thanks

 

the 100k maintance items are the trans fluid/filter (replace only do not flush) and the serpentine belt iirc, as stated check your owners manual, if you belt still looks good grab a new one and throw the old one in the back, if the one lets go on the road you have so met hing to stick on it on the side of the road

 

I don't have a owners manual

 

I do have an '01 FSM, and the only item shown specifically at 100k is trans fluid/filter. Everything else in the 100k'ish area is normal 30k interval stuff and oil changes.
