Life is settling down and it is time to get some maintenance done. Trans and rear fluids have been replaced last 25k. Plugs done last 12k. I know I need to replace front diff and transfer fluid, brake and radiator fluid. What else should I look at doing? What about timing chain or other main components? I plan on driving this truck for a long time And I want it to last. The maintenance schedule doesn't exactly go up to the miles I have to follow.
