Fluids

[Shooter04]

Brought my truck home for the first time last year used with 94k miles on it. Here I am a year later with 107k miles on it and so far the only fluids I've changed is the engine oil. I have absolutely no records of what the three previous owners did before me so my question is....

What fluids should i change? ie Tranny, transfer case, brake lines, etc. Also what are the fluid change intervals for my truck?


Thanks guys!

Change all of it- transmission and filter (flush it if real dirty), transfer case, front and rear differentials. wouldn't hurt to bleed your brakes to get new fluid through the lines, some would even say to flush your power steering fluid. Wouldn't hurt to change the antifreeze either. You should be able to find maintenance intervals in 1) your manual, 2) repair manual, or 3) I think there is something in the 7.3 tech info category on here. Let's see.. what am I forgetting?... I keep a handwritten record in the glove box of the maintenance I've done and at what mileage, makes it simple to figure out when you need to change fluids! BUT, the suggested intervals are just that- suggested. It will take some of your judgement too, to determine when your fluids need changing.
