Hey Guy's, I'm getting near the 100.000 mi. mark , what needs to be done ?

 

Trans fluid and filter. Only use ATF+4 fluid and drop the pan, do not flush! I like Valvoline Fully Synthetic.

T-case fluid change. ATF+4 fluid

Differentials 80W-90 but if you want to use Fully Synthetic use 75W-90. I like Mobil LS.

Regular oil change. 10W-30 I use Mobil One Fully Synthetic.

Plugs on the 4.7L.... Plugs, Wires, and cap if you have the 5.9L-5.2L. Use cheap $2 Champion Copper plugs on all engines gap at .040

Clean the Throttle Body and IAC

Reset PCM after changes.

Clean out air pick up tubes and check vacuum hoses for cracks.

Inspect Ball Joints and Tie Rod ends for ware.

 

Also don't forget to replace your air filter if you have the paper ones! If you have a K&N drop in I'd clean it and re oil it. If you have a cold air I'd also clean it and oil it.

 

thanks...

 

I would also throw a bottle of fuel injector cleaner in the fuel. The Lucas oil "Tune-Up in a Bottle" works great.

 

My truck finally reached the 100k mark a couple weeks ago! Got a new heater core (2nd core) installed so I have a warm truck now. Bad thing is I had to rip out the carpet on the drivers side and clean up the mess the busted heater core made as you know that antifreeze does not dry up like normal water would have. Took me the entire week to simply just use a wet/dry vac and some lite cleaning soap to spray, soak, and extract a few times to get the antifreeze out of the hard foam underneath the carpet.
