I've got 120K on my '03 V8 4x4, so what do I need to replace? I'm doing plugs, PCV valve, brake pads (originals but still not really needed), brake fluid, air filter (of course), did AutoRX. Should I change the plug wires? I know that they are different than what I'm used to, so just wondering. Also wondering if I should do the whole sea foam thing. I'm also debating on if I should flush the transmission. I did it at 60K I think. I also did the differentials, etc. at the same time with 90K amsoil, so may wait a couple of months for that. Timing belt, water pump, fluid, seals, thermostat done at 95K.
I don't do any serious 4 wheeling unfortunately, just lame field running while hunting and fishing. The rest of it is pretty much highway, with very little traffic driving (as my brakes can attest).
Suggestions? Any certain plugs? I was just going to use OEM.
