Tune-up Questions

[Juice75]

So I'm going to play dumb here. My '02 Yukon is at 117k, and I'm sure it's over due for some tune-up maintenance. Outside of plugs, wires, air filter and PCV, what all needs to be done? Fuel filter is new, so I can rule that one out.

Thanks!

check u-joints, hubs, change you diff and trans fluid with a good sythentic. do not flush the trans. only replace whats in the pan and put a new filter in.

Oil and filter change

Rotate the tires. Check brake pads and fluid. Top off coolant and power steering fluid. Lube joints. Don't forget to check spare tire pressure. Check belt condition. That's all I can think of.

Do the injectors need to be cleaned, or anything like that?

pouring seafoam or some type of injector cleaner into the fuel tank will take care of that, and yes that is something that needs to be done every so often
