I got a 2WD V6 with similar mileage. So far I've:
- Replaced air filter, removed HCF filter
- Replaced PCV valve
- Changed differential fluid
- Replaced sticking calipers, new rotors and pads, flushed brake fluid
- Replaced broken sway bar links
- Greased ball joints
- Replaced spark plugs
- Power steering fluid flush
- Replaced leaking valve cover gaskets
- Cleaned throttle body and MAF sensor
- A couple Seafoam gas treatements and an intake treatment
- Serviced transmission fluid ~5.5 qts and replaced transmission filter
- Replaced all coolant
On top of regular oil changes of course. Got a couple samples looked at from Blackstone to gauge the engine condition and waiting for the last one for the transmission fluid. At this point, I feel like it's in super healthy shape. I've learned a lot about maintenance this past year.
