Well, The Pork Chop Express (2006 FX4) just turned 70k.
I did the plugs and a trans flush last year at 60K.
It needs an oil change. Would this be a good time for front and rear diff fluid and transfer case?
Also, brakes are coming up soon and I would like to do something better than stock .
The stock shocks are looking a little saggy, so I think some of Bilstein 5100 will be on the way some time this year.
Other than oils and fluids, what else should I be looking for at this mileage?
Thanks!
