Low 40’s is not terrible, but, you will almost certainly need new shocks all around, because with 5 owners, chances are they didn’t drop the coin on new or rebuilt shocks. For 2017’s, you have a few things to check for
1) oil leak from the plastic oil pan. It’s rare, but when it happens, it’s exceedingly difficult for most stealership service departments to fix. You have to get under and look with a powerful light and feel around.
2) cam phaser noise. you need a cold soak startup. That means at least 12 hours since the last startup. if it sounds like marbles in a can, they need to repair the cam phasers. Service records, Oasis & Fordpass would show if the service memo ( or was it a TSB ) was performed to change the programming.
- I seem to recall, if that programming caused shuddering, to back it off and if it was backed off, that could be a sign of premature engine wear. Someone backstop me here.
3) if it doesn’t have a moonroof, inquiring minds want to know WHY YOU HAVE NOT ALREADY PURCHASED THIS UNICORN?
the moonroof is an infamous part for failures on the f series with the tracks breaking most frequently. it’s a costly repair that can be avoided.
- always pop the moonroof to the vent position FIRST, then close.
- if it makes a popping sound, repeat.
- if no popping sound, close and move the glass to the rear. The ‘pop’ is the glass sticking to the gasket and that force can often be enough to break the tracks.
- regularly grease the moonroof gaskets with Krytox grease.
4) once the truck is warmed up, get a long, robust test drive. You’re going to need to be able to get hard on the throttle a few times in normal mode and sport mode. Make sure the shifting is acceptable. Sport should be a bit more aggressive up and down but beware of really hard shifts, or really lazy shifts.
5) lifted Raptors tend to wear the front drive components more. There have been a few FRF who have found this out and were not covered by warranty. Again, a good test drive to be sure.
