You’ve checked there is nothing stuck in the tyre…?
Edit; how certain are you that it is that wheel? Noises from underneath can be misleading as to which corner there are coming from (if indeed a corner at all… prop?)
Assuming all model years are the same (I believe they are), the rear driveshaft nuts on an F2 are 395Nm, or 291 lbf-ft.
And you should use a new nut 😉
You still need a big torque wrench.
The vac bags are a good call - we have them somewhere (never used 🙄).
I think the OP is doing a ‘round trip’, as opposed to one way, but those seats are a pain to ‘store’!
If you need as much space as poss then take out the seats, get yourself some of those vac bags for soft stuff, they save a huge amount of space.
Dont forget you have to go back for your seats :).
