Well this turns out to be a very interesting question, much more so than I originally thought it would be.
First your 1D "probably" was equipped with hydraulic folding wings, particularly if it's a Navy carrier based version, they moved together not independantlly.
Now for the "probably" part :
The F4U-1 had fixed wings, many models there after intented for land based units retained the fix wing configuration, particularly close support Marine units (low attiutde version)
Goodyear versions the FG series were "mostly" fixed wing but some had manual folding wings, and could be folded independantly.
I found it hard to determine exactly where and the how the folding verse fixed wing version designated. Suffice it to say "carrier based versions had folding wings", "some land based versions had fixed wings".
Wow, who'd have thunk it would be the complicated ?
