Still have this isolated to under the hood for sure but as I mentioned before with the hood fully raised ..NO Noise when I rock truck.
Could be the latch..could be the black bar that run underneath most of the edge of the hood (not sure if it has a name??).
Will loosen and tighten some of the bolts on this piece..lube anything I can see that could use lube...and keep my fingers crossed.
I have the performance hood on my Daytona with a separate piece that inserts into the cut out..could be this too.
Be nice if it could hit 50 degrees so I can actually enjoy doing this.
