Diagnose "click" sound upon de/acceleration

Car is a 2013 FF with 9k miles. I've owned it approximately 2 months. Upon acceleration from a standstill, and at times when completely letting off the gas in 2nd gear around the 3.5k RPM mark, a noticeable "click" sound is heard when the windows are down (undetectable with windows up). Sounds like middle of the car to drivers side front wheel. I also heard it today when coasting in 1st gear and then applying throttle after the light turned to green. It mostly occurs upon the acceleration from a standstill. I do not remember hearing this sound 2 months ago. Fresh annual just completed by Ferrari dealer about 5 weeks ago.

Any idea what this could be from? It does not happen on shifts, just when there is a sudden load or unloading of the transmission. It is not a "thunk" sound but more of a "click". i was thinking perhaps the 4wd system but no clue to where to even start to look at things when I put it up on the lift or if there are other places to start looking first.

Thanks everyone!!

 

No modifications at all. Did just put original factory wheels back on it (prior owner had different Ferrari wheels on it).

Very odd and a bit annoying. Drive a mechanic around and he was at a loss for what it may be.

 

That is what I thought as well and I re-torqued all lugs to spec. Still a click.

 

I was unaware that this occurred. Maybe although the sound seems to be coming from more under the car than the front hood area. Worth a further inspection though (just need to find a way to test this).

 

I have not - I find it more determined by how much "loading" and "unloading" I am putting on the car/tranny/wheels.

 

It only happens upon mild to hard acceleration from a standstill or a low speed (1st or 2nd gear and almost every time it clicks) and when decelerating via a sudden lift off of accelerator (ie. 4k RPM in 2nd gear and a sudden lift off when the gearing slows you down a little suddenly).

Does not happen via a frequency based on time. Only upon the items mentioned above.

I'll drive it tonight and see if it has a click upon very slow acceleration from a stop. From my memory it does not.

The first thing I thought of was loose lug nuts due to the sound occurring from a loading/unloading of torque. Then thought maybe something with the AWD system "clicking" in but that doesn't seem to make sense to me.

 

Exactly!!

 

So the sound is now gone? Was any maintenance, tire change, fluid change, etc done around the time it went away?

I don't remember the sound a couple months ago but now I can't drive without noticing it! It is really bothering me that I don't know the cause and can isolate/fix it...

 

Spent some more time today trying to replicate the sound. I do believe it is more from the rear of the car (not front driver sound like originally thought). Occurs in straight lines (no turning required).
