Replace Rear Nut HUb Hex P/N Ferrari 203780 Pozzy France and Ferrari Italy know this issue as soon you describe it. You can stay with this without dammage, but they can change this part during annual service.
Dude God Bless! Appreciate the thorough response from you and others. I'll take it to an indy shop next week and ask them to replace both rear nut hubs. I'm praying this will do the trick!
I have the same issue on my F8. If I let go of the accelerator and let it coast, I hear the squeaking. If I slowly coast through the neighborhood, it makes squeaking sounds like an old scooter. Took it to the official dealer (on warranty) twice and they just said it's stuff getting trapped in the brakes. Learned to live with it.
Man that’s unfortunate to hear that even at the dealer they can’t figure it out, even worse, seems like this issue carried over from the 488GTB and Pista and now went to the F8. Seriously Ferrari? Anyways, debating on whether I should have the Indie shop replace the hub nut as described above now or wait till my next service. Either way I’ll report back on this thread if and when I do it and if it does fix the sound.
I've had 4 cars with CCB's 2 Porsche and 2 Ferrari and they will squeal as they glaze up from light braking and dragging the brakes like in street driving sometimes but that was extremely are for me. My F8 is 4yrs old and does not make any squealing or chirping noise with the brakes. I truly believe that some cars when washed/detailed are getting tire shine on the rotor. This is extremely bad because as soon as your apply the brakes it does not wipe off the tire shine overspray but the instant heat opens pours and the silicone and tires shine gets bedded into the rotor and with the brake dust accumulates the pads vibrate and cause the squeals you guys hear. I only apply tire shine by spraying onto the sponge not near the wheel...actually I use a semi gloss tires dressing that squirts out onto the sponge. When I wash my cars I also wash the brakes...calipers and rotors with soap and water, including the wheel barrel/inside wheel...no wheel cleaner at all. Hose off the holes in the rotors too and brake dust gets in there and they can clog up. I've never have any issues like I read on these forums.
Trust me, I've done everything you mentioned. I've been reading this forum daily since I bought my car. I think I'm the worlds expert now on Ferrari chirping at coasting haha. There's some things that point to this being the brakes (chirping goes away when you brake actually) but things that don't point to brakes (chirping worse when turning left, only coming from one left sided axle, increasing with acceleration and then going away at higher speeds). I've washed my rotors, pressure sprayed them and even bought a non silicon tire dressing someone else recommend on this forum (probably you from years back ha). I've bedded the brakes by doing 10 stops from 80 to 20 mph. Slightly improved that night. Returned the next. Took it to the dealership for service and complained. They said the cleaned the brakes and it's gone. Came back on my drive home from the dealer. I've done everything and I'm encouraged and discouraged at the same time that this issue runs through many 488 gtbs, pistas and F8's. Go watch the CarWow guy do a video 7 years ago on the 488. He complains about the chirping. Watch Harry's garage review of the 488. You'll hear it chirping in the background. It's there. Some hear it more than others. Consider yourself lucky that Maranello spared you this Ferrari quirk! I'm gonna try the axle nut and see what happens...
Dang.... I hate to hear this. My 488 squealed too but washing the brakes stopped it for around 500 miles of street use. I didn't have the chirp when turning or coasting though. That leads me to believe the pre-fill was causing the pads to ever so slightly touch the rotors for what ever reason.
See that’s what I thought too but what doesn’t make sense is that even on light acceleration especially when you’re coming down a hill, with your foot in the gas, you’ll hear the chirp as well. My understanding is the pre-fill works when you take your foot off the gas, no while it’s on. I’m at my wits end. Let’s see if my mechanic has any insight. I’ll keep you all posted.
So I wanted to follow up with this issue. So often on this and other car forums, questions come up, people offer solutions, and no one ever follows up. Anyway, I took my 2017 488 gtb to my indy guy. Had him order the rear axle nut as another commenter had suggested would solve the issue. We took the car for a test drive prior and he definitely heard the chirp and he also thought it was coming from the left rear. He threw the car on the lift and spun each wheel. Nothing from the rear. Checked the play of the wheels in front of me. No play on the wheel with any motion or force he applied. Ruled out the bad axel nut and possible wheel bearing. However, even on light spinning of the front wheels, in particular, the drivers side, a faint chirp/squeak could be heard. Just for good measure he even accelerated the car on the lift to spin the back wheels to confirm it wasn't coming from there, and no chirp. He then took of a very slight amount (less than 1mm) off each pad in the front wheels. Took it home an no chirp! I was elated. Multiple drives no chirp!...until, after 30 miles or so, the chirp returned ! To be fair, it's much more quiet now, however, it's definitely still there. Just as before, only after the car is warmed up well and on coasting. Again, less volume than before, at least. Something tells me over time, it'll likely come back to full volume. He then suggested I do some hard braking to try and bed the pads since they were shaved down a bit and have a "fresh" face. I'm gonna try that when I get a chance over the next few days and will report if that solves the problem. Sounds like the noise is definitely brake pad related though. It's amazing how close the pads are to the rotors when the car in neutral or drive. Can definitly understand why many say it's pebbles or grime, etc. What I don't get is why it affects some cars and not others. Perhaps moving to a different pad down the line may be the answer. Thanks all for your insight and help.
