488 Rear Wheel Fell Off!!!

I’ve also experienced loose lug nuts after tracking my 488. After having my right rear wheel start making a noise when driving back into the paddock, we checked the lug nuts and right rear could be turned by hand. After that, tightening after every session and noticing some loosening after each session, but only right rear. It’s a ccw track.

 

Yes, you will have to LOWER the torque or risk reshaping the bolts/hub contact points or potentially stretching/stripping the bolts.

 

Question: When they re-torqued the lugs each time at the track was it only the rear that was loose or was it all four wheels?

 

After every session torque wheels .... and before initial session install optimoly TA on all lug bolt seats.

Make sure pre-track inspection performed preferably at dealer and then again at track

Ferrari product is called MOLYKOTE D-321 R Anti Friction Coating

 

Does this issue occur solely if you are tracking the car or does it also occur after simply using the car for neighborhood cruises ?
It is crazy to me if you have to worry about and check how secure the lugs are every time you use the car.

 

I am a mechanic for a small race team. we have the 488 challenge car. a bit different of a setup as far as hubs go, but we had the same issue the other day. According to the other Ferrari race teams they are having trouble with the same wheel on the same side, but only that wheel. None of the other wheels are doing it. They are claiming that the alignment studs that go through the hub, rotor, and wheel loosen causing the wheel to not seat correctly on the rotor and hub. Not sure if you have those, but it might be worth a look.

 

Thanks for signing up and sharing your thoughts regarding this wheel issue!

 

Track only - If anyone here has recently been to Italy and have done anything track oriented you may not notice after every session there is someone there torquing the wheels when you come in.

 

Anyone know what the barcode on this OEM rim indicates ?
Do all OEM Ferrari rims have this barcode or does it mean that the rim was repaired as I am being told ?

Pm me

 

I heard of some one who it happen to and he never tracked his car

 

Not true it happens of the track as well ...

 

Time to start worrying.

 

Nope

 

Has Ferrari found an answer to this issue? Same thing happened to me and I have a 2018 488.
Left rear wheel issues on this car far too common.

 

Not alone and damage to vehicles is costly. Luckily haven’t read about anyone hurt yet.

 

Went to track maybe 8 laps on a short track stopped got water went back out did 2-3 laps thought I had a flat pulled over car was sitting on wheel and all5 lug nuts where within 50 ft I did not torque nuts first it was the left rear wheel. The car was in race mode , the car was serviced two weeks earlier

 

Search ...."Meaning of barcode on Ferrari OEM rim".
Had a similar experience but without question due to human error by a sponsor on this site.
Be careful who you let work on your car.
Nothing further to say about it.....it's all summed up in that thread.

 

Anyone find a solution to this issue?

 

On my 458 and my 488, I ran Titanium lug bolts. I torqued them all down to 74 foot lbs, using a torque wrench and never had any issues. Make sure you use a star pattern when you apply torque and also it's generally best to do it with the car jacked up a bit, so the weight is off the wheel/tire being secured. Do not use any oil or anti-seize on the threads.

Put about 1000 miles on my 488, before I sold it. Prior to taking it to the dealer, I removed the Ti bolts. They were still plenty tight.

Something to keep in mind, if you torque bolts, then "re-torque" them, generally you are upping the installed torque. The proper way to verify torque is to loosen the bolts, then re-torque them to the proper specs. Simply applying more and more torque (without backing things off in-between) is a recipe for pulled threads.

In fact, I would check your car to see if the threads where the lug bolts go are okay. I'm not sure if the person torquing your wheels down was using an impact gun or a torque bar or an actual calibrated hand torque wrench. Myself, I usually use either a digital torque wrench or a break-at-torque style when it comes to the lug bolts.

Absolutely....Don't let incompetent wannabe mechanics work on your car, wind up ruining your $300k+ car and risk your life in the process like I unfortunately experienced.
