rear rotors extra excessive play

[Stang24]

Having this chirping noise coming from the rear wheels just over 500 miles on the car. Took off the wheel and the rotor has some excessive play in it. Here’s the noise and that video of the rotor. Thinking the noise is wheel bearing or now rotor related…..

I've seen some loose fitting rotors over the years so that's not unusual. How tight were those lug nuts on when you first removed the wheel? Make sure you torque the lug nuts to 150 lbs/ft (that's what's required for the s550, I assume its the same for the s650). That should sandwich the rotor in there well enough to prevent any movement. If that doesn't work, back to the dealer.

Checked them all and torqued to 150 the sound is still present

Did you spin by hand the same way you did just the rotor to see if it’s still doing it after torque…

150ft/lbs on the lug nuts? that is WAY too high

that's what Ford calls for

Oh wow, nvm then.

It definitely is not. That’s what it states

 

[slowjim]

I stand corrected, on cars I've owned in the past it was closer to 90-110 range.

I was surprised also. Its was always 95 to 110. Never had a wheel fall off in over 50 years. The 24's must have some super studs.

Axle nut in combination with the axle thrust washer is a plausible issue. Take it in sooner rather than later.
