....replaced, and NONE of the rotors, front or rear, are attached to the hub. With the wheels off of the car, I can wiggle the rotor all around (forward and back until the lug bolts stop the rotational progress, and in-and-out like a spinning top about to topple over). WTF!!!!?

Please let me know ASAP before I storm into the repair shop in the morning!

Thanks,
DD.

um. i think it's supposed to do that?

when i take off my wheels they just come off lol... i don't think they're supposed to be screwed down to anything.

I guess I'll have to be circumspect as I discuss this in the morning. I'll try to call the dealer in the morning.

Thanks!

That's normal. The rotors are held on when you put the wheel back onto the car. The rotors are sandwiched between the wheel and the wheel hub.

Yes. This is normal.

1. The Wheel(rim) torqued down to the Hub holds the rotors to the car.

2. With the Wheel off... the rotors can wiggle...but not come loose because the Calipers/Pads and Stud Bolts are still holding them up.

*the only rotors that don't wiggle around are...

...the old rusty rotors that have rusted and seized on to the hub...

^very good point. i even go as far as putting anti-seize on the hub and back of the rotor to keep them from heat fusing together. you may want to put some on the threads of the studs too. but yeah it is normal for them to wiggle when the wheel is off

Ronsully

some cars have small screws that hold the rotors on; however, i think those screws are on there to make the original assembly easier (ie - when the car was manufactured).

...need that confirmation :-)


thanks for the replies!

BTW, my BMW has two set screws to hold the rotor onto the car, and the LS, gen 1, had them also. I didn't find a rotor changing website and couldn't verify this until the morning.
