2006 X5 3.0 Rotor Runout Specs
 

Anyone know the runout specs for the rotors? I want to check for warp.

Thanks in advance.

The maximum endplay for a bearing is 0.004” (0.100 mm)
the maximum allowable runout at the rotor friction surface is 0.002 inch (0.050 mm) as stated by most manufacturers.

Note: hub mounting area not cleaned when replacing the rotors is the #1 suspect of rotor issues. Ask me how I know......

Thank you for that information. I thoroughly cleaned mine when I replaced the rotors. I also did it/do it when I pull my wheels. Started putting anti-seize on the hub and haven't had any trouble removing wheels since. Thanks again.
