What is Disc Thickness Variation?
DTV is the end result and can have many causes behind the generation of this issue.
It can be one of, if not all of the following:
❗️ Wheel nut torque. Variations in torque values causing distortion of the disc rotor and hub. Typically associated with pneumatic rattle gun misuse.
❗️ Worn or damaged wheel bearing assemblies.
❗️ Not cleaning the hub mounting faces. Scoring or corrosion on the mounting face.
❗️ Bent or damaged wheel studs.
❗️ Irregular thickness of disc rotor anti-corrosion coatings on the mounting face.
❗️ Poor quality rotors. Out of tolerance spec.
❗️ Extraction screw pressure/damage.
