The axle hub bolts, aka lug bolts, on the tC are known to be weak. Over tightening is the number one cause of failure where the bolt experiences stretching it twists off. While not so common, they have sheared off in hard racing and wrecks where it is predominately the front axle hub bolts that fail. It is highly recommended to replace all four sets of axle bolts with ARP quality studs, 12mm x 1.5mm pitch thread.

Note: It is highly recommended to set final lug nut torque with a torque wrench. Never use an impact or air ratchet for installing lug nuts.
