CAUTION
Vehicles built before March 25th, 2019 have 1st generation front subframes. Vehicles built on March 25th, 2019 and after have 2nd generation front subframes. 1st generation subframes require special M8 bolts (torque 27 Nm) to install 2nd generation steering racks. Refer to the Electronic Parts Catalog for the latest information. 2nd generation subframes cannot accommodate 1st generation (discontinued) steering racks. A 2nd generation steering rack must be installed.
