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. When a 1st generation subframe is replaced with a 2nd generation subframe, the 1st generation (discontinued) steering rack, if installed, must be replaced with a 2nd generation (currently available) steering rack. Refer to the Electronic Parts Catalog for the latest information.
