Correction code 3201220232012202
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 to install 2nd generation (currently available) 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 (currently available) steering rack must be installed.

  1. Remove the front subframe assembly. See Subframe Assembly - Front (Dual Motor) (Remove and Install).
  2. Remove the outer bolts that attach the steering rack to the front subframe.
  3. Inspect the outer bolts and determine their type.
    • If the bolts have M8 threads and minimal underhead fillet, the subframe is 1st generation and the steering rack is 1st generation.
    • If the bolts have M8 threads and an underhead bevel, the subframe is 1st generation and the steering rack is 2nd generation.
    • If the bolts have M10 threads, the subframe is 2nd generation and the steering rack is 2nd generation.
