   • Tighten all fasteners to the specified torque (50 lb-ft or 68 N·m).

9. Trim Heat Shields:

   • Trim the heat shields around the forward attachment bolt area to ensure they sit flat against the hitch bracket.

10. Reinstall Heat Shields:

    • Reattach the heat shields on top of the hitch brackets using the four (4) M6 bolts removed earlier.
