Great Designs in Steel 2023 Presentations: A Closer Look - Toyota TNGA-F Full- Frame Platform
I-CAR · August 23, 2023 · Toyota, Lexus
Summary
The Toyota TNGA-F full-frame platform, used on the Tundra, Tacoma, and Sequoia, utilizes Tailor Welded Blanks (TWB) combining high-strength and ultra-high-strength steels (590, 780, and 980 MPa) to reduce weight while maintaining rigidity. This design introduces complex repair challenges, requiring technicians to consult specific Toyota CRIBs and service manuals for frame component repairs and high-voltage safety precautions.
What to do on the job
Consult Toyota CRIBs #161, #57, and the vehicle-specific service manual to identify exact steel strengths (up to 980 MPa) and approved repair or replacement procedures before performing any frame repairs.
How to use it
Use this document to justify the necessity of researching OEM-specific frame repair guidelines and CRIBs on newer Toyota trucks and SUVs. It highlights that traditional frame repair methods do not apply to TNGA-F platforms due to the sensitive mix of high-strength and ultra-high-strength Tailor Welded Blanks, and justifies billing for OEM research time and specialized safety precautions if a high-voltage battery is present.
