Lexus GX and LX vs. RX and NX: Frame and Unibody Straightening

The Lexus GX and LX are body-on-frame SUVs while the RX, NX and ES are unibody. Learn how that changes structural straightening.

Two Kinds of Lexus Structure

The Lexus GX and LX are rugged, body-on-frame SUVs that share engineering with Toyota's Land Cruiser family. The RX, NX, TX, ES and IS are unibody vehicles. After a collision, the approach to straightening depends on which type you drive.

Body-on-Frame: GX and LX

On these SUVs, the body sits on a separate ladder frame. We measure the frame and the body mounting points independently. Frame horns, crossmembers and rear rails are common damage areas. Because these vehicles are often used off-road, underbody and frame damage may also come from trail incidents.

Unibody: RX, NX, TX, ES

On unibody Lexus models, the rails, aprons and floor are integrated into one structure. We measure the body at multiple points and restore dimensions with controlled pulls where Lexus allows. Ultra-high-strength steel parts beyond repair limits are replaced.

Signs of Structural Shift

  • Doors or liftgate that close differently
  • Uneven panel gaps
  • An alignment that will not stay centered

After Straightening

Panels are fitted, alignment is set and Lexus Safety System+ is calibrated as required.
