Official summary
2001-2004 MODEL YEAR TACOMA FRAME INSPECTION FOR RUST PERFORATION. Before raising the vehicle on an alignment rack (or lift), visually inspect the entire frame assembly (top, side and bottom surfaces of the frame rails) for visible signs of perforation. Visually inspect the frame assembly for rust/corrosion, and follow the steps provided.* * CAUTION: Use protective eyewear and gloves when performing the under-vehicle inspection as rust and debris may flake off.
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
