First-Generation FR-S, BRZ and 86 Steering Columns and Intermediate Shafts: Branch, Safety and Contents

Supported service relationships are SU003-00870 -> SU003-11726, SU003-00838 -> SU003-11191, 34500CA040 -> 34500CA041, 34500CA050 -> 34500CA051, 34500CA100 -> 34500CA101, 34500CA161 -> 34500CA162 and 34170CA010 -> 34170CA011. SU003-00869, SU003-06815, SU003-06816, SU003-07694, SU003-07695, SU003-08231, SU003-08232, 34500CA160, 34500CA170 and 34500CA171 remain parallel or production/equipment-specific anchors unless a current VIN EPC proves otherwise. No cross-badge supersession is asserted, and a lower shaft is not a complete steering column.

Start with both VINs/builds and the recipient's current badge-specific EPC result; transmission alone does not select the column because checked catalogs expose multiple grade/equipment branches within transmission groupings. Require readable labels and exact-item photos of the column tube, electric-assist assembly, tilt/telescope mechanism, upper shaft/spline, lower coupling interface, mounting bracket and studs, electrical connectors, smart-entry or conventional-key housing provisions and automatic-transmission key-interlock hardware. Itemize wheel, airbag, clockspring/roll connector, combination switches, ignition/lock parts, trim, brackets, lower shaft, fasteners and harnesses because complete is not a contents list. Reject any collapsed capsule or shortened shaft, bent bracket, loose or notchy bearing, spline damage, radial play, rust at joints, cracked casting, water/fire exposure, airbag-deployment or frontal-impact donor, drilled/cut/welded/tampered housing or unknown repair. The checked service information treats the electric-assist column as impact-sensitive, warns against pulling or striking it, requires restraint/roll-connector precautions and calls for torque-sensor zero-point and steering-rotation-angle calibration after applicable service. Use a qualified steering/restraint technician and current OEM procedures. Lawful key or immobilizer service stays separate; this guide provides no bypass instructions.

No universal aftermarket steering-column or intermediate-shaft replacement is recommended. A verified new badge/VIN-specific OEM service assembly, the buyer's original professionally rebuilt unit where a qualified specialist documents scope and safety acceptance, or a clean exact-identity used donor is the bounded path. Quick-release conversions, welded shafts, altered collapsible sections, steering-lock deletion and race-only columns are engineered changes outside this guide.

A steering column is a collapsible electric-assist safety assembly, not a generic tube. Match both VINs/builds, badge-specific current EPC identity, production/grade, smart-key or conventional-key and automatic-interlock provisions, upper/lower interfaces and written contents. No cross-badge supersession is asserted. Reject impact, deployment, collapse, play, spline damage, corrosion, water/fire exposure, tampering, cutting or welding. Keep clockspring/restraint and lawful key service separate; use qualified installation and required torque-sensor/steering-angle calibration.
