1989-1998 Nissan 240SX S13/S14 Factory Upper Steering-Column Assembly Identification

Checked S13 complete-column service links are 48805-40F60 / 48805-40F61 -> 48805-40F63 and 48805-40F62 -> 48805-40F64. S14 48805-70F00 and 48805-70F81 are separate catalog branches, not a supersession chain. 48821-40F60 and 48820-70F83 are generation-specific upper-shaft identities. No S13-to-S14, HICAS-to-non-HICAS, fixed-to-tilt, body, transmission, lock/switch, restraint or lower-interface interchange is asserted.

Begin with both 17-character VINs, build dates and actual installed labels/stamps, then identify S13 or S14, US/LHD body, HICAS/non-HICAS where applicable, manual/automatic equipment, tilt/fixed provision and the exact upper column/shaft/jacket branch. Compare overall uncollapsed dimensions, upper and lower splines/interfaces, jacket and bearing condition, dash/floor brackets, tilt hardware and wheel/hub/contact or spiral-cable interface. Treat steering wheel, airbag where equipped, spiral cable/contact equipment, cancel cam, combination switches, ignition switch, lawful lock housing/cylinder, covers, wiring, brackets, boots and hardware as separate unless individually shown and listed. Nissan service material says the column is collapsible, warns axial impact can collapse it and directs replacement when tilt/collapsible damage is suspected; reject impact or deployment donors, dimension loss, bent or cracked jacket/brackets, prior pulling, drilled/cut/welded modifications, bearing play/binding, spline damage, corrosion, fire/flood exposure, cut wiring and tampering. Preserve SCH-0029's lower/intermediate shaft, lower joint, coupler, U-joint and solid-bushing scope and SCH-0027's rack scope. Use qualified steering/restraint service, follow current VIN-specific SRS precautions and verify straight-ahead centering, smooth lock-to-lock operation and alignment. No theft, immobilizer, ignition-lock or restraint bypass instruction is provided.

No checked aftermarket complete upper column establishes a factory interchange or supersession. An exact undamaged factory column is the reference path only after VIN, identity, dimensions, equipment, contents and qualified safety inspection resolve. Quick-release, universal, race, cut-and-weld, swap and solid-bushing paths change the steering/restraint assumptions or intrude on SCH-0029 and are excluded.

US/LHD S13/S14 240SX upper collapsible columns only. Match both VINs/builds, S13/S14, HICAS status where applicable, manual/automatic and tilt/fixed equipment, exact upper identity, dimensions, interfaces and every included lock/switch/restraint-adjacent part. Exclude all SCH-0029 lower/intermediate hardware. Reject impact, collapse, deformation, binding/play, tampering and cut/welded modifications; use qualified steering/restraint service and no bypass procedure.
