US S13 and S14 240SX Rear Suspension Members: 2WS, Super HICAS, Production and Condition Identification

Checked whole-member service links are 55400-50F00 -> 55400-50F01; 55400-52F00 -> 55400-52F01; 55400-35F13 and 55400-40F00 -> 55400-52F05; 55400-68F01 -> 55400-68F00; and 55400-68F10 -> 55400-85F00. The catalog reports MultiSupersession for 55400-68F12, so no single undocumented successor is asserted. No chain is asserted for 55400-68F15. These service links do not establish S13/S14, 2WS/HICAS, transmission, trim or imported-market interchange.

Begin with recipient and donor 17-character VINs, production dates, body/generation, factory steering equipment and actual-piece photographs. On S13, prove 2WS versus Super HICAS/4WS and verify the toe-link/HICAS actuator interfaces. On S14, prove production, STD/SE and transmission catalog branch even though a seller may group all 1995-1998 cars together. Match the four body-mount positions and bushings; differential nose and rear-cover mounting; lower-arm, upper-link and toe-link pickups; stabilizer brackets; shock/spring and exhaust clearances; stays; sensor and parking-brake routing; and every threaded hole. ABS may change loaded differential, axle, sensor, harness and brake contents even where the checked whole-member listing is not separately ABS-coded. Require a written bare-versus-loaded inventory. Reject deformation, shifted pickups, cracked welds, torn or elongated holes, serious scale or perforation, collision marks, heat, filler, grinding, non-factory welds, straightening, reinforcement or coating that conceals condition. S13 and S14 geometry, mounting spacing, lower-arm/toe-link interfaces, differential mounting and exhaust brackets differ; do not treat cross-generation installation as routine interchange. Inspect and measure the recipient body mounts separately using qualified collision/alignment equipment. Follow the exact factory procedure with rated lifting/support equipment, required hardware replacement and final four-wheel alignment. This guide provides no pull, weld or structural-repair instructions.

A correctly identified, straight and unmodified factory member is the accepted restoration path. SCH-0021 retains insert-versus-full bushing choices, and SCH-0045 retains differential/rear-cover selection. Solid, polyurethane or conversion bushings, cross-generation conversions, fabricated/tubular members, relocated pickups and reinforced drift parts change geometry, noise/vibration, fatigue, crash and road-use assumptions; they are not OEM supersessions or proof that a bent, cracked or corroded member is reusable.

US/LHD 240SX only: 1989-1993 S13 Coupe/Fastback, 1992-1994 Convertible and 1995-1998 S14 Coupe. Confirm both VINs/builds, S13 versus S14, 2WS versus Super HICAS, transmission/trim/production branch, ABS-related loaded contents and exact member identity. Itemize every differential, arm, link, hub, brake, sway, sensor and hardware component. Reject cracks, deformation, torn mounts, severe corrosion, heat, welds, straightening or hidden repairs. Cross-generation conversion is not routine interchange. Require actual-piece photographs, qualified geometry inspection, safe lifting and final alignment. No structural-repair instruction is provided.
