Rear Right Knuckle/Spindle Assembly - 1990 300ZX Z32

The rear right knuckle assembly for the Nissan Z32 300ZX anchors the multi-link rear suspension, integrating the wheel bearing housing and brake caliper mounts for the twin-turbo chassis. When hunting in junkyards, focus exclusively on 1990-1996 Nissan 300ZX 2-seater donors; the 2+2 wheelbase variant uses geometrically different uprights that will not align correctly. Critical distinction: turbo models require knuckle 43210-40P00 featuring wider caliper mounting ears to accommodate the larger aluminum 4-piston calipers, while non-turbo cars use the narrower 43210-40P01 casting—attempting to mix these requires caliper bracket modification. Inspect lower control arm mounting bosses and toe link brackets for stress fractures, common after track abuse or curb impacts. Installation demands pressing the hub bearing squarely into the carrier and torquing the axle nut to 217-289 ft-lbs per Nissan service manuals. Verify ABS sensor tab integrity, as early JDM Fairlady Z castings lack the machined mount found on USDM 1990-1996 assemblies.
