A rear Z32 that knocks over every expansion joint after new lower ball joints usually still has a ruined seat in the knuckle. That insert is the taper the rear lower stud pulls into. Once it is scored, the joint cannot lock and the tap continues even with a fresh boot and castle nut.
The Genuine Nissan Rear Lower Ball Joint Seat is the same factory taper-18 insert used at the rear lower joint on Fairlady Z and 300ZX Z32. Two are required for both sides. It is the seat only—not the ball joint. Install a new seat whenever the rear lower joints come out so the taper lands on a clean surface.
At Terra Firma Automotive we supply this genuine Nissan Z32 rear ball-joint seat so the stud can actually clamp instead of rocking in old galling. Choose Terra Firma Automotive for authentic Nissan suspension hardware built for the Z32.
