  Q: How do you replace the rack and pinion on Nissan 300ZX?

  A: Raise the front of the vehicle and support it securely on jackstands, then remove the splash shield. Detach the bolts attaching the hydraulic lines to the crossmember and place a drain pan under the rack and pinion to disconnect the flare nuts where the hydraulic lines enter the rack and pinion, allowing the fluid to drain into the pan while plugging all openings to prevent contamination. Remove the bolt securing the upper end of the lower joint shaft to the steering column, then disconnect the bolt securing the lower joint to the rack and pinion gear and separate the two pieces, ensuring the alignment spacer matches the lower joint coupling retraction groove. Remove the cotter pins and nuts securing the tie rods to the steering knuckles, using a suitable tool to separate them. Loosen the bolts securing the rack-and-pinion to the crossmember without removing them, then remove the nuts attaching the front engine mounting insulators to the crossmember. Securely connect an engine hoist to the lifting eyes on the engine and lift it slightly to relieve weight from the engine mounts, checking clearances around the engine, especially the fan shroud and vacuum lines. Remove the rack and pinion mounting bolts and lift the unit from the crossmember; if it needs overhauling, consult a qualified mechanic. Install the rack and pinion onto the crossmember and secure it with the mounting bolts, then carefully lower the engine, ensuring the mounts align with their insulators before installing the insulator nuts. Reattach the tie rods to the steering knuckles, securing them with nuts and cotter pins, then install the top of the lower steering column joint shaft without the through bolt until the lower end is installed, ensuring the groove in the coupling aligns with the notch on the pinion housing before installing the upper end through bolt. Connect the metal hydraulic fluid lines to the pinion housing and the fluid lines to the crossmember, replace the splash shield, and finally remove the jackstands to lower the vehicle.
