Common Suspension and Steering

Bushing Deterioration

Symptoms

Clunking, knocking, and general looseness in the suspension. Vague steering response. Uneven tyre wear. The car feels imprecise and wallowy.

Cause

The Z32's multi-link suspension uses numerous rubber bushings that degrade after 25--35 years. The rear lower control arm bushings are typically the first to fail and among the hardest to replace.

Fix

1 Replace all worn bushings. Polyurethane or Nismo uprated bushings are available for key locations. A full bushing replacement is a significant job -
2 budget $1,000--3,000 for parts, plus substantial labour

Cost mentioned in fix

budget $1,000

Common Suspension and Steering

HICAS Failure

HICAS warning light on the dashboard. Strange rear-end behaviour at low speeds (parking manoeuvres). The rear wheels may track incorrectly.

Minor Engine -- VG30DE/DETT (All Models)

Timing Belt Failure Risk

If the timing belt breaks, the valves collide with the pistons. The engine is destroyed. There is no warning -- the belt simply snaps and the engine stops instantly with catastrophic internal damage.

Common Engine -- VG30DE/DETT (All Models)

Spark Plug Access (Rear Bank)

The rear three spark plugs become fouled, worn, or fail, causing misfires, rough running, and reduced power.

Critical Engine -- VG30DE/DETT (All Models)

Oil Leaks

Oil seepage and dripping from multiple points -- valve cover gaskets, rear main seal, oil pan gasket, timing cover, turbo oil lines (TT), power steering lines, and various sensors.

Minor Engine -- VG30DE/DETT (All Models)

Overheating

Temperature gauge climbs, particularly in traffic or on hot days. Coolant loss. Steam from under the bonnet.
