Nissan Stagea: M35 Rear Multi-Link Lower Arm Bush Failure

The M35 Stagea uses a five-link rear suspension design with multiple rubber compliance bushes in each lower control arm. The front-lower arm inner compliance bush and outer pivot bush are the primary failure points, degrading through age, Australian road surface loading, and lack of lubrication after import. As the bushes lose stiffness and develop circumferential cracking, rear axle toe geometry shifts under braking and lateral loading, producing rear-end wander at motorway speeds and imprecise straight-line tracking. Under deceleration, degraded compliance bushes allow the rear wheels to adopt a toe-out attitude, which is a documented dynamic instability risk. Worn bushes also produce audible clunking over road irregularities. Correct repair requires pressing out and replacing all lower arm bushes and a subsequent four-wheel alignment to confirm geometry is restored to specification.

• Rear-end wander or instability at motorway speeds above 80 km/h
• Vague or imprecise straight-line tracking requiring constant small steering corrections
• Clunking or knocking noise from rear suspension when traversing bumps or dips
• Uneven rear tyre wear — feathering or accelerated inner edge wear indicating toe instability

1. 1

   Inspect rubber bush material for cracking, deformation, or separation from the metal sleeve.

2. 2

   Check rear tyre wear pattern across the full tread width for signs of dynamic toe shift.

3. 3

   If a workshop inspection is possible: With the vehicle on a hoist, grasp each rear wheel at the 9 and 3 o'clock positions and apply firm lateral load to check for bush deflection or play at the lower arm pivot points.

Parts involved: Ball joint.

≈A$660 to ≈A$1,750 at independent workshop rates, shown as an approximate guide in Australian dollars. That is for this job on its own, not for the car.

An estimate, converted to Australian dollars, for the repair as normally carried out. What a specific car costs depends on which part has failed and what it damaged on the way — treat this as the floor for a negotiation, not a quote.

• “Has the rear suspension geometry been aligned or checked since import?”
• “Have any rear suspension bushes been replaced?”
• “Does the car wander or feel unstable at highway speeds, or clunk over bumps?”

The failure described above is documented in published sources — owner forums, technical service bulletins, recall notices and workshop write-ups — held in our fault database. The inspection instructions and the cost estimate are KickTyres’ own interpretation of them, and it is a starting point for an inspection rather than a manufacturer statement.
