Parts for your 2012 Nissan Navara-Coil springs

2012 Nissan Navara (D40) coil springs — what they do and when to replace

Based on technical references including the Nissan Navara D40 Factory Service Manual (Front Suspension section), Nissan FAST parts catalogue, and major suspension catalogues (e.g., Monroe, KYB), coil springs are absolutely relevant to the 2012 Nissan Navara. The D40 uses coil-over front suspension (independent double wishbone with a coil spring over the shock/strut), while the rear end runs a live axle with leaf springs. So, for this model year, coil springs are fitted at the front, not the rear.

Up front, the coil springs carry vehicle weight, keep ride height where it should be, and let the front wheels track the road while absorbing bumps. Paired with the shocks, they manage body control under braking, cornering and corrugations. On Navaras that have bullbars, winches or dual batteries, front coils work especially hard, so correct spring rate matters for both comfort and control.

As part of routine servicing, the front coils should be inspected for sag, cracks (particularly at the ends), chipped paint leading to corrosion, and coil bind marks. Listen for clunks or creaks over speed humps and watch for uneven tyre wear or a nose-down stance — all can hint at tired coils or related hardware like strut mounts.

• Check ride height side-to-side and against spec, a droop on one corner often points to a fatigued spring.
• Look for rust pitting or broken “pigtails” at the spring ends.
• If fitting accessories up front, confirm the spring rate suits the added weight.

When replacement time comes, it’s smart to do coils in axle pairs and match them with suitable shocks. Use the correct spring rate for the VIN/trim and intended load. Because coil springs store a lot of energy, only use a quality, approved spring compressor — or get a workshop to handle the swap. Refit torque should be done at normal ride height to avoid bush preload, and a wheel alignment is a must afterwards.

• Consider replacing strut top mounts, bearings, bump stops and dust boots while you’re there.
• Heavy‑duty or raised coils can improve stance with accessories, but they change geometry — plan for alignment, check CV angles on 4x4s, and ensure any height change complies with local rules (ADR in AU, LVVTA guidance in NZ).

Popular questions about 2012 Nissan Navara coil springs

Do 2012 Navaras have rear coil springs?
No — the D40 Navara runs rear leaf springs from factory. The front uses coil-over struts. If someone’s mentioned rear coils, they’re likely thinking of the later NP300 (D23) Navara, which introduced a rear multi‑link coil setup on many models, or the Pathfinder R51, which is a different vehicle.

How long do the front coils typically last?
There’s no set interval. With normal use they can last well over 150,000–250,000 km. Frequent towing, corrugations, added front accessories or coastal corrosion can shorten their life. Replace them if ride height sags, a coil is cracked, or handling and tyre wear point to a loss of spring rate.

Can they be replaced at home?
Yes, but only with the right tools and know‑how. Front coils are under heavy tension — use a quality spring compressor and follow the factory procedure. If unsure, have a suspension specialist handle the job, then finish with a proper alignment.
