Parts for your 2005 Nissan Navara-Coil springs

2005 Nissan Navara coil springs: what’s fitted and what matters

For the 2005 Nissan Navara sold in Australia and New Zealand, coil springs are relevant only if the vehicle is the newer D40 platform. The earlier D22 (still sold in 2005) uses front torsion bars and rear leaf springs, so it does not have coil springs at either end. The D40, launched in 2005, runs coil-over struts at the front and leaf springs at the rear. This split is confirmed in Nissan’s factory literature: the D22 service manual’s Front Suspension section specifies torsion-bar IFS with no coils, while the D40 service manual describes a front strut with a coil spring assembly. These layouts also align with period specifications published for AU/NZ models.

For D40 owners, the front coil springs carry the ute’s weight, set ride height, and work with the struts to control body movement on-road and off-road. They’re designed to flex repeatedly without sagging, keeping steering geometry in check and the tyres planted, especially when the tub’s loaded or a bull bar and winch add weight up front. Over big kilometres, heavy towing, corrugations, or coastal exposure, coils can fatigue or corrode. Tell-tales include a nose-down stance, uneven ride height side to side, bottoming out over speed humps, knocking when turning, or odd tyre wear from geometry going out of whack.

There’s no fixed replacement interval for D40 coils, but they should be inspected at routine services—look for flaking paint, pitting, rust, broken ends, or polished “coil bind” marks. If one side is tired, replace coils in pairs to keep height and handling consistent. Good practice during replacement includes:

• Choosing a spring rate matched to accessories and GVM, not just a lift height.
• Renewing strut top mounts, bearings, and insulators if worn.
• Torqueing fasteners at normal ride height to avoid bushing pre-load.
• Finishing with a wheel alignment (caster/camber/toe) and a quick headlight aim check.

If the Navara is a D22, coil springs aren’t used because its independent front suspension relies on torsion bars to provide the spring rate, with rear load handling via leaf springs. That design was chosen for durability, packaging, and tuneability for payload—fitting coil springs to a D22 requires extensive conversion and engineering certification.

FAQs

Does my 2005 Navara have coil springs?
It depends on the chassis. D22 models have torsion bars up front (no coils), while D40 models have front coil-over struts. A quick check: look for a strut tower with a spring wound around the shock (D40) versus torsion-bar adjusters running back along the lower control arm (D22). Your build plate or model code (D22 vs D40) also gives it away.

How often should front coil springs be replaced on a D40?
There’s no set kilometre limit. Inspect at every service and replace if there’s sagging, damage, corrosion, or if ride height is uneven. High-load touring, heavy accessories, and harsh roads accelerate wear—many owners refresh coils and struts together to restore ride and handling.

Can a D22 be converted to coil springs?
It’s technically possible with aftermarket coil-over conversions, but it’s complex and costly, affects compliance, and generally needs certification. For most D22 owners, a quality torsion-bar, shock, and bushing refresh is the smarter path.
