2008 Nissan Navara Suspension Bushes: What They Do and When to Replace Them

Based on technical sources including the Nissan D40 Navara Factory Service Manual (FSU/RSU/FA sections), the Nissan electronic parts catalogue (FAST/EPC), and well-known aftermarket catalogues from SuperPro and Nolathane, suspension bushes are absolutely used on the 2008 Nissan Navara (D40). These references list front control arm bushes, stabiliser (sway) bar bushes, rear leaf spring eye and shackle bushes (on leaf-sprung utes), and shock absorber eye bushes as serviceable components.

On the 2008 Navara, suspension bushes act as the cushion between metal components, controlling movement while soaking up noise, vibration and harshness. They help keep wheel alignment steady under braking and cornering, sharpen steering feel, and reduce knocks and rattles over corrugations. Rubber bushes are common from factory for comfort and isolation, while polyurethane upgrades are popular with owners chasing crisper response and better durability under towing or off-road work.

For ongoing servicing, a workshop will usually:

• Inspect bushes every 20,000–30,000 km (or at each major service) for cracks, splits, oil swelling, or excessive play.
• Check for symptoms: clunks over bumps, vague steering, wandering, vibration, uneven tyre wear, and brake shudder that isn’t rotor-related.
• Look closely at front lower control arm bushes and rear leaf spring eye/shackle bushes, as these are common wear points on D40s.

When replacement’s due, it pays to do bush pairs on an axle to keep handling balanced. Many workshops recommend replacing complete front control arms if bushes are heavily worn or the ball joints are tired, as that can save labour and ensures everything’s tight. If fitting polyurethane, a suitable grease is required during assembly. Bush bolts should be tightened at normal ride height (with the ute’s weight on its wheels) to avoid preloading and early failure. After any bush or arm replacement, a full wheel alignment is essential.

Choosing rubber vs polyurethane depends on use. Rubber keeps the Navara smooth for daily driving, while quality polyurethane can sharpen response and resist deformation under loads. Either way, sticking with reputable brands and following torque specs from the D40 service manual will keep the suspension quiet, compliant and reliable across Aussie and Kiwi roads and tracks.

• Popular questions about 2008 Nissan Navara suspension bushes

What are the signs the bushes are worn on a 2008 Navara?
Owners often notice clunks over speed humps, vague steering on the highway, or a shimmy under braking. Uneven or rapid tyre wear and a wandering feel in crosswinds can also point to tired control arm or leaf spring bushes.

Visual checks usually reveal cracked rubber, perished edges, or off-centre sleeves. Any oil contamination from leaking shocks can accelerate deterioration.

How often should the bushes be checked?
A practical interval is every 20,000–30,000 km, or sooner if the ute tows, carries heavy loads, or sees corrugations and off-road use. Include the inspection with regular servicing so issues are caught before they affect tyres and alignment.

Rubber or polyurethane—what’s better for a D40?
For comfort and factory-like NVH, quality rubber is the safe pick. For sharper handling and durability under load, polyurethane is a solid upgrade. Mixing is fine—many owners keep rubber in high-NVH spots and use polyurethane in sway bar or control arm locations for better precision.
