Parts for your 2010 Nissan Navara-Engine mount

2010 Nissan Navara (D40) engine-mount — what it does and when to replace it

Engine-mounts are absolutely fitted to the 2010 Nissan Navara (D40) and are essential to the vehicle’s design. This is supported by Nissan’s Electronic Service Manual for the D40 platform, which includes an Engine Mounting section specifying left/right mount insulators, brackets and torque procedures, the Nissan FAST parts catalogue that lists engine-mount insulator assemblies for both YD25DDTi diesel and VQ40DE petrol variants, and mainstream workshop manuals used in AU/NZ that schedule inspection of engine-mounts during routine servicing.

On the 2010 Navara, the engine-mounts (often called mount insulators) secure the engine to the chassis crossmember while isolating vibration. They’re designed to keep noise, vibration and harshness down in the cab, hold the driveline in the right spot under load, and prevent excess movement that can stress hoses, exhaust joints and the gearbox mount. Diesel utes like the Navara work hard—towing, corrugations, and stop–start use all load up the mounts—so staying on top of their condition is good preventative maintenance.

Typical clues a mount’s on the way out include a rougher idle in Drive, a thump or clunk on take-off or when shifting from Reverse to Drive, more vibration through the floor, or visible sag/cracking of the rubber. Hydraulic mounts may weep fluid when they fail. A quick visual under the bonnet and from below on a hoist, looking for collapsed rubber, torn bonds or contact marks, is worthwhile every 20–40,000 km during scheduled services.

• Replace mounts in pairs when practical to keep NVH balanced, especially on the YD25DDTi.
• Support the engine safely with a jack and timber block or an engine support bar before loosening hardware.
• Loosely fit new mounts, lower the engine to normal ride height, then torque all fasteners to the specs in the Nissan service manual.
• Check exhaust flex, shifter linkages, and the gearbox mount after fitment for alignment and clearance.

Quality matters here: genuine or reputable aftermarket mounts generally last longer and control vibration better. In normal use, owners often see 120,000–200,000 km from mounts, heavy towing, lift kits or harsher conditions can shorten that. If the ute is shuddering at idle or knocking on take-off, don’t leave it—excess movement can crack exhausts and stress driveline components, costing more than the mounts ever will.

Popular questions about 2010 Nissan Navara engine-mounts

How long do engine-mounts last on a 2010 Navara?
Many owners see 120,000–200,000 km, but frequent towing, off-road work and higher idle vibration in diesels can reduce life. Regular inspections during scheduled services help catch early wear before it turns into NVH or driveline issues.

Is it safe to drive with a worn engine-mount?
It’ll usually still drive, but it’s not ideal. Excess engine movement can stress the exhaust, hoses and the gearbox mount, and you may feel more vibration and hear clunks. Replacing the faulty mount sooner protects the rest of the driveline.

What does replacement typically cost?
In Australia and New Zealand, parts are commonly $120–$300 per mount (aftermarket to genuine), with 1.5–3.0 hours of labour depending on engine and access. Prices vary by shop and whether mounts are done singly or as a pair.
