Parts for your 2009 Nissan Navara-Engine mount

2009 Nissan Navara engine mount — purpose, service tips, and when to replace

Engine mounts are absolutely fitted to the 2009 Nissan Navara (D40). This isn’t a “not used” item. Technical sources including the Nissan D40 Navara/Frontier Workshop Manual (Engine Mechanical, Engine Mounting), the Nissan FAST Electronic Parts Catalogue for D40 (listing LH/RH “Insulator—Engine Mounting”), and common workshop references such as Haynes/Gregory’s guides confirm left and right engine mounting insulators for both YD25DDTi diesel and VQ40DE petrol variants.

On the 2009 Navara, the engine mounts do two big jobs: hold the engine at the correct height and angle, and keep noise, vibration and harshness out of the cabin. They’re typically hydraulic rubber insulators that absorb engine movement under throttle and over bumps, protecting driveline angles, the exhaust and intercooler piping, as well as the firewall and subframe. When healthy, they help the ute feel tight and smooth, when tired, the whole vehicle can feel rough and clunky.

Symptoms of worn mounts owners often report include:

• Noticeable vibration at idle or after start-up
• Clunk or thud on take-off, gear changes, or when shifting from Drive to Reverse
• Excessive engine rock when the bonnet’s up and the throttle’s blipped
• Rubber perishing, collapsed mount height, or fluid weep from a hydraulic mount

As part of regular servicing, a quick visual and pry-bar check goes a long way. Workshops usually inspect mounts every 40,000–60,000 km, or sooner if the vehicle tows, works off-road, or has had an oil/diesel spill around the mounts (petroleum exposure accelerates rubber degradation). Under load, a simple power-brake test can reveal excessive engine movement. If one side is failed or significantly sagged, replacing mounts in pairs is smart practice for balance and longevity.

Replacement is straightforward with the right gear: support the engine from above or with a jack and timber under the sump, remove skid plates for access, loosen the through-bolt and bracket fasteners, then lift the engine slightly to swap the insulator. Torque fasteners to spec with the engine resting at normal ride height (refer to the D40 workshop manual for torque values and sequence). After fitment, check clearances for the exhaust, shrouds, and intercooler hoses, and give the transmission mount a once-over too. Quality OEM or reputable aftermarket hydraulic mounts are recommended, shimming or mixing mount types is a false economy that can introduce vibration.

Done right, fresh engine mounts restore that factory feel and prevent knock-on damage to hoses, brackets, and driveline components. For a hard-working Kiwi or Aussie D40, this small bit of maintenance pays off every drive.

Popular questions about 2009 Nissan Navara engine mounts

How long do engine mounts last on a 2009 Navara?
Many last 120,000–180,000 km, but heavy towing, corrugations, oil exposure, and performance tunes can shorten that. Regular inspection during services helps pick up early sagging or leaks before vibrations get worse.

What are the signs of a bad engine mount on a D40?
Tell-tales include harsh vibration at idle, a knock on take-off or when shifting into gear, visible cracks or fluid leaks at the mount, and the engine sitting lower on one side. Excessive engine rock with modest throttle under the bonnet is another giveaway.

Is it safe to drive with a failed engine mount?
Short distances at gentle speeds may be possible, but it’s not ideal. A collapsed mount can stress the exhaust, hoses and intercooler piping, upset driveline angles, and make other mounts or the transmission mount fail sooner. Prompt replacement is the safer, cheaper path.
