Parts for your 2015 Nissan X-trail-Strut mounts

2015 Nissan X‑Trail strut mounts — what they do and when to replace them

Strut mounts are relevant and used on the 2015 Nissan X‑Trail (T32). The Nissan Electronic Service Manual (FSU – Front Suspension) specifies a MacPherson strut front suspension that includes a top insulator/strut mount with an integrated bearing for steering rotation. Nissan parts catalogues for T32 list the front “strut mount insulator” and bearing as service parts. The rear of the 2015 X‑Trail is a multi‑link setup with separate shocks and coils, so it doesn’t use rear strut mounts in the same sense—just upper shock mounts/bushes.

Up front, the strut mount does more than just cap the strut. It supports vehicle weight, allows the strut to pivot smoothly as the wheels steer, and isolates noise, vibration, and harshness from the body. When healthy, it keeps the steering feel tidy and quiet, and helps maintain correct camber as the suspension moves.

For servicing a 2015 X‑Trail, it’s smart to treat the front strut mounts as wear items—particularly on Aussie and Kiwi roads. They commonly last 80,000–150,000 km, but heavy loads, corrugations, and big potholes can shorten that. Many workshops replace the mounts and bearings whenever fitting new front struts to avoid a second tear‑down and to restore steering smoothness.

Typical signs a front strut mount is on the way out include:

• Clunks or knocks over speed humps and driveway entries
• Notchy, heavy, or “memory” steering at low speeds
• Uneven tyre wear or vague front‑end feel
• Creaks when turning the wheel at a standstill

Replacement tips a good workshop will follow:

• Replace mounts and bearings in pairs, use quality components matched to the T32.
• Use a proper spring compressor, don’t zip the centre nut with an impact gun.
• Observe top mount orientation marks, torque to factory specs.
• Book a wheel alignment after refitting the front struts.
• Inspect the front strut bearings, dust boots, bump stops and sway‑bar links while in there.

If the rear end’s noisy, remember the T32 uses shock mounts/bushes back there, not strut mounts. Those can be renewed independently if they’re creaking or thumping.

Popular questions

Does the rear of a 2015 X‑Trail have strut mounts?
Not in the strict sense. The T32 runs a multi‑link rear with separate shocks and springs, so it uses rear shock upper mounts/bushes rather than strut mounts. If you’re chasing a rear knock, check those shock mounts and the control arm bushes.

How long do front strut mounts last on a 2015 X‑Trail?
Typically 80,000–150,000 km, depending on road conditions and loads. Frequent gravel, corrugations, heavy towing or roof loads can bring that forward. If you’re replacing front struts, doing mounts and bearings at the same time is good value.

Can worn strut mounts affect steering?
Absolutely. Because the front mount houses a bearing for steering rotation, wear can cause notchy or heavy steering, a creak as you turn the wheel, and inconsistent return‑to‑centre. Left too long, it can also contribute to uneven tyre wear and vague handling.
