Strut Mount for 2009 Nissan Pathfinder SE Off-Road

The strut mount is where a quarter of your Nissan Pathfinder's weight enters the body, and on a steering corner it is also where the strut rotates.

Doing both of those through one component is why it wears out and why it produces such a varied set of complaints.

Nissan Pathfinder Strut Mount or Torque Strut Mount

Two completely different parts share most of a name, and sorting that out first saves ordering the wrong one.

A strut mount, also called a strut top mount or upper strut mount, sits at the top of a suspension strut where it meets the body. The rubber element inside is listed separately as a strut mount bushing on applications where it can be replaced on its own. It carries vertical load, isolates the cabin and on a front corner contains a bearing.

A torque strut mount is an engine mount. It is the arm, sometimes called a dogbone or torque rod, that stops the engine rotating under load on a transverse layout.

The two are nowhere near each other on the vehicle and they have nothing in common beyond the word strut.

If the complaint is a knock over bumps or vague steering, it is the suspension mount. If it is a clunk on gear changes or when getting on the throttle, it is the engine part.

What a Nissan Pathfinder Strut Mount Has to Do

Three jobs at once, which is unusual for one component.

Load carrying is the first of the three. The strut pushes up into the body through the mount, and on a front corner that is a significant share of the vehicle's weight present at all times.

Rotation is the second, on a steering corner. The entire strut assembly turns as the wheel steers, so the mount has to allow that movement while allowing nothing else.

Isolation is the third job the mount handles. Everything the damper transmits arrives at the body here, so the mount is the final filter between the road and the cabin.

A design optimized for any one of those compromises the other two, which is why the factory part sits in the middle and why it is a known service item rather than a lifetime component.

The Nissan Pathfinder Strut Mount Bearing

On a front corner the bearing is a separate component inside the mount, and it fails independently of the rubber around it.

It is a thrust bearing, carrying vertical load while allowing rotation. That is a harder duty than either task alone and it is why the bearing is usually what gives up first.

Water is usually what finishes a strut mount bearing off. Once the seal degrades, grease washes out, corrosion starts and the rolling elements pit.

The driver feels that as steering that catches or steps through a turn, a creak at low speed while turning, or a wheel that will not return to center on its own.

Because the bushing can be sound while the bearing is finished, a mount can produce steering complaints with no knocking over bumps at all.

Some applications supply the bearing separately and others only as part of a complete mount, which is worth checking before ordering.

Nissan Pathfinder Strut Mount Noise and What It Means

The noises are distinctive enough to separate once you know what to listen for.

A creak or groan when turning the wheel at a standstill is the bearing. Nothing else in that area rotates, so the diagnosis is close to certain.

A knock or clunk over bumps that does not change with steering position points at the bushing, the bump stop or something else at the top of the strut.

A clunk that only appears when turning and crossing a bump together can be the mount and can equally be a sway bar link, so that one needs a closer look.

Increased road noise and vibration with no knock at all is the early symptom, where the rubber has hardened but not yet separated.

Have someone turn the wheel lock to lock while you listen at the strut tower. That separates the bearing from everything else in about thirty seconds.

Bad Nissan Pathfinder Strut Mount Symptoms

• A knock or clunk from the top of the strut over bumps
• Creaking or groaning when steering at low speed
• Steering that catches or does not self center
• More road noise and vibration through the body
• Visible cracking or separation in the rubber
• The strut top visibly moving within the mount when levered
• Alignment that will not hold its settings between services
• Uneven tire wear with no other fault to explain it

Alignment drift is the one people miss. The mount is the upper point of the steering geometry, so a mount with play means the camber and caster set on the rack are not what the car has under load.

Front and Rear Mounts Are Different Parts

Where a vehicle runs struts at both ends, the two positions live very different lives.

Front mounts carry more weight, take braking loads and rotate with the steering. The bearing is present only here, and it is the component that usually dictates when the mount gets replaced.

Rear mounts carry less, take no steering load and contain no bearing. They fail through the rubber perishing rather than through anything mechanical, so the symptom is a knock rather than a steering complaint.

That difference means front mounts commonly need replacing while the rears are still serviceable, and replacing all four when only the fronts have failed is usually unnecessary.

Assess each end of the car on its own condition. A noise from the front tells you nothing about what is happening at the back.

Loaded and Modified Vehicles

Both ends of the modification spectrum work these harder than standard.

A vehicle carrying permanent front weight, a bull bar, winch or heavy accessories, compresses the mount further on every input and shortens its life accordingly.

Lowering changes the angle the strut sits at, so the mount carries load in a slightly different direction to the one it was designed around, and the suspension spends more time near full compression.

Track use adds impact loading on top of that. Curbs and high speed bumps put shock through the single point connecting suspension to body.

Heavy duty mounts exist for those situations, using firmer bushing material and stronger construction to cope with the extra load and the altered geometry.

On a vehicle that has been modified at all, specifying the mount around the finished vehicle rather than the original avoids replacing it again inside two years.

Universal and Sized Mounts

Most strut mounts are application specific, and some positions are listed by dimension instead.

Application specific mounts match the stud pattern, the stud length, the bearing diameter and the height required to locate the strut where the manufacturer intended.

Universal or sized mounts turn up on older platforms, custom installations and anything running aftermarket struts that did not come with mounts.

Where a sized part is being used, the height is the dimension to get right. A mount that sits the strut higher or lower than standard changes ride height and the geometry with it.

Check the stud spacing and the bearing bore against what you have rather than matching by appearance, since mounts that look similar frequently are not.

Nissan Pathfinder Strut Mount Replacement Cost

The part is modest and the labor is where the figure comes from.

The strut has to come out, and unless the whole assembly is being replaced, the spring has to be released. That means spring compressors and the care that goes with them.

Compressed coil springs hold serious stored energy, and releasing one unexpectedly causes severe injury. That risk is the reason most people pay for this job rather than doing it.

A pre assembled strut includes the mount, bearing, bump stop and boot along with the damper and spring, which removes the spring work entirely and often costs less once labor is counted.

An alignment afterward is required on a front corner, since the upper geometry point has been disturbed.

Doing both sides at once is standard, since the access is identical and matched behavior across the axle matters.

What Goes In With It

The access is the expensive part, so a few items are worth doing at the same time.

A perished bump stop inside the assembly leaves the suspension hitting metal at full compression, and it ages on the same timeline as the mount.

The dust boot protects the damper shaft from grit, which is what destroys the shaft seal and starts a leak.

The coil spring insulator sits between the spring and the mount, and a flattened one makes noise that gets blamed on the new part.

The damper itself is worth assessing honestly too. Doing the mount now and the strut in six months means paying the same labor twice.

Find Strut Mounts for Your Nissan Pathfinder

Select your Nissan Pathfinder to see the strut mounts available for it in front and rear fitments. If the steering creaks at low speed, check the bearing first, and if the alignment will not hold, check for play at the top of the strut before adjusting anything.
