Crossover stability and handling Nissan Murano largely depend on the condition of the anti-roll bar elements. This design detail links the suspension arms and the body, preventing strong body roll when cornering. Over time, the rubber bushings that provide damping and free rotation of the rod lose their properties due to constant vibration, exposure to reagents and temperature changes.
Ignoring wear symptoms can lead not only to an unpleasant knocking sound when driving over bumps, but also to accelerated failure of other components of the chassis. On Nissan Murano second and third generation, this repair is one of the most common routine maintenance procedures. A competent approach to replacement allows you to return the car to its factory smooth ride and precise handling without extra costs in a car service center.
How to recognize worn stabilizer bushings on a Murano
The main indicator of the problem is a characteristic knocking or squeaking noise that occurs when driving over small bumps, speed bumps or potholes. The sound usually comes from the front or rear suspension and gets louder when driving on bad roads. It is important to distinguish this knock from the sound of worn silent blocks of levers or ball joints, since diagnostics require careful listening to the operation of the components.
In addition to acoustic signals, the driver may notice a deterioration in handling. The car begins to behave less predictably when cornering, and excessive rolliness appears. In some cases, play in the steering wheel may occur, which cannot be eliminated by adjusting the steering rack. This is due to the fact that a broken bushing does not hold the stabilizer in the correct position, disrupting the geometry of the suspension.
If you conduct a visual inspection, you can often see deep cracks, tears, or complete delamination of the rubber from the metal insert on old parts. Sometimes the rubber simply dries out and crumbles, turning into dust. In this case, the stabilizer begins to hit the metal elements of the brackets, creating a metallic clang.

Selection of quality spare parts: Original or analogue?
When choosing bushings for Nissan Murano owners are often faced with a dilemma: install original parts or trust proven analogues. Original from Nissan usually has a high price, but guarantees an exact match to the geometry and composition of the rubber compound. However, factory bushings are not always the best choice in terms of price-quality ratio, as their service life may be lower with some specialized brands.
The market offers many manufacturers specializing in chassis. Level brands Febi Bilstein, Corteco or 555 They often offer products made from more wear-resistant rubber or polyurethane. Polyurethane bushings last much longer than rubber bushings, but they are stiffer, which can slightly reduce comfort when driving on bad roads. The choice depends on your priorities: maximum comfort or durability.
It is important to pay attention to the packaging. Some analogues are sold complete with clamps and lubricant, while original spare parts often require the purchase of fasteners separately. Lack of lubrication can cause the new bushing to start squeaking after just a couple of weeks of use.
- 💎 Original (Nissan) - high price, ideal geometry, average durability
- 🛠 High-quality analogues (Febi, Lemforder) — good tires, affordable price, reliable fasteners
- 🚀 Polyurethane (Safetor, Powerflex) — maximum resource, increased suspension rigidity
- Durability and resource
- Comfort and smooth ride
- Spare part price

Tools and preparation for replacement
To carry out work on replacing bushings with Nissan Murano You will need a standard set of tools that most car enthusiasts have. You will need ring wrenches, a ratchet handle with an extension and a 14 or 17 mm socket (depending on the year of manufacture and generation of the car). A spudger or large screwdriver for loosening the brackets will also be useful.
If you are planning to replace the rear bushings, then you cannot do without a jack and supports. The car must be securely fixed, since the suspension is under load. It is recommended to use wheel chocks that remain on the ground. Before starting work, be sure to read Repair manual for your specific model to find out the exact bolt size and tightening torques.

Step-by-step instructions for replacing bushings
The replacement process begins with lifting the car and removing the wheels to provide access to the suspension elements. If the front bushing is changed, it is often necessary to loosen the attachment of the stabilizer to the body. Brackets on Nissan Murano can be screwed with bolts that stick over time, so it is better to pre-treat them with a penetrating lubricant like WD-40 or analogue.
The next step is removing the old bushings. To do this, you need to release the stabilizer from the mount. If the bushings are stuck, they will have to be cut with a knife or grinder, since it is almost impossible to remove them intact. Be careful not to damage the stabilizer itself, as replacing it will cost significantly more.
☑️ Preparation for replacement
After removing the old elements, it is necessary to thoroughly clean the seats from dirt and rust. A layer of special lubricant is applied to the new bushing, which does not destroy the rubber. The stabilizer is installed in place, and the bushing is put on the rod. It is important to check that the bushing is level and that the mounting bolts are tightened without distortion.
Features of replacement on different generations of Murano
On the first generation (Z50), access to the front hubs is difficult due to engine protection. On the second (Z51) and third (Z52) generations, the suspension design has changed and the bushings are often mounted at the top, making work easier. The rear bushings on all models are changed after removing the wheels and loosening the rear beam arms.
Common mistakes and how to avoid them
One of the most common mistakes is trying to tighten the bushing without lubrication. This causes the rubber to twist or tear when the bolts are tightened. Lubrication is also necessary so that the stabilizer can rotate inside the bushing during suspension operation, otherwise an unpleasant squeak will appear. Use only special compounds intended for rubber products.
Another mistake is insufficient tightening of the mounting bolts. The bushing may begin to “walk” inside the bracket, which will cause play and rapid wear of the new parts. On the other hand, excessive force may deform the bracket body or damage the bushing itself. Observe the recommended tightening torques specified in the technical documentation.
Before installing new bushings, be sure to check the condition of the brackets themselves. If the metal is bent or the thread is broken, installing new rubber bands does not make sense - they will fail instantly.
⚠️ Attention: Do not tighten the hub bolts until the vehicle is lowered to the ground and the wheels are loaded with the weight of the vehicle. Otherwise, you will block the rubber element, which will lead to its rapid destruction when moving.
Comparative table of material resource
Understanding the differences in materials will help you make informed choices when purchasing parts. Standard rubber provides comfort, but quickly loses elasticity. Polyurethane can withstand heavy loads, but transmits more vibrations to the body. The table below shows the average resource indicators when used in urban environments.
| Bushing material | Average resource (km) | Comfort | Hardness | Price |
|---|---|---|---|---|
| Factory tires | 30 000 - 50 000 | High | Low | Average |
| High-quality tires (analogue) | 40 000 - 60 000 | High | Average | Low |
| Polyurethane | 80 000 - 120 000 | Medium | High | High |
| Low quality rubber | 10 000 - 20 000 | Low | Low | Very low |
Technical nuances and diagnostic features
When diagnosing the condition of the suspension on Nissan Murano It is important to consider that knocking can be caused not only by bushings, but also by stretched stabilizer struts (links). Links often fail before bushings, and replacing some without checking others may not give the desired result. It is recommended to check the entire stabilizer assembly.
On some versions of the crossover, access to the rear hubs is complicated by the presence of an exhaust system and heat shields. Sometimes it is necessary to temporarily remove part of the exhaust pipe to gain normal access to the brackets. This is a labor-intensive process that requires patience and precision.
⚠️ Attention: If you notice that the stabilizer rotates along with the bushing when moving, this means that the lubricant inside has completely dried out or the bushing is destroyed. Operating the vehicle in this condition is prohibited, as this leads to loss of stability.
For accurate diagnosis, you can use the suspension rocking method. Raise the wheel with a jack and, shaking it with your hands, listen to sounds in the area of the stabilizer brackets. Any clicking or knocking noises indicate the need for repair.
Repair results and quality control
After completing the work on replacing the bushings, it is necessary to carry out a control trip. Pay attention to the absence of extraneous sounds when driving over bumps and the behavior of the car when cornering. If the knocking noise persists, perhaps the problem is not in the bushings, but in other suspension elements, such as silent blocks or ball joints.
Regularly checking the condition of the stabilizer will avoid costly repairs in the future. Timely replacement of bushings Nissan Murano prevents destruction of suspension arms and brackets, which are much more expensive than rubber elements.

How often do you need to change stabilizer bushings on a Nissan Murano?
On average, the service life of bushings ranges from 40 to 60 thousand kilometers, but this depends on the quality of the roads and driving style. On polyurethane bushings, the service life can reach 100 thousand km or more.
Is it possible to change stabilizer bushings without removing the stabilizer?
This is possible on many Nissan Murano models. It is enough to loosen the brackets and lower the stabilizer a little to pull out the old bushing and put on the new one. However, some generations require complete removal for convenience.
What is the best lubricant for stabilizer bushings?
Use special silicone lubricant for rubber products. Do not use lithium grease or WD-40 as a permanent lubricant as they may attack the rubber or polyurethane structure.
What happens if you drive with broken stabilizer bushings?
This will lead to knocking, poor handling and increased roll when cornering. In the long term, this can cause accelerated wear of the levers, silent blocks, and even deformation of the mounting brackets.
