The shock absorption system is the heart of any car's suspension, and Nissan Bluebird is no exception. Not only the comfort of the ride, but also the safety of driving, especially on high-speed highways or in poor road conditions, directly depends on the condition of the struts. Many owners of this model are faced with the need to replace suspension elements much earlier than planned due to specific operating conditions.
Correct selection and timely replacement shock absorbers allow you to maintain the geometry of the car and extend the life of other chassis components. Ignoring the first signs of a malfunction can lead to critical consequences, such as loss of control of the car during emergency braking. In this article we will look at all the nuances associated with racks for Nissan Bluebird, from diagnostics to installation subtleties.
Bluebird suspension design features
Suspension Nissan Bluebird in different generations (U11, U12, U13, U14) has its own unique engineering solutions. The front part is usually made according to the MacPherson pattern, where shock absorber strut is an integral element of the steering, while at the rear a multi-link system or semi-independent beam is often used. Understanding this architecture is critical for proper parts selection.
A feature of many models is the use gas-filled shock absorbers that provide better rigidity and controllability compared to oil analogues. However, they are more demanding on the quality of the road surface. If you often drive on rough roads, you should pay attention to enhanced modifications or hybrid options.
- 🛠️ Check the suspension type in the technical documentation for your specific year of manufacture.
- 🚗 The rear suspension may have differences in mounting depending on the body version (sedan, station wagon, liftback).
- ⚙️ Consider the presence of anti-roll bars that are attached directly to the racks.
Main signs of shock absorber wear
Determine what racks have worked out their service life, it is possible not only in appearance, but also in the behavior of the car on the road. The appearance of extraneous knocks when driving over bumps is the first sign that requires immediate attention. Often the sound is heard from only one side, indicating a localized problem.
In addition to acoustic signals, pay attention to controllability. If the car begins to “yaw” along the trajectory, and the body rolls heavily in corners, it means shock absorption system no longer copes with vibration damping. Braking distances may increase and the front wheels may begin to bounce during heavy braking.
A visual inspection also provides a lot of information. Oil leaks on the shock absorber body are a sure sign of oil seal failure. Even the slightest leak means that the seal is broken, and gas or oil leaks out, and dirt and moisture gets inside.
⚠️ Attention: Do not confuse the knocking of the struts with the knocking of the stabilizer or bushings. Incorrect diagnosis can lead to replacement of good parts instead of worn ones.
- 👀 Inspect the body for traces of oil, dust and corrosion.
- 📉 Check the condition of the anthers and bumpers - damage to them kills the rack faster.
- 📏 Measure the ground clearance: sagging in one corner indicates a loss of elasticity.
- Knocking on bumps
- Increased roll in corners
- Oil leak
- Increased braking distance
Original or analogue: what to choose for Bluebird?
Choice between original spare parts and high-quality analogues is an eternal dilemma for car owners. For Nissan Bluebird Original struts (Nissan Genuine Parts) offer the perfect balance of comfort and handling designed by factory engineers. However, they are often overpriced and their service life does not always meet expectations under harsh operating conditions.
Analogs from trusted brands can offer better performance for the same money. Japanese and European manufacturers often make stiffer or softer options, allowing you to customize the suspension to suit your preferences. The main thing is to choose trusted manufacturers to avoid fakes.
| Manufacturer | Type | Features | Average price |
|---|---|---|---|
| Nissan (Genuine) | Original | Perfect factory setting, high price | High |
| Kayaba (KYB) | Analogue | Popular choice, excellent availability, different series | Average |
| Sachс | Analogue | European quality, comfortable ride | Medium/High |
| Monroe | Analogue | Reliability, wide range for older models | Average |
Don't skimp on safety-critical details. Cheap Chinese analogues often do not withstand even 10 thousand kilometers, losing their properties. Kayaba Excel-G struts are the most popular choice among Bluebird owners, providing an excellent balance of price and performance for everyday riding. This is a proven solution that suits most drivers.
When purchasing analogues, always check the hologram on the packaging and the presence of protective elements on the shock absorber rod.
Preparation for replacement and necessary tools
Replacement shock absorbers is a task that you can handle yourself if you have the right tools and space. You will need a jack, reliable stands (goats), a set of wrenches and sockets, and a mounting spade. A special spring puller is often required to work with the upper mounts if you are replacing the strut assembly.
Before starting work, the vehicle must be securely secured. Never rely on a jack alone - always use sill stands or side members. Loosen the lug nuts on the wheels before you lift the car, this will make the process much easier.
☑️ Tools for replacing racks
Clean the mounting points from dirt and rust. Use penetrating lubricant 15-20 minutes before you begin removing bolts. If the threads are very stuck, you may need to apply heat, but do this carefully so as not to damage the rubber elements or paint.
Step-by-step instructions for replacing racks
The replacement process begins with lifting the car and removing the wheel. Unscrew the lower bolt securing the shock absorber to the steering knuckle. This often requires significant force, so use a lever from a piece of pipe.
Next, go to the engine compartment. Unscrew the nuts securing the upper support to the body. If you are replacing the entire strut, disconnect it from the body and remove it from the arch. When replacing only the cartridge (internal part), you will need to compress the spring with a special tool.
Installing a new rack is done in the reverse order. It is important to observe the tightening torque of all bolts. The upper nuts are tightened only after the car is lowered to the ground and the wheels are under load, otherwise the support may become distorted.
⚠️ Caution: When using a spring remover, make sure that the springs are compressed evenly on both sides to avoid spring flyout and injury.
- 🔧 Use a torque wrench to accurately tighten the fasteners.
- 🔄 Change stands in pairs on the same axis to maintain balance.
- 🔩 Do not overtighten the rubber bushings, this will lead to their rapid destruction.
What to do if the rod scrolls?
If the shock absorber rod rotates when the nut is unscrewed, use a special wrench to hold the rod or carefully clamp it in a vice through a soft spacer so as not to damage the threads.
Wheel alignment and final checks
After replacing the front struts Nissan Bluebird it is necessary to complete the procedure wheel alignment. Any intervention in the suspension geometry changes the wheel alignment angles. Driving without correction will lead to rapid and uneven tire wear, as well as to the car “pulling” to the side when driving in a straight line.
Before entering the stand, make sure that all bolts are tightened to the correct torque. Notify the technician that the racks have been replaced. Check the operation of the steering - it should be clear, without play or jamming.
Take it for a test drive. Pay attention to how the suspension operates at different speeds. If the knocking noises have disappeared and the car has become more stable, then the work has been done efficiently. Also check for oil leaks on new elements after the first kilometers.
Replacing struts without subsequent wheel alignment can lead to damage to new tires after 1000-2000 kilometers.
Maintenance and extension of suspension life
In order for new racks to last a long time, they need to be looked after. Inspect their condition regularly, especially after off-road trips or in winter, when the roads are sprinkled with reagents. Corrosion and dirt are the main enemies of shock absorbers.
Change boots and bumpers in a timely manner. These inexpensive elements protect the rod from abrasive particles. If the boot is torn, dirt gets onto the seal and it quickly wears out, causing a leak.
- 🧼 Wash the suspension at every general car wash.
- ❄️ In winter, check the elements more often for ice and frozen dirt.
- 🛣️ Avoid sharp impacts on curbs and deep holes at high speed.
Following these simple rules will help you avoid premature replacement and save significant money. Remember that a suspension is a system where all elements are interconnected, and a problem in one part can quickly damage neighboring components.
What are the best racks for Nissan Bluebird U14?
For Nissan Bluebird U14 the most popular are Kayaba Excel-G or KYB Ultra SR struts for those who like a tougher and sportier ride. For comfortable city use, original Nissan struts or Monroe Sensa-Trac shock absorbers are perfect.
Is it possible to change only one rack?
Technically possible, but highly not recommended. Differences in performance between the new and old strut will result in uneven weight distribution, poor handling and increased tire wear. Always replace shock absorbers in pairs on the same axle.
How long are the struts on a Nissan Bluebird?
The average service life of struts is 60-80 thousand kilometers, but this greatly depends on the quality of the roads and driving style. Under Russian road conditions, this period can be reduced to 40-50 thousand kilometers, especially for original parts.
Is a wheel alignment necessary after replacing the rear struts?
If the rear suspension design does not provide for angle adjustment (as is the case with many beam models), then a wheel alignment is not required. However, if you have changed the elements of the multi-link rear suspension or the bolt pattern, checking the wheel alignment will be unnecessary.
