Suspension life on budget sedans often becomes a stumbling block for owners, especially on our roads. When you feel like Nissan Almera has become less stable in turns or a knocking noise has appeared on small bumps, the problem often lies in the front shock absorbers. Their wear affects not only comfort, but also critical safety parameters such as braking distance and handling.
Many car owners put off visiting a service station, believing that knocking is simply a feature of operation. However, ignoring problems with shock-absorbing support or the strut itself can lead to the destruction of other suspension units. In this article, we will analyze in detail how to independently diagnose the fault and perform a high-quality replacement of the front struts, saving on service costs.
Symptoms of wear and diagnostics of suspension
You can determine the need to replace the front struts even before visiting the garage, simply by analyzing the behavior of the car. If, when passing speed bumps, you hear dull impacts, and the body continues to sway after passing the bump, this is the first signal of a loss of damping properties. It is also worth paying attention to uneven wear of the rubber, especially if the tread has worn off along the edges or βbumpsβ have formed.
A visual inspection can provide even more information. Inspect glass rack and the shock absorber body itself for oil leaks. A dry case does not always mean serviceability, but obvious traces of oil are a guaranteed sign of failure o-rings and stock. Don't forget to check the condition of the boot and bump stop, as their destruction often occurs earlier than the failure of the shock absorber itself.
- π Strong knocking or squeaking noise when driving over bumps at low speed.
- π§ Visible oil leaks on the shock absorber body or on the inside of the wheel.
- π The car pulls to the side when braking or driving in a straight line.
- π Increased braking distance and βdivingβ of the nose of the car during sudden braking.
β οΈ Attention: If you notice that the car rolls heavily in turns or βnodsβ when braking, using such a suspension is unacceptable. This creates an emergency situation and can lead to loss of control at high speed.
Selection of spare parts: original or analogue
When preparing for a renovation, you are faced with the question: what to choose? Original racks from Nissan They usually have a high resource and excellent performance, but their price can be too high. Many owners Almera they prefer proven analogues that offer the best value for money, especially if you do not plan to drive at top speeds.
There are many manufacturers on the market specializing in suspension. Brands like Kayaba, Sachs or Monroe have proven themselves as reliable suppliers. It is important to understand that the rack is a complex mechanism, and cheap Chinese fakes may not withstand thousands of kilometers. Saving on spare parts here often leads to double the cost of repeated repairs.
| Brand | Features | Recommendation |
|---|---|---|
| Kayaba (KYB) | Japanese quality, a bit harsh | The best choice for the city |
| Sachs | Comfort, smooth ride | For a quiet ride and track |
| Monroe | Good resource, average price | Balance of price and quality |
| Original Nissan | Ideal geometry, high price | If the budget is not limited |
β οΈ Attention: When purchasing analogues, be sure to check the catalog numbers. On Nissan Almera Different generations (G15 and restyling) racks may differ in the length of the rod and the fastening of the lower bracket. An error in selection will lead to impossibility of installation or rapid failure.
- Original from dealer
- High-quality analogue (Kayaba/Sachs)
- Budget option
- I buy used in good condition
Necessary tools and preparation
Replacing front struts is a job that requires a serious approach and the availability of special tools. You will need a jack and reliable stands for the body, since working under the car with only a jack is strictly prohibited. Also a critical tool is a spring puller. Without it, disassembling the rack becomes an extreme risk of injury or broken parts.
From hand tools, prepare a set of sockets, ratchets and extensions. To unscrew the shock absorber rod mounting nut, you often need a 6 mm hex and a 19 or 27 mm wrench (depending on the generation). Don't forget to use WD-40 or a similar penetrating lubricant, as suspension bolts often become caked with salt and dirt.
- π§ Hydraulic jack and a pair of reliable stands (travelers).
- π© Spring puller (required! Manual spring puller is dangerous).
- π¨ Hammer and pry bar for knocking out the fingers of the levers.
- ποΈ A set of sockets, including cap sockets, and a ratchet wrench.
Before starting work, be sure to treat all bolted joints with penetrating lubricant and leave for 10-15 minutes. This will make unscrewing them much easier, especially if the car has not been serviced recently.
Step-by-step instructions for dismantling and installation
The replacement process begins with lifting the car and removing the wheel. Unscrew the nut securing the upper shock absorber rod, holding the rod itself with a hexagon. Then disconnect the strut from the steering knuckle: to do this, unscrew the lower bolts and, if necessary, release the steering tip. Use a pry bar to push the stand down.
The removed stand must be moved to a workbench. This is where the most important part of the work occurs - transferring the upper support and spring to the new shock absorber. Never loosen a shock absorber rod nut without a pre-compressed spring.. Install the spring puller, squeezing them evenly on both sides, then unscrew the rod nut and reassemble the assembly.
βοΈ Preparing the rack for installation
Installation of the assembled rack is carried out in the reverse order. Insert the upper part into the body glass, aligning the mounting bolts with the holes in the lever. Tighten all bolts to the recommended torque. It is important not to tighten the bolts attaching to the lever by weight - lower the car so that the wheels touch the ground, and only then make the final tightening.
β οΈ Attention: When using a spring puller, make sure it grips the coils securely and does not slip. Improper handling of compressed springs can cause them to shoot out, which can be fatal.
Features of working with the upper support
Often the problem is not in the shock absorber itself, but in a jammed upper mount. If you replace the struts, it is highly recommended that you also replace the support bearings, otherwise the knocking noise will remain, even with new shock absorbers.
Features of wheel alignment adjustment
After replacing the front struts with Nissan Almera It is necessary to undergo a wheel alignment procedure. When removing and installing the strut, the factory wheel alignment angles are violated, which cannot be adjusted by eye. Ignoring this step will lead to rapid wear of the tires and unstable movement of the car.
On many models Almera Camber adjustment is carried out through an eccentric on the lower cup of the strut or through adjusting bolts on the arms. On some versions, it may be necessary to replace the camber bolts with adjustable ones if the standard ones do not provide the required range. The technician at the stand must set the angles within factory tolerances.
- π Toe angles must be set first, as they affect directional stability.
- βοΈ Front wheel camber on Almera usually not regulated regularly, but verification is required.
- π The crosspiece (caster angle) should also be checked as it affects the return of the steering wheel to center.
Adjusting the wheel alignment after replacing struts is not a recommendation, but a mandatory requirement to preserve tire life and control safety.
Common replacement mistakes and how to avoid them
One of the most common mistakes is trying to skimp on upper supports and bearings. If you are changing shock absorbers, old supports with play or soured bearings will negate the entire effect of the repair. Knocks and squeaks may remain even if the new struts are perfect. Always change the assembly or change the supports separately, but do not spare money on these consumables.
Another mistake is not tightening the bolts correctly. Many owners over-tighten the shock absorber rod nut, which can lead to stripped threads or deformation of the rod. Use a torque wrench and check your manual. Also, do not overtighten the mounting bolts to the steering knuckle before the wheels touch the ground - this will create tension in the rubber silent blocks.
Sometimes craftsmen forget to install new boots and bumpers. Old elements often tear or lose elasticity. Without boot protection, the shock absorber rod will quickly be scratched, which will lead to loss of oil and failure of the unit. This is a small thing that is inexpensive, but extends the life of new spare parts by years.
β οΈ Warning: Do not attempt to use a hammer to knock out the pins of the steering knuckles or levers. Impacts to the threaded part may damage the threads and the part will have to be replaced. Use a special puller.
FAQ: Frequently asked questions from car owners
Is it possible to change only one front strut?
Technically this is possible, but it is highly not recommended. Shock absorbers wear out synchronously. If one rack fails, the second is most likely in a similar condition. Installing a new strut on one side will create an imbalance in the suspension, which will worsen handling and increase tire wear. It is better to change the racks in pairs.
How long does it take to replace struts?
For an experienced craftsman, replacing two front struts with moving the supports takes about 1.5β2 hours. If you are doing this for the first time and also changing the support bearings, allow 3-4 hours of work. Do not forget that after this it will take time for wheel alignment.
Do I need to change springs when replacing struts?
If the springs do not show signs of corrosion, cracks or subsidence, they can be left. However, on cars with mileage of more than 100-150 thousand kilometers, springs often lose elasticity. It is recommended to visually check their condition and, if in doubt, install new springs along with the struts.
What is the tightening torque for the shock absorber rod nut?
The tightening torque depends on the specific modification Nissan Almera, but usually it is between 20 and 30 Nm. The exact value is always indicated in the car's service book. Over-tightening can break the thread, and under-tightening will lead to play and knocking in the upper support.
Is it possible to drive without a boot on the stand?
Strongly not recommended. The boot protects the shock absorber rod from dirt, dust and moisture. Without it, the rod will quickly be scratched, the seal will lose its tightness, and oil will begin to leak out. This will lead to rapid failure of the shock absorber, even if it is new.
