As a supplier of Infiniti Struts, I've seen firsthand how crucial it is to diagnose strut - related vibrations accurately. Vibrations in your Infiniti can be a real pain in the neck and a potential safety hazard. So, let's dig into how you can figure out if the struts are the root cause of those annoying shakes.
Understanding the Basics of Infiniti Struts
Before we jump into diagnosis, it's important to know a bit about what Infiniti struts do. These struts are a key part of your car's suspension system. They help to keep your tires in contact with the road, provide a smooth ride, and absorb the shock from bumps and uneven surfaces. Over time, though, they can wear out, and that's when problems start popping up.
Visual Inspection
The first step in diagnosing vibrations caused by Infiniti struts is a good old - fashioned visual inspection. Park your Infiniti on a flat and level surface and make sure the engine is off.
- Check for Leaks: Walk around your car and look at the struts. If you see any fluid leaking down the side of the strut, that's a big red flag. A leaking strut is likely not functioning properly and could be the source of your vibrations. Leaky struts lose their ability to dampen shocks effectively, which can lead to a bumpy and vibrating ride.
- Look for Damage: Inspect the strut housing for any visible signs of damage, such as dents, cracks, or bends. A damaged strut won't be able to operate as it should, causing irregular movement and vibrations. Also, check the mounting points of the struts. Loose or damaged mounting bolts can lead to instability and vibrations. Make sure all the bolts are tightened to the manufacturer's specifications.
Bounce Test
The bounce test is a simple yet effective way to assess the condition of your Infiniti's struts.
- Stand next to each corner of the car. Push down hard on the fender and then quickly let go. The car should bounce up and then settle back down smoothly. If the car continues to bounce more than a couple of times, it could mean that the struts are worn out. Worn - out struts can't control the movement of the suspension effectively, leading to excessive bouncing and vibrations.
Road Test
One of the best ways to diagnose vibrations is to take your Infiniti for a spin.
- Smooth Roads: Start by driving on a smooth road at a moderate speed. Pay close attention to the steering wheel and the overall feel of the car. If you feel vibrations in the steering wheel, it could indicate a problem with the front struts. Front - end vibrations can also be felt in the seat and floorboard. If you notice these vibrations are more pronounced when going over small bumps or during light braking, it's likely an issue with the struts.
- Bumpy Roads: Drive over some bumpy roads or speed bumps. A well - functioning strut should absorb the shock and provide a relatively smooth ride. If you experience excessive vibrations, harsh impacts, or a "bottoming out" feeling, it's a sign that the struts might be worn or damaged.
Wheel Balance and Alignment
Sometimes, vibrations can be misinterpreted as a strut problem when they're actually due to wheel balance or alignment issues.
- Wheel Balance: Unbalanced wheels can cause vibrations, especially at higher speeds. Have your wheels balanced regularly. If you've already checked the struts and are still experiencing vibrations, an out - of - balance wheel could be the culprit.
- Wheel Alignment: Improper wheel alignment can also lead to vibrations. If your Infiniti pulls to one side or the steering wheel isn't centered when driving straight, it's a good idea to have the alignment checked. Correct alignment ensures that the tires wear evenly and the car rides smoothly.
Diagnostic Tools
If you're still not sure after doing the above checks, there are some diagnostic tools available.


- OBD - II Scanner: An On - Board Diagnostic (OBD - II) scanner can read the error codes from your car's computer system. Some strut - related problems might trigger error codes, which can give you more clues about what's going wrong.
- Vibration Analyzers: These specialized tools can measure the frequency and intensity of the vibrations. They can help you pinpoint the exact source of the vibrations, whether it's the struts or another component.
When to Replace Your Infiniti Struts
If you've determined that the struts are causing the vibrations, it's time to consider replacement. As a general rule, struts should be replaced every 50,000 - 100,000 miles, but this can vary depending on your driving conditions and habits.
- Excessive Wear: If your visual inspection showed significant wear, leaks, or damage, it's a clear sign that the struts need to be replaced.
- Continued Vibrations: Even after trying to fix other potential causes, if the vibrations persist, it's likely that the struts are beyond repair.
