Infiniti Q45 Struts
Identifying Problems with Infiniti Q45 Struts
Driving a luxury car such as the Infiniti Q45 will not offer much comfort if the suspension system is not in its optimal condition. The struts are one of the most crucial components of any car's suspension system, because they maintain a constant vehicle height, keep a balanced handling, absorb sudden shocks, etc. Driving with failing struts is a huge safety hazard that can result in dangerous accidents. Here is a list of signs indicating that there is something wrong with your Infiniti Q45 struts. This will help you identify the problems early on so you will be able to prevent any untoward incident.
Harsh jolts and clanking noises
Observe how your car performs when driving over speed bumps at around 5 mph. If it delivers harsh jolts and clanking noises, the struts may have lost their dampening effects. This causes the car to bottom out, allowing enough collapse that takes the frame to make metal-to-metal contacts. To confirm this problem without the help of a professional auto mechanic, you can use a tape measure to determine the distances between the wheel wells and the ground. Make sure all tires have the same pressure before starting this test. If the side to side measurements on the front and the rear have a deviation of more than 1/2 inch, the struts have lost their ride height. This might be due to weakened springs.
Park your Q45 on flat ground and execute a "bounce test" by pushing down one corner at a time. Check if the suspension compresses firmly, rises back up immediately, and then stops. If this is your car's case, the struts are still in good shape. But if the corner is quite easy to push down, and it bounces back up a couple of times before it stops, then you need to get new ones.
Tilts during turns
Find out how your car is when turning a corner. If there is much rollover or tilting to one side, the struts are shot and you will need replacements. This may be caused by leaks in shock body brought about by damaged seals. Check the strut assembly for any traces of oil and grime buildup.
