It is never enjoyable to notice a sound on your vehicle that you don’t know where it comes from. You may be questioning what to do when you identify a reversing gear noise that persists on your Infiniti G? Any gearbox trouble can be critical, but before making sure, it is better to do a few inspections. Our team has written this content page to support you solve it. First, we will see what the sources and the different gearbox noises can be on Infiniti G, and second, what are the solutions available to you.
Classical reverse Infiniti G noises and some tips to preserve your gearbox
Why does the reversing of my Infiniti G make a different noise from my other speeds?
De facto, adding all gears, bearings and pinions into a gearbox is a difficult exercise. The sound caused by the reversing of your Infiniti G is logical. It can be explained in a fairly simple way. Indeed, the gears used for conventional speeds (1st to 5th or 6th) are so-called “helical” gears (oblique gears) . The use of such a pinion makes the noise caused by the gears much less important than with spur gears used for the reverse gear.
Tips to reduce wear on your clutch and gearbox
- Don’t give a big boost:
In fact, if you kick the throttle hard when you are in reverse or when you put the vehicle in the revs, you risk to burn your clutch or gnawing at the gearbox pinions. - Never reverse while the vehicle is in motion or vice versa:
Reversing the direction of operation of the gearbox during operation is a very bad choice. Indeed, the pressure you will exert on the gears will be monumental and you will create a premature wear and tear of the gears. You can even destroy the gears of your gearbox at speed by doing so. It will therefore be completely common if you experience a reverse noise on your Infiniti G if you shift gear under these conditions.
Several Infiniti G reversing noises and their causes
Finally in this section, we will move on to what you are probably most curious about in this page, to find out about the source of reversing noise on Infiniti G. Here are the 3 typical sounds you may be victim of.
I hear a grinding noise when starting in reverse gear
If you notice a grinding noise when you start in reverse with your Infiniti G, it may be the engine mounts that are tired. Indeed, when the engine is in reverse gear, due to the pinions we saw above the vibrations generated by the gearbox are higher and it is therefore plausible that due to their wear the silentblocks no longer absorb the engine vibrations well. In this situation, do not hesitate to consult this article for more information about strut mount noises on Infiniti G.
An increased reverse knocking noise on Infiniti GX
If you are subject to a knocking noise when you are in reverse with your Infiniti G and this noise tends to amplify as you gain speed. It is plausible that you are experiencing a serious trouble that needs to be resolved rather quickly before ruining your entire gearbox. Indeed, an intensifying rattling noise means that the gears are damaged. If they are, debris will spread to the rest of the box and damage other gears in short order. Take your vehicle to your mechanic quickly or read this document about gearbox noise on Infiniti G for more details.
I discover a noise when I go in reverse
Finding out a noise when you shift into reverse is normal and connected to the gears and sprockets used in the gearbox. If, on the other hand, you have the feeling that your Infiniti G reverse gear makes more noise than before, it is plausible that filings have been produced and are moving around in it. It is therefore time to empty the box.
