Classical reverse Infiniti Q50 noises and some tips to maintain your gearbox
Why does the reversing of my Infiniti Q50 make a different noise from my other speeds?
De facto, integrating all gears, bearings and pinions into a gearbox is a difficult task. The sound induced by the reversing of your Infiniti Q50 is logical. It can be explained in a fairly simple way. In fact, 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 less important than with spur gears employed 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 practice. In fact, the pressure you will apply on the gears will be monumental and you will develop 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 usual if you listen to a reverse noise on your Infiniti Q50 if you shift gear under these conditions.
Different Infiniti Q50 reversing noises and their causes
Finally in this section, we will move on to what you are probably most curious about in this document, to find out about the cause of reversing noise on Infiniti Q50. Here are the 3 typical sounds you may be victim of.
I experience a grinding noise when starting in reverse gear
If you listen to a grinding noise when you start in reverse with your Infiniti Q50, it may be the engine mounts that are tired. In fact, 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 case, do not hesitate to consult this article for more information about strut mount noises on Infiniti Q50.
An increased reverse knocking noise on Infiniti Q50X
If you are subject to a knocking noise when you are in reverse with your Infiniti Q50 and this noise tends to amplify as you gain speed. It is plausible that you are going through a serious problem that needs to be resolved quickly before wrecking your entire gearbox. In fact, an intensifying rattling noise means that the gears are damaged. If they are, debris will propagate to the rest of the box and damage other gears in short order. Take your vehicle to your auto mechanic quickly or browse this document about gearbox noise on Infiniti Q50 for more data.
I acknowledge a noise when I go in reverse
Hearing a noise when you shift into reverse is normal and relating to the gears and sprockets used in the gearbox. If, on the other hand, you have the feeling that your Infiniti Q50 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.
