It is never enjoyable to experience a sound on your automobile that you don’t know where it comes from. You may be thinking about what to do when you detect a reversing gear noise that lasts on your Nissan NV? Any gearbox issue can be serious, but before making sure, it is better to do a few investigations. Our team has created this paper to help you solve it. First, we will see what the origins and the different gearbox noises can be on Nissan NV, and second, what are the solutions available to you.
Classical reverse Nissan NV noises and some tips to protect your gearbox
Why does the reversing of my Nissan NV make a different noise from my other speeds?
De facto, integrating all gears, bearings and pinions into a gearbox is a difficult task. The noise made by the reversing of your Nissan NV 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 more quiet 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 automobile in the revs, you risk to burn your clutch or gnawing at the gearbox pinions. - Never reverse while the automobile is in motion or vice versa:
Reversing the direction of operation of the gearbox during operation is a very bad idea. Indeed, the pressure you will apply on the gears will be significant and you will generate a premature wear and tear of the gears. You can even break the gears of your gearbox at speed by doing so. It will therefore be completely usual if you hear a reverse noise on your Nissan NV if you shift gear under these conditions.
Several Nissan NV reversing noises and their triggers
Finally in this section, we will move on to what you are probably most curious about in this page, to find out about the cause of reversing noise on Nissan NV. Here are the 3 typical noises you may be victim of.
I notice a grinding noise when starting in reverse gear
If you experience a grinding noise when you start in reverse with your Nissan NV, 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 possible that due to their wear the silentblocks no longer absorb the engine vibrations well. In this case, do not hesitate to consult this document for more details about strut mount noises on Nissan NV.
An increased reverse knocking noise on Nissan NVX
If you are subject to a knocking noise when you are in reverse with your Nissan NV and this noise tends to build up as you gain speed. It is possible that you are experiencing a serious issue that needs to be resolved fairly quickly before destroying your entire gearbox. Indeed, an intensifying rattling noise means that the gears are damaged. If they are, debris will disperse to the rest of the box and damage other gears quickly. Take your automobile to your auto mechanic quickly or read this content about gearbox noise on Nissan NV for more information.
I acknowledge a noise when I go in reverse
Finding out a noise when you shift into reverse is normal and related to the gears and sprockets used in the gearbox. If, on the other hand, you have the feeling that your Nissan NV reverse gear makes more noise than before, it is possible that filings have been created and are moving around in it. It is therefore time to empty the box.
