It is never pleasurable to experience a sound on your car that you don’t know where it comes from. You may be thinking about what to do when you find a reversing gear noise that remains on your Opel Mokka? Any gearbox problem can be critical, but before making sure, it is better to do a few inspections. Our team has written this paper to support you deal with it. First, we will see what the origins and the different gearbox noises can be on Opel Mokka, and second, what are the solutions available to you.
Classical reverse Opel Mokka noises and some tips to protect your gearbox
Why does the reversing of my Opel Mokka make a different noise from my other speeds?
De facto, adding all gears, bearings and pinions into a gearbox is a difficult task. The noise made by the reversing of your Opel Mokka 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 less important than with spur gears implemented 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 car in the revs, you risk to burn your clutch or gnawing at the gearbox pinions. - Never reverse while the car is in motion or vice versa:
Reversing the direction of operation of the gearbox during operation is a very bad practice. Indeed, the pressure you will apply on the gears will be significant and you will develop 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 common if you notice a reverse noise on your Opel Mokka if you shift gear under these conditions.
Different Opel Mokka reversing noises and their triggers
Finally in this section, we will move on to what you are probably most interested in this article, to find out about the origin of reversing noise on Opel Mokka. Here are the 3 typical noises you may be victim of.
I experience a grinding noise when starting in reverse gear
If you experience a grinding noise when you start in reverse with your Opel Mokka, 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 made 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 paper for more details about strut mount noises on Opel Mokka.
An increased reverse knocking noise on Opel MokkaX
If you are subject to a knocking noise when you are in reverse with your Opel Mokka and this noise tends to build up as you gain speed. It is plausible that you are experiencing a serious problem that needs to be fixed very fast before wrecking your entire gearbox. Indeed, 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 car to your technician quickly or read this document about gearbox noise on Opel Mokka for more data.
I find out a noise when I go in reverse
Hearing 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 Opel Mokka reverse gear makes more noise than before, it is plausible that filings have been created and are moving around in it. It is therefore time to empty the box.
