It is never pleasurable to perceive a sound on your car that you don’t know where it comes from. You may be wondering what to do when you find a reversing gear noise that continues on your Mazda 5? Any gearbox trouble can be serious, but before making sure, it is better to do a few investigations. Our team has written this article to support you solve it. First, we will see what the origins and the different gearbox noises can be on Mazda 5, and second, what are the solutions available to you.
Classical reverse Mazda 5 noises and some tips to look after your gearbox
Why does the reversing of my Mazda 5 make a different noise from my other speeds?
De facto, integrating all gears, bearings and pinions into a gearbox is a difficult process. The sound induced by the reversing of your Mazda 5 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 employed for the reverse gear.
Tips to limit 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 idea. Indeed, the pressure you will apply on the gears will be enormous and you will make 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 experience a reverse noise on your Mazda 5 if you shift gear under these conditions.
Several Mazda 5 reversing noises and their causes
Finally in this section, we will move on to what you are probably most interested in this document, to learn about the cause of reversing noise on Mazda 5. Here are the 3 typical sounds you may be victim of.
I experience a grinding noise when starting in reverse gear
If you perceive a grinding noise when you start in reverse with your Mazda 5, 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 situation, do not hesitate to read this content for more details about strut mount noises on Mazda 5.
An increased reverse knocking noise on Mazda 5X
If you are subject to a knocking noise when you are in reverse with your Mazda 5 and this noise tends to build up as you gain speed. It is plausible that you are confronting a serious trouble that needs to be fixed 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 car to your auto mechanic quickly or browse this content about gearbox noise on Mazda 5 for more information.
I acknowledge a noise when I go in reverse
Hearing 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 Mazda 5 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.
