It is never enjoyable to notice a sound on your vehicle that you don’t know where it comes from. You may be thinking about what to do when you identify a reversing gear noise that lasts on your Subaru Impreza? Any gearbox problem can be severe, but before making sure, it is better to do a few inspections. Our team has written this content page to support you eliminate it. First, we will see what the sources and the different gearbox noises can be on Subaru Impreza, and second, what are the solutions available to you.
Classical reverse Subaru Impreza noises and some tips to preserve your gearbox
Why does the reversing of my Subaru Impreza 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 induced by the reversing of your Subaru Impreza 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:
Certainly, 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 idea. Indeed, the pressure you will put in on the gears will be monumental and you will create 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 perceive a reverse noise on your Subaru Impreza if you shift gear under these conditions.
Several Subaru Impreza reversing noises and their causes
Finally in this section, we will move on to what you are probably most excited about in this content, to learn about the source of reversing noise on Subaru Impreza. 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 Subaru Impreza, it may be the engine mounts that are tired. Certainly, when the engine is in reverse gear, due to the pinions we saw above the vibrations produced 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 Subaru Impreza.
An increased reverse knocking noise on Subaru ImprezaX
If you are subject to a knocking noise when you are in reverse with your Subaru Impreza and this noise tends to build up as you gain speed. It is plausible that you are going through a serious problem that needs to be fixed fairly quickly 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 before long. Take your vehicle to your repair shop quickly or browse this article about gearbox noise on Subaru Impreza for more details.
I find out a noise when I go in reverse
Listening 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 Subaru Impreza 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.
