Classical reverse Volkswagen Polo 4 noises and some tips to look after your gearbox
Why does the reversing of my Volkswagen Polo 4 make a different noise from my other speeds?
De facto, adding all gears, bearings and pinions into a gearbox is a difficult process. The sound made by the reversing of your Volkswagen Polo 4 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 strong 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 choice. Indeed, the pressure you will put in on the gears will be enormous and you will produce 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 common if you perceive a reverse noise on your Volkswagen Polo 4 if you shift gear under these conditions.
Different Volkswagen Polo 4 reversing noises and their origins
Finally in this section, we will move on to what you are probably most enthusiastic about in this article, to find out about the source of reversing noise on Volkswagen Polo 4. Here are the 3 typical sounds you may be victim of.
I find out a grinding noise when starting in reverse gear
If you notice a grinding noise when you start in reverse with your Volkswagen Polo 4, 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 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 circumstance, do not hesitate to check this paper for more information about strut mount noises on Volkswagen Polo 4.
An increased reverse knocking noise on Volkswagen Polo 4X
If you are subject to a knocking noise when you are in reverse with your Volkswagen Polo 4 and this noise tends to increase as you gain speed. It is plausible that you are experiencing a serious problem that needs to be fixed right away before destroying 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 very fast. Take your car to your mechanic quickly or check out this article about gearbox noise on Volkswagen Polo 4 for more details.
I acknowledge a noise when I go in reverse
Finding out 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 Volkswagen Polo 4 reverse gear makes more noise than before, it is plausible that filings have been made and are moving around in it. It is therefore time to empty the box.
