Classical reverse Peugeot 308 noises and some tips to preserve your gearbox
Why does the reversing of my Peugeot 308 make a different noise from my other speeds?
De facto, integrating all gears, bearings and pinions into a gearbox is a difficult action. The noise induced by the reversing of your Peugeot 308 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:
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 practice. Indeed, the pressure you will exert 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 usual if you hear a reverse noise on your Peugeot 308 if you shift gear under these conditions.
Several Peugeot 308 reversing noises and their causes
Finally in this section, we will move on to what you are probably most interested in this article, to learn about the origin of reversing noise on Peugeot 308. Here are the 3 typical sounds you may be victim of.
I notice a grinding noise when starting in reverse gear
If you find out a grinding noise when you start in reverse with your Peugeot 308, 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 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.

An increased reverse knocking noise on Peugeot 308X
If you are subject to a knocking noise when you are in reverse with your Peugeot 308 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 fairly quickly before wrecking 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.

I discover 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 Peugeot 308 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.
