Classical reverse Peugeot 4008 noises and some tips to protect your gearbox
Why does the reversing of my Peugeot 4008 make a different noise from my other speeds?
De facto, integrating all gears, bearings and pinions into a gearbox is a difficult process. The noise generated by the reversing of your Peugeot 4008 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 employed 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 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 monumental and you will develop 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 typical if you perceive a reverse noise on your Peugeot 4008 if you shift gear under these conditions.
Several Peugeot 4008 reversing noises and their origins
Finally in this section, we will move on to what you are probably most excited about in this document, to learn about the cause of reversing noise on Peugeot 4008. Here are the 3 typical sounds you may be victim of.
I listen to a grinding noise when starting in reverse gear
If you perceive a grinding noise when you start in reverse with your Peugeot 4008, 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 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 check this document for more information about strut mount noises on Peugeot 4008.
An increased reverse knocking noise on Peugeot 4008X
If you are subject to a knocking noise when you are in reverse with your Peugeot 4008 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 solved 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 very fast. Take your car to your mechanic quickly or check out this article about gearbox noise on Peugeot 4008 for more details.
I perceive a noise when I go in reverse
Experiencing 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 4008 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.
