Classical reverse Mercedes Classe C 2 noises and some tips to protect your gearbox
Why does the reversing of my Mercedes Classe C 2 make a different noise from my other speeds?
De facto, adding all gears, bearings and pinions into a gearbox is a difficult process. The noise generated by the reversing of your Mercedes Classe C 2 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 important 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 automobile in the revs, you risk to burn your clutch or gnawing at the gearbox pinions. - Never reverse while the automobile 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 typical if you perceive a reverse noise on your Mercedes Classe C 2 if you shift gear under these conditions.

Finally in this section, we will move on to what you are probably most interested in this document, to find out about the cause of reversing noise on Mercedes Classe C 2. Here are the 3 typical noises you may be victim of.
I notice a grinding noise when starting in reverse gear
If you experience a grinding noise when you start in reverse with your Mercedes Classe C 2, 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. In this case, do not hesitate to browse this document for more information about strut mount noises on Mercedes Classe C 2.
An increased reverse knocking noise on Mercedes Classe C 2X
If you are subject to a knocking noise when you are in reverse with your Mercedes Classe C 2 and this noise tends to increase as you gain speed. It is plausible that you are going through a serious problem that needs to be resolved right away before wrecking your entire gearbox.
