Classical reverse Mercedes Classe E 5 noises and some tips to maintain your gearbox
Why does the reversing of my Mercedes Classe E 5 make a different noise from my other speeds?
De facto, integrating all gears, bearings and pinions into a gearbox is a difficult exercise. The noise generated by the reversing of your Mercedes Classe E 5 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 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 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 idea. 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 destroy the gears of your gearbox at speed by doing so. It will therefore be completely normal if you find out a reverse noise on your Mercedes Classe E 5 if you shift gear under these conditions.

If you perceive a grinding noise when you start in reverse with your Mercedes Classe E 5, 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 generated 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 situation, do not hesitate to browse this paper for more details about strut mount noises on Mercedes Classe E 5.
