Classical reverse Mercedes Benz GLK noises and some tips to preserve your gearbox
Why does the reversing of my Mercedes Benz GLK make a different noise from my other speeds?
De facto, integrating all gears, bearings and pinions into a gearbox is a difficult exercise. The sound made by the reversing of your Mercedes Benz GLK 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:
Indeed, 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 plan. Indeed, the pressure you will apply on the gears will be monumental and you will generate 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 usual if you hear a reverse noise on your Mercedes Benz GLK if you shift gear under these conditions.

I notice a grinding noise when starting in reverse gear
If you notice a grinding noise when you start in reverse with your Mercedes Benz GLK, 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 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 circumstance, do not hesitate to browse this content page for more info about strut mount noises on Mercedes Benz GLK.
An increased reverse knocking noise on Mercedes Benz GLKX
If you are subject to a knocking noise when you are in reverse with your Mercedes Benz GLK and this noise tends to increase as you gain speed. It is plausible that you are going through a serious issue that needs to be fixed right away before ruining your entire gearbox.

Take your vehicle to your repair shop quickly or read this document about gearbox noise on Mercedes Benz GLK for more details.
I perceive a noise when I go in reverse
Listening a noise when you shift into reverse is normal and relating to the gears and sprockets used in the gearbox.

It is therefore time to empty the box.
