Classical reverse Mercedes Benz M Class noises and some tips to preserve your gearbox
Why does the reversing of my Mercedes Benz M Class make a different noise from my other speeds?
De facto, adding all gears, bearings and pinions into a gearbox is a difficult action. The noise made by the reversing of your Mercedes Benz M Class is logical. It can be explained in a fairly simple way. In fact, 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 more quiet than with spur gears chosen for the reverse gear.
Tips to reduce wear on your clutch and gearbox
