Classical reverse Volvo Xc40 noises and some tips to preserve your gearbox
Why does the reversing of my Volvo Xc40 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 created by the reversing of your Volvo Xc40 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 less important than with spur gears chosen 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 idea. In fact, the pressure you will exert on the gears will be significant 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 experience a reverse noise on your Volvo Xc40 if you shift gear under these conditions.
