Classical reverse Kia Sorento noises and some tips to look after your gearbox
Why does the reversing of my Kia Sorento make a different noise from my other speeds?
De facto, integrating all gears, bearings and pinions into a gearbox is a difficult action. The noise caused by the reversing of your Kia Sorento 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 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:
Certainly, 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 enormous and you will develop 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 perceive a reverse noise on your Kia Sorento if you shift gear under these conditions.
