Classical reverse volvo xc70 noises and some tips to look after your gearbox

De facto, integrating all gears, bearings and pinions into a gearbox is a difficult action. The noise generated by the reversing of your volvo xc70 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.
