Classical reverse Jeep Grand Cherokee noises and some tips to look after your gearbox
Why does the reversing of my Jeep Grand Cherokee make a different noise from my other speeds?
De facto, adding all gears, bearings and pinions into a gearbox is a difficult process. The noise induced by the reversing of your Jeep Grand Cherokee 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 much less important 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 car in the revs, you risk to burn your clutch or gnawing at the gearbox pinions. - Never reverse while the car 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 put in on the gears will be enormous and you will produce 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 usual if you hear a reverse noise on your Jeep Grand Cherokee if you shift gear under these conditions.
