It is never pleasant to acknowledge a sound on your vehicle that you don’t know where it comes from. You may be questioning what to do when you notice a reversing gear noise that persists on your Porsche Cayenne? Any gearbox trouble can be critical, but before making sure, it is better to do a few checks. Our team has made this article to help you fix it. First, we will see what the sources and the different gearbox noises can be on Porsche Cayenne, and second, what are the solutions available to you.
Classical reverse Porsche Cayenne noises and some tips to look after your gearbox
Why does the reversing of my Porsche Cayenne 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 generated by the reversing of your Porsche Cayenne 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 limit 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 practice. In fact, the pressure you will apply on the gears will be significant and you will create 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 normal if you perceive a reverse noise on your Porsche Cayenne if you shift gear under these conditions.
Diverse Porsche Cayenne reversing noises and their origins
Finally in this section, we will move on to what you are probably most excited about in this document, to learn about the origin of reversing noise on Porsche Cayenne. Here are the 3 typical noises you may be victim of.
I experience a grinding noise when starting in reverse gear
If you acknowledge a grinding noise when you start in reverse with your Porsche Cayenne, it may be the engine mounts that are tired. In fact, when the engine is in reverse gear, due to the pinions we saw above the vibrations made by the gearbox are higher and it is therefore plausible that due to their wear the silentblocks no longer absorb the engine vibrations well. In this situation, do not hesitate to check this content page for more details about strut mount noises on Porsche Cayenne.
An increased reverse knocking noise on Porsche CayenneX
If you are subject to a knocking noise when you are in reverse with your Porsche Cayenne and this noise tends to increase as you gain speed. It is plausible that you are confronting a serious trouble that needs to be solved as soon as possible before wrecking your entire gearbox. In fact, an intensifying rattling noise means that the gears are damaged. If they are, debris will disperse to the rest of the box and damage other gears quickly. Take your vehicle to your mechanic quickly or read this content page about gearbox noise on Porsche Cayenne for more details.
I listen to a noise when I go in reverse
Experiencing a noise when you shift into reverse is normal and related to the gears and sprockets used in the gearbox. If, on the other hand, you have the feeling that your Porsche Cayenne reverse gear makes more noise than before, it is plausible that filings have been made and are moving around in it. It is therefore time to empty the box.
