It is never pleasing to listen to a sound on your vehicle that you don’t know where it comes from. You may be thinking about what to do when you find a reversing gear noise that continues on your Mitsubishi Pajero? Any gearbox issue can be critical, but before making sure, it is better to do a few checks. Our team has made this document to help you resolve it. First, we will see what the sources and the different gearbox noises can be on Mitsubishi Pajero, and second, what are the solutions available to you.
Classical reverse Mitsubishi Pajero noises and some tips to preserve your gearbox
Why does the reversing of my Mitsubishi Pajero make a different noise from my other speeds?
De facto, adding all gears, bearings and pinions into a gearbox is a difficult action. The noise created by the reversing of your Mitsubishi Pajero 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 used for the reverse gear.
Tips to reduce wear on your clutch and gearbox
- Don’t give a big boost:
In fact, 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. Indeed, the pressure you will put in on the gears will be monumental and you will generate 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 common if you experience a reverse noise on your Mitsubishi Pajero if you shift gear under these conditions.
Diverse Mitsubishi Pajero reversing noises and their triggers
Finally in this section, we will move on to what you are probably most interested in this page, to find out about the source of reversing noise on Mitsubishi Pajero. Here are the 3 typical noises you may be victim of.
I acknowledge a grinding noise when starting in reverse gear
If you listen to a grinding noise when you start in reverse with your Mitsubishi Pajero, it may be the engine mounts that are tired. Certainly, when the engine is in reverse gear, due to the pinions we saw above the vibrations generated 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 read this paper for more details about strut mount noises on Mitsubishi Pajero.
An increased reverse knocking noise on Mitsubishi PajeroX
If you are subject to a knocking noise when you are in reverse with your Mitsubishi Pajero and this noise tends to amplify as you gain speed. It is plausible that you are confronting a serious issue that needs to be fixed fairly quickly before destroying your entire gearbox. Indeed, an intensifying rattling noise means that the gears are damaged. If they are, debris will spread to the rest of the box and damage other gears quickly. Take your vehicle to your repair shop quickly or read this content page about gearbox noise on Mitsubishi Pajero for more information.
I notice a noise when I go in reverse
Hearing a noise when you shift into reverse is normal and connected to the gears and sprockets used in the gearbox. If, on the other hand, you have the feeling that your Mitsubishi Pajero 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.
