Classical reverse Isuzu D-Max noises and some tips to look after your gearbox
Why does the reversing of my Isuzu D-Max make a different noise from my other speeds?
De facto, integrating all gears, bearings and pinions into a gearbox is a difficult task. The sound generated by the reversing of your Isuzu D-Max 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 used for the reverse gear.
Tips to limit 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 plan. In fact, the pressure you will put in on the gears will be enormous and you will make 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 typical if you hear a reverse noise on your Isuzu D-Max if you shift gear under these conditions.
Different Isuzu D-Max reversing noises and their causes
Finally in this section, we will move on to what you are probably most excited about in this content, to learn about the source of reversing noise on Isuzu D-Max. Here are the 3 typical sounds you may be victim of.
I notice a grinding noise when starting in reverse gear
If you listen to a grinding noise when you start in reverse with your Isuzu D-Max, it may be the engine mounts that are tired. Indeed, when the engine is in reverse gear, due to the pinions we saw above the vibrations produced by the gearbox are higher and it is therefore conceivable that due to their wear the silentblocks no longer absorb the engine vibrations well. In this circumstance, do not hesitate to read this document for more details about strut mount noises on Isuzu D-Max.
An increased reverse knocking noise on Isuzu D-MaxX
If you are subject to a knocking noise when you are in reverse with your Isuzu D-Max and this noise tends to amplify as you gain speed. It is conceivable that you are dealing with a serious problem that needs to be fixed as soon as possible before ruining your entire gearbox. In fact, an intensifying rattling noise means that the gears are damaged. If they are, debris will propagate to the rest of the box and damage other gears quickly. Take your vehicle to your auto mechanic quickly or read this document about gearbox noise on Isuzu D-Max for more details.
I listen to a noise when I go in reverse
Listening a noise when you shift into reverse is normal and relating to the gears and sprockets used in the gearbox. If, on the other hand, you have the feeling that your Isuzu D-Max reverse gear makes more noise than before, it is conceivable that filings have been produced and are moving around in it. It is therefore time to empty the box.
