Classical reverse Toyota Hilux 3 noises and some tips to preserve your gearbox
Why does the reversing of my Toyota Hilux 3 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 Toyota Hilux 3 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 employed for the reverse gear.
Tips to limit wear on your clutch and gearbox
- Don’t give a big boost:
Indeed, 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 practice. Indeed, the pressure you will exert on the gears will be significant and you will generate 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 typical if you perceive a reverse noise on your Toyota Hilux 3 if you shift gear under these conditions.
Several Toyota Hilux 3 reversing noises and their origins
Finally in this section, we will move on to what you are probably most curious about in this document, to find out about the cause of reversing noise on Toyota Hilux 3. Here are the 3 typical noises you may be victim of.
I perceive a grinding noise when starting in reverse gear
If you experience a grinding noise when you start in reverse with your Toyota Hilux 3, 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 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 case, do not hesitate to consult this paper for more details about strut mount noises on Toyota Hilux 3.
An increased reverse knocking noise on Toyota Hilux 3X
If you are subject to a knocking noise when you are in reverse with your Toyota Hilux 3 and this noise tends to increase as you gain speed. It is conceivable that you are dealing with a serious issue that needs to be resolved rather quickly before ruining your entire gearbox. Indeed, 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 car to your technician quickly or browse this content about gearbox noise on Toyota Hilux 3 for more information.
I find out a noise when I go in reverse
Finding out a noise when you shift into reverse is normal and linked to the gears and sprockets used in the gearbox. If, on the other hand, you have the feeling that your Toyota Hilux 3 reverse gear makes more noise than before, it is conceivable that filings have been created and are moving around in it. It is therefore time to empty the box.
