It is never enjoyable to acknowledge a sound on your car that you don’t know where it comes from. You may be wanting to know what to do when you find a reversing gear noise that persists on your Fiat Doblo? Any gearbox trouble can be severe, but before making sure, it is better to do a few checks. Our team has written this document to support you eliminate it. First, we will see what the origins and the different gearbox noises can be on Fiat Doblo, and second, what are the solutions available to you.
Classical reverse Fiat Doblo noises and some tips to maintain your gearbox
Why does the reversing of my Fiat Doblo make a different noise from my other speeds?
De facto, integrating all gears, bearings and pinions into a gearbox is a difficult process. The noise generated by the reversing of your Fiat Doblo 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 much less important than with spur gears used 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 practice. In fact, the pressure you will apply on the gears will be significant and you will develop 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 Fiat Doblo if you shift gear under these conditions.
Diverse Fiat Doblo reversing noises and their causes
Finally in this section, we will move on to what you are probably most enthusiastic about in this document, to learn about the source of reversing noise on Fiat Doblo. Here are the 3 typical sounds you may be victim of.
I listen to a grinding noise when starting in reverse gear
If you acknowledge a grinding noise when you start in reverse with your Fiat Doblo, 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 produced 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 circumstance, do not hesitate to read this document for more information about strut mount noises on Fiat Doblo.
An increased reverse knocking noise on Fiat DobloX
If you are subject to a knocking noise when you are in reverse with your Fiat Doblo and this noise tends to build up as you gain speed. It is plausible that you are dealing with a serious trouble that needs to be solved quickly before destroying 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 in short order. Take your car to your auto mechanic quickly or browse this content page about gearbox noise on Fiat Doblo for more data.
I acknowledge a noise when I go in reverse
Listening 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 Fiat Doblo reverse gear makes more noise than before, it is plausible that filings have been produced and are moving around in it. It is therefore time to empty the box.
