Classical reverse Scion xB noises and some tips to protect your gearbox
Why does the reversing of my Scion xB make a different noise from my other speeds?
De facto, adding all gears, bearings and pinions into a gearbox is a difficult exercise. The sound caused by the reversing of your Scion xB 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 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 make 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 Scion xB if you shift gear under these conditions.
Different Scion xB reversing noises and their origins
Finally in this section, we will move on to what you are probably most interested in this document, to find out about the cause of reversing noise on Scion xB. Here are the 3 typical sounds you may be victim of.
I find out a grinding noise when starting in reverse gear
If you acknowledge a grinding noise when you start in reverse with your Scion xB, 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 conceivable that due to their wear the silentblocks no longer absorb the engine vibrations well. In this case, do not hesitate to browse this document for more details about strut mount noises on Scion xB.
An increased reverse knocking noise on Scion xBX
If you are subject to a knocking noise when you are in reverse with your Scion xB and this noise tends to increase as you gain speed. It is conceivable that you are confronting a serious problem that needs to be fixed fairly quickly before wrecking your entire gearbox. In fact, 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 before long. Take your car to your technician quickly or check out this content about gearbox noise on Scion xB for more data.
I listen to 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 Scion xB reverse gear makes more noise than before, it is conceivable that filings have been made and are moving around in it. It is therefore time to empty the box.
