Classical reverse BMW X6 noises and some tips to look after your gearbox
Why does the reversing of my BMW X6 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 made by the reversing of your BMW X6 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 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 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 idea. In fact, the pressure you will apply on the gears will be significant and you will create 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 usual if you listen to a reverse noise on your BMW X6 if you shift gear under these conditions.
Diverse BMW X6 reversing noises and their origins
Finally in this section, we will move on to what you are probably most excited about in this content, to find out about the cause of reversing noise on BMW X6. Here are the 3 typical sounds you may be victim of.
I notice a grinding noise when starting in reverse gear
If you acknowledge a grinding noise when you start in reverse with your BMW X6, 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 made by the gearbox are higher and it is therefore possible that due to their wear the silentblocks no longer absorb the engine vibrations well. In this situation, do not hesitate to browse this content for more information about strut mount noises on BMW X6.
An increased reverse knocking noise on BMW X6X
If you are subject to a knocking noise when you are in reverse with your BMW X6 and this noise tends to amplify as you gain speed. It is possible that you are dealing with a serious problem that needs to be fixed very fast before wrecking 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 very fast. Take your vehicle to your technician quickly or browse this article about gearbox noise on BMW X6 for more data.
I hear a noise when I go in reverse
Listening 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 BMW X6 reverse gear makes more noise than before, it is possible that filings have been produced and are moving around in it. It is therefore time to empty the box.
