Classical reverse Lexus NX noises and some tips to look after your gearbox
Why does the reversing of my Lexus NX make a different noise from my other speeds?
De facto, integrating all gears, bearings and pinions into a gearbox is a difficult exercise. The noise caused by the reversing of your Lexus NX 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 important than with spur gears chosen for the reverse gear.
Tips to limit 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 choice. 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 Lexus NX if you shift gear under these conditions.
Diverse Lexus NX reversing noises and their origins
Finally in this section, we will move on to what you are probably most excited about in this document, to find out about the source of reversing noise on Lexus NX. Here are the 3 typical noises you may be victim of.
I hear a grinding noise when starting in reverse gear
If you perceive a grinding noise when you start in reverse with your Lexus NX, 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 plausible that due to their wear the silentblocks no longer absorb the engine vibrations well.

An increased reverse knocking noise on Lexus NXX
If you are subject to a knocking noise when you are in reverse with your Lexus NX and this noise tends to build up as you gain speed. It is plausible that you are going through a serious trouble that needs to be resolved right away before wrecking your entire gearbox. In fact, an intensifying rattling noise means that the gears are damaged. If they are, debris will disperse to the rest of the box and damage other gears before long. Take your vehicle to your technician quickly or read this content about gearbox noise on Lexus NX for more data.
I acknowledge a noise when I go in reverse
Experiencing 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 Lexus NX 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.
