Wow, great news egl898. Glad you solved this annoying pulsating vibration. And the root cause seems to be a wrong torque of the axle locknut as Marko (estomax) said, which damages the wheel bearing and even the threads on the front axle... Have you an idea on how much would have costed...

@nlspace : I really like how you think. They said to lubricate "the entire (front or rear) wheel hub bearing surface". I think you have a point about the wheel bearings preload. The scary part here is that this preload, in my ignorant opinion, could also affect the transaxle/reduction gearbox...

@estomax Thx. This is an interesting lead. The axle nut I suppose is the same "lock nut" from this Nissan TSB tsb-ntb12-055f: https://www.carcomplaints.com/Nissan/Leaf/2015/tsbs/tsb-ntb12-055f.shtml I can see on 3rd page that 121 Nm torque is mandatory to prevent a "clicking" noise when...

Hi, Just a quick update on this. I jacked up my car to control the front wheel bearings but didn't found anything particular apart from a noise coming from the reduction gearbox . Cannot say if it is normal or not just by manually rotating the wheel at very low speed... @egl898 any update on...

Thank you egl898 for finding the right words for this issue: "pulsating vibration/humming from the front of the car". In my case the vibration is also reduced or disappear when turning right at any speed. As LeftieBiker and Steelcity said it could be a CV joint or a wheel bearing. I'll try to...

:) Thx Thorri! I'm wondering if we are the only users affected by this noise/vibration or it's something general for this model (maybe a resonance frequency for the Leaf) but nobody paid attention ... Anyone?

Hi Thorri, I bought 3 weeks ago an used 2014 Nissan Leaf, and I was searching the internet for the same problem: high frequency vibrations at certain speeds when I found your post. In my case the same vibrations are at 62-63 Km/h, lower intensity, and 91-92 Km/h with higher intensity. It...
