Okay i replace the passenger side CV axle. I got to say it was a pain in the butt to get the cv bearing wheel on the passenger side off the bearing support bracket. If anyone does this the best way is to remove the support bracket and then gently hammer and slide it out, with the whole axial. Even with a hammer slide there is no way you could get my cv out if it is stuck on the bearing bracket. There's definitely a big difference in sound. It is not as loud but now I can hear it from the other side. Which I didn't replace both of them. But the best thing I found is my miles per kwh has gone up a lot. Like from round 3.8 to around close to 5. Most of my driving is around 30 to 40 miles an hour. This could be really interesting if people are getting lower miles per kw in older leafs and can't figure out why. I know it takes a little bit of time to redo the average but I've redone the average after I switched out a bunch of parts just last week and then this weekend.

I'm going to do the other side this weekend takes about a week to get the part in from RockAuto and then see if it totally gets rid of it. Even if it doesn't it gotten so much quieter now (not that it was loud) it really is not going to matter. I almost don't even want to do the other side but why not.

Was at a dealer for other reasons and had them check the noise today. It took some time for them to even notice it. They think it is the traction motor, but they said it is hard to pinpoint the source exactly so could be the reduction gear too, basically the noise was coming from the motor area when they lifted the car, so not a CV joint which is consistent with the symptoms as turning the wheels doesn't make the noise louder. Given a new traction motor is a $9.5k job the recommendation was to just drive the car until things get worse, which I'm going to follow to the letter.

I replaced my other cv axial. Still have the continuous clicking at low speeds. Everything has been replaced from the wheels to the reduction gear. So I agree either the motor or gear is making the noise. This is as far as I am going on this issue too.

The dealer mechanic I spoke with said they've done several failed traction motors replacements under warranty, makes me wonder how much time do I have left on mine.

I have 90K on mine right now with 12 bars. Going to be a big let down if the motor fails before anything else. Was hoping to have this car for a while. Now I am going to have to wait and see. Keep me updated if anything changes with the traction motor.
