Just look at the PDF, it lists lots of Nissans ...

Re: Clicking noise during acceleration and decceleration

Reading through the TSB it doesn't seem like this is more than an annoyance. I occasionally hear a faint tick sound in my Leaf on acceleration or deceleration but it almost sounds like normal gear lash. I was planning to just ignore this. Any experiences out there to contradict that sentiment?

Re: Clicking noise during acceleration and decceleration

I purchased my 2016 SV about 4 weeks ago. The clicking noise started about a week ago. After reading the service bulletin that addresses this issue, I called my local Nissan dealer and spoke with the service manager. He knew exactly what I was talking about, and that the remedy is what was detailed in the service bulletin.

I had the repair done yesterday, it took about 90 minutes, and set me back $150. The service manager told me that, while it’s annoying (which it WAS), it’s unlikely that that there would be any damage caused by not fixing it.

I am now enjoying only the gentle whirr of the motor, the way the EV gods intended.

I am having the one click issue on releasing and pressing the accelerator pedal with my 2018 SV. Can you tell me which service bulletin is was?

I don't have the number, but I believe it's the one for re-torquing the axle bolts.

Re: Clicking noise during acceleration and decceleration

AFAIK, the TSB is for 2011 - 2017 LEAFs only

It's possible that your wheel lug nuts aren't tight enough, an easy thing to check...

Re: Clicking noise during acceleration and decceleration

My car had both the axle clicking noise and a different click coming from the brake pads shifting in the calipers. The dealer performed the axle nut TSB and we haven't heard that click since. They also "lubricated" the brakes, and it went away for a while, but has returned. Point being, while the axle clicking appears to be very common, there are other potential sources that sound similar.

Re: Clicking noise during acceleration and decceleration

Updated TSB that includes 2018 and newer LEAF vehicles. And it seems to include quite a few other Nissan vehicles. Wondering at what point does this issue require a more permanent fix given that issue has returned on both my LEAFs?

Re: Clicking noise during acceleration and decceleration

I just completed the repair for the Clicking Noise during acceleration and deceleration. Mine was clicking only on the left side. This was quite easy. I started with the front left. Jacked it up, remove the cotter pin, lock shield, washer, and nut. I noted the torque needed to remove the nut, and it was not much at all. Once removed, it is easy to push the spline back about 20mm which compresses the drive shaft spline. It does not stay so I had someone hold it in while I applied the grease. Mine did not have much corrosion, but if there is, screw the nut back on and use a rubber mallet and see if it will move. I used some moly grease but I imagine anything similar would work fine. Using a split tongue depressor, i carefully applied the grease on the splines on both the inside and outside. Be careful not to drag any dirt into the grease. If you touch the dirty area with the grease, wipe the stick and start over. Remove the pressure and the spline shaft will move back a bit. Next the Belleville washer is placed on with the concave side towards the inside. This also helps push some grease into the splines. Next screw on the nut. I used the same nut and washer and here is why. In my decades as an aircraft mechanic, there were only some instances where a nut was required to be changed, usually on a critical engine part. The nut on the Leaf is quite large and looked perfect. Same with the washer. One could surmise that the spring washer was flattened and should not be used again, but when the nut is tightened up, the washer is flattened and would not know it was ever dished. It looks like Nissan changed the torque specification on this nut to correct the clicking noise from (125 Nm, 92 ft-lbs) to (200 Nm, 147 ft-lbs). This requires a big torque wrench and I think it was a 32mm socket. Then clock the lock shield and re-insert the cotter key. The nut on the right side front was definitely tighter than the left. Did the factory have an out of calibration or mis-set torque setting on the left side? Anyway, there is no more clicking noise coming from the front left wheel. Letting this go does not seem like it would ever cause a problem, it is just annoying. This repair takes only a few hours for both sides. Easy
