knocking from engine side?

[vyckius]

Hello,
We have 2015 leaf. We are moving car on parking position and get hearing knocking from engine upper side. Then hard driving or stopping also hearing this knock. Any ideas what it can be? https://www.youtube.com/shorts/MjJahqDn5OA

If u are rocking the car front to back when car is in park then I think it's normal. I've pushed on my car before and it made that noise. When does ur car make this noise ? Driving ?

 

[vyckius]

I hear the sound also hard acceleration and braking. Strange if it is normal?

Not normal. If u can check the gearbox mounts,and motor mounts maybe something is broke/loose ? How many miles on the leaf?

 

[vyckius]

Engine and gearbox mounts are good. ~45k miles odo. May seems from inverter this sound. But what can be wrong?

Next thing I would check are the CV axels , jack it up and give them a good spin and inspection. What make u think inverter?

 

[vyckius]

Checked CV joints. Everything in transmission looks good. It was also lifted and checked. No ideas from mechanics. Sound is coming from inside...

Next thing I would do is drain the gearbox and check for any debris , after draining when u have drain hole open check inside with a magnet that there is nothing g loose sitting in the bottom . There are some posts on the site with bad gearboxes.

There is a TSB to cover that. You are well beyond the warranty so it will cost you "something" and won't hazard an estimate as some have claimed to getting it done anywhere from free to 150ish sooo...

there is http://www.tsbsearch.com You will have to filter. This was an issue that covered several Nissan models so you will want to narrow it down a bit. When I get home, I may try to look it up


EDIT

Ok, found this. As mentioned it covers SEVERAL models so only copying the LEAFs involved.
