Hi all,
have a 2013 Pilot with 70k miles.
I am trying to pinpoint noise in rear differential.
it occurs 40-70 mph and is louder when vehicle shifts weight to left side. I have put new Honda AtM fluid in but the noise continues.
need help?
thanks!

 

Does it occur under load only or while coasting also.
Record it for us.

 

Both under a load and coasting
louder when shift weight of truck to right

 

I'd look at the wheel bearings.

 

we have checked wheel bearings last 2 brake jobs and they look fine.
sounds more like axle bearing or diff gears or pinion?
i did try to upload video but even when I shortened it - it exceeded 20 mb cutoff.
thanks

 

I would suspect the pinion. Side bearings will be on load only.
