Whirring Noise In Rear End, 2011 Sienna AWD - Whirring noise in rear on 3rd generation Toyota Sienna. Several owners have reported same problem and can be found in this forum. To fix this issue is expensive and seems the Toyota Rav4 had same issues and there is a warrany enhancement. Sure would be nice to have Toyota honor this part outside of a normal warranty for Sienna owners.
I'm owner of Toyota Sienna 2011
5 years 2-nd owner 79k miles
and experience whirring noise in rear after visiting Toyota Dealers in Danvers without any success accept price tag for replacement 1.9k rear differential coupler. A few drivers have that same problems:

After that do some research and find the other owners experience that same issue find that TSB #TSB-0080-13 NHTSA ID #10052631 with model RAV4 use this same differential coupler have warranty enhancement.
for now i will fix that because of 3 kids on board and I don't want to risk to stall diff. when I drive...
In my opinion it is flow in dsg. to blow up bearings
