Front end Groan

I recently replace the wheel bearings on my 2017 5th Gen, 90K miles
as suggested by toyota service center,
However sound and feel is still there.
(1st noticed the grinding/warbling sound after going back into 2wd after using 4wd.) never had problem prior. Sound continued so I took to dealer to track noise.
They said it was wheel bearings, but when they were removed they still turned very smoothly, and we questioned if they were actually bad, went ahead with install BUT the noise and feel is still there but only between 37mph and 55mph.
Any one else have this problem??

Probably more but I'll stop at 2.

If out of warranty I'd suggest the ECGS and call it a day.
