03 CR-V shake at 20 to 25 mph.

Hello, I have a 03 CR-V all wheel drive, when accelerating the car shimmies at 20-25 mph it’s not not felt on the steering wheel only the body. All other speeds regardless of load The vehicle drives smooth. I’ve replaced all motor mount and diff mount (lower). In the process of checking the u joints and replace the top diff mounts. Hoping I’m on the correct path and want your insight. Also are the top diff mounts need to be press in?
