1996 Honda Accord axles

There is a play in the inner cv joint when I m underneath the car an push the cv joint up and down also when I turn the wheels by hands forward and backward there is a play

What can causes a humming sound when only put car in gear.I jacked up the the front car and put car in gear when I push gas pedal the wheel turns and hear humming sound coming from the engine. The transmission fluid is red color and in level.I checked the power steering pump, the alternator and the distributor the sound is not coming from there and I checked the wheel bearing too I used the screwdriver to hear if there is any noise nothing. What could be the source of noise

This is a update
I drove the car in the freeway and there is that humming noise I put the car in neutral and still the humming noise was there
