How much should engine rotate?

[Sock Monkey]

I had a clunking noise in my 2006 Mazda 3 front end. It turned out to the the struts bidding me farewell. In order to isolate the sound I put the front end up on axle stands, wheels off the ground and had a friend run it through the gears, fwd, rev. and stepping on the brake. I noticed the engine rotated quite a bit. There is a flange bolted to the bottom of the transmission right where the axle shafts come out of it and that then bolts to a shock isolated plate on the frame. I would say that flange travels perhaps 3/4" front to back or more when the wheels are turning and the brake is stepped on. There is likely a rubber or poly bushing where the transverse bolt holds the flange to the plate and then likely a rubber mounted seat which holds the plate to the frame. Should this stuff be shifting back and forth?

Thanks

Yes, This is rubber mount, It does shift about that much. Poke it with a screw driver to see if it rotten. I replaced mine with Poly long time ago, was a good upgrade.
