I got four brand new tires front end alignment tie rods. I had a bad bearing in the back changed the bearing and hub out but every time I drive and hit 40 miles an hour, I get a shake in the motor. When I let off the gas it'll stop if I hit the gas a little bit and take off it also stops the bearings in the front end are also good so not sure what else could be the problem do you think it could be the motor mounts.

Is it a shaking of the engine or a shaking of the car when going over 40mph?

Hello,

I have seen the CV axles cause these issues. When the CV joint wears out it will not transfer the torque of the engine smoothly. Here is a guide so you can see how the parts work and I have included the replacement instructions in the images below in case you need them.

This video will show you the steps as well, it is a similar car, but the process is the same.
