93 Justy 2wd.

Going down the road under acceleration it feels like the wheels are out of balance (bouncing). Let off the gas it is smooth, ad gas and vibrates or bounces again. This just started about 2.000 miles ago and is getting worse. Both CV axles were replaced about 4,000 miles ago and there is no noise. I noticed the top engine mount is bad and the rubber is tore. Recon that could have anything to do with it? I think I will have balance checked. However I would think if out of balance they would vibrate at a certain speed where under acceleration or not. Anyone's thoughts?

more than likely when you replace that moter mount it will go away. if the rubber is missing or messed up when you give it power it twist the moter and with the rubber isn't there to take out vibration
