Hey all, I have a 2000 impala, 3.4 engine. 280k, i know its horrible, don't know how it's still running. Anyways I was looking at the suspension and noticed the outer tie rods were bad so i replaced them. Now my car shakes at about 45 mph when i let go of the gas. Tires are pretty old but it did not shake before. I think it may be the tires, but I was wondering if anyone had any insight into why this might happen. I know I have to get it aligned after a tie rod replacement, but there are a couple other things I have to fix before the shop can align the vehicle.
