Could be the leafs, tierods. Did you get an alignment after the work was done. if not your left and right side could be fighting each other. Maybe now that your front end is tight again, your just feeling the road.

The alignment was done but something is still wrong it could be a combo of things. The front end starts bouncing like its on a spring board. I can hit the throttle and make it stop but when I'm doing like 60 it starts really vibrating and the vibration will only go away with a change off speed.

Spring bushings come to mind, bad shocks.

Check the u-joints on the steering column, steering box, and shaft.

If you have shimmy in the steering wheel, the problem is with the front tires out of round/out of balance. If you feel it more in the seat, but the front also "shakes" without the steering wheel shimmy, the problem is with a drive tire out of round , or out of balance. Alignments, spring pins, king pins, springs will NEVER fix a shake or bounce or shimmy. This is caused from a rotating part that is constantly generating unbalanced forces to cause and sustain the shake or bounce. Rims can be slightly off center to the hub and cause big-time shakes. Tires can be mis-mounted off center in the rim and cause the same.
