had tires and rims checked at tire shop neither are the problem. ball joints replaced. it was aligned 2mths ago. and I'm still getting wobbly steering at any speed. I can give it gas and let off pedal and coast and I feel it too. any ideas?

 

Something is worn out. Use to be when they did a front end alignment they would replace all worn out parts. How many miles on your ride? Take a look at the front lower control arm bushings.

 

Also look at strut mounts

 

have you checked the wheel bearings? with it on the ground , grab a wheel and try rocking it back and forth ( to you and away from you) and listen for play.

After that, put someone in the car, engine off. get them to rock the steering wheel side to side while you watch all the steering components..

 

My death wobble was extremely violent at highway speeds. It ended up being worn out control arm bushings. I replaced them and it has been smooth sailing since.

 

Depending on if your steering components are original or the mileage on them, save your pennies and replace everything up front. Center link, idler arm, inner/outer tie rods, tie rod sleeve, control arm bushings, end links, sway bar bushings, strut mounts and struts (not necessarily needed but nice to have). That will make the car much nicer to drive and also much safer for you and those around you.
