how pressing to get fixed -bushing bad on lower arms
First get a second option, though you chose not to state how many miles you have on your car, seems early to have bad bushings. But if they are bad, it can definitely affect the cars steering and handling.
If they are letting the control arms move around they need replacing. If there are merely cracks in the outside of the rubber, that doesn’t require replacing.
If the car has 100 - 150K and the bushings are so bad, to the point that you can really hear a clunk and it’s affecting the steering . . . you need them replaced yesterday
