Just had a new control arm out on my right rear and also new all season tires on the back. My handeling was bad so I decided to get it aligned at Mr tire but it still is handling bad, at high speeds it pulls in both directions and fish tails if I rock the steering wheel. Is this because Mr tire did a bad job aligning it? It's not because I have new all seasons in the rear and mid-lifed summer in the front is it? Thanks!

 

Bring it back and tell them the situation. They should know what to do then, good luck.
