engine was replaced in my 2008 BMW 750 li. As soon as I picked it up I could feel the car pulling to the left and the car shakes a lot. Did they disassemble the suspension in order to replace the engine?

What is your question?

The dealership rebuilt the engine. They pulled the engine and transmission out in order to rebuild it. once it was complete I picked it up and as soon as I drove away I could feel the car shaking a lot. The steering wheel shakes, the car shakes bad and it pulls to the left.
