Hello, new to the boards, but not new to being a Lexus owner. Second time owner of a Lexus. I am a certified Lexus / Toyota technician. I am also a Maryland State Inspector. If you need someone to look your vehicle over still. I can do this for you if you are still interested in having someone look at the car.

I am new to the boards, just joined today. I am also a second time Lexus owner who happens to be Lexus / Toyota certified technician. What you are talking about doing is called bumping in the mechanics world. We do this because the crank bolt can be impossible to get off with impact guns. Some just don't have enough torque to break the bolt loose. Your standard crank bolt requires a 22mm socket. You will also need a half inch breaker bar, at least 18" inches in length. The engine turns in a clockwise manner. Place the socket on the breaker bar and place the socket w/ the breaker bar onto the crank bolt. Make sure the lower end of the bar is touching the ground on the right side of the crank pulley. Remember the engine will spin clockwise so the bar must be in a resting position that will not allow it to move when you do a quick crank of the engine. DO NOT START THE VEHICLE. JUST TURN THE KEY VERY QUICKLY SO THE VEHICLE'S ENGINE BEGINS TO TURN. THEN QUICKLY TURN THE KEY BACK OFF. IT SHOULD BE ONE MOTION (ON/OFF). Do this repeatedly until the crank bolt is loose. I hope that this helps you with your situation. Good Luck!
