Pulling my driver hard left

A straight pull or a pull hook

Too strong a grip will do it

Keep your right elbow tucked in on your downward swing. It will stop that with a quickness. But you have to finish your swing or else you’ll start pushing it to the right.

Pull left is my miss too.

My issue is being “out of sync.” I’m not flexible anymore. My hips and shoulders are not jiving. Shoulders turning faster than the hips bringing the clubhead more out to in and creating a pull.

With driver, I’d guess you are just like the rest of us, and tend to swing too fast which makes it more challenging to stay in rhythm.
My trick to stay in rhythm, is a tempo queue. Say ERNIE ELS.
ERNIE on the back swing. ELS down to contact. (3-1 tempo)

Just what works for me. Sometimes. :)

All good advice....Also may be hanging back too much w the Driver. Easy to do when overswinging or trying to help it launch. Get weight to your left side on downswing.

OP I sometimes start doing that and I found out the reason I did it(which is very common) is having your front shoulder way to far left due to the ball being in front. You have to remember to push that back shoulder back at adress to get everything back in line

I would never do it on irons since the ball is in the middle of stance. See below visual
