Usually when I see this, it comes from a passive lower half, and active upper half.
When you say,"getting out on the front side too quickly", it's possible if the downswing is lead/dominated by the arms/shoulders.
It is unlikely if you begin the downswing with a weightshift to the left foot.
Think of throwing a ball, or bowling.
The left foot is planted, weight is transferred to it, and a chain reaction is started moving upward-finishing with the release.
This is an athletic move.

Typical poor golf swing- the downward motion is lead by the arms/shoulders which turns the hips, ending with the left foot lastly getting planted. Backwards and unathletic.

You want active lower half; reactive upperhalf.

To see this in action, stand behind golfers on the range.
Watch the hands/grip at the top of the backswing.
If the first move the hands/grip makes when changing directions is down (or "in the slot"), then weight is being transferred properly (from ground up, causing a slight lateral drive with the hips before rotating, which pulls the club down).
If the first move the hands make from the top is not down, but out (or "over the top") then the downswing has been initiated with the upper body.
This rerouts the path of the club to an outside-in path, and steeper than ideal.

I think of a qb, or pitcher, or centerfielder throwing home, or bowler.
Wind up (weight on right foot), stride, release.

If the order is right, usually the path is too.
