I too, unfortunately, get the shanks on occasion. Mine come from not clearing my hips which causes the clubhead to move away from me just enough to catch the ball on the hosel. When that happens, it tells me my lower body is moving too fast, so I try to start my downswing with my arms leading the way. I doubt my arms are actually leading the downswing, but that's what I feel like I'm doing. That typically gets me hitting the ball solid again. I also try to slow my tempo down.
So when you say you're not "clearing the hips" do you mean that your hips are moving laterally? I struggle with this issue and I also have to try to "feel" like I'm starting my downswing with my arms on iron shots. I "feel" like I'm keeping my lower body still while dropping the arms straight down (or at a slight angle toward the ball if I'm trying to draw it or if I have a lie with the ball above my feet) If I don't try to restrict my lower body from sliding laterally I can hit some pretty nasty shanks with the irons. Also, narrowing my stance a bit has helped. The wider your stance, the more your legs and hips will move laterally. I have tried to initiate the downswing (with the irons) by just clearing the left hip and letting the arms be passive but I tend to clear the left hip too fast and with too much lateral movement. With the 3 wood and especially driver, I keep the arms passive and just clear my left hip on the downswing. These clubs are too long and heavy for me to "feel" like I'm reliably swinging them with just the arms on the downswing. You can't shank a wood, thank god. But you can hit a lot of big push fades or push hooks, depending on open or closed face at impact.
