1. Have the truck blocked up and check the wheels for lateral runout and a bent condition. These will often not get caught by checking balance. If you find a wheel not running true, swap it with another to see if it’s the wheel or a truck component- axle, hub, etc.
2. Make sure the shop doing the balancing uses a pin plate to mount the wheel while balancing. That centers the wheel the way it will center on the lug studs, and not on the center borehole.
I had to have two of the wheels on my Laramie straightened by an aftermarket wheel shop, when the truck was new. My shake has returned and I have a third wheel that will get straightened when I mount new Michelin’s this month. And no, I don’t hit curbs, park stops, or chuckholes. All the wheels on my truck ran out of true when new, and I’ve only straightened enough of them as needed to reduce or eliminate my console shake at the time. It’s enough to make me look at aftermarket wheels...
best,
