Re: Steering wheel shimmy anybody?

As a follow up, I had my tires rebalanced by the shop, which by the way got a brand new balancing machine. With the recommendations from this thread the shimmy is completely gone! It rides like silk now, as a '16 with brand new tires should. Thanks for the info guys!

Glad you finally found a solution. I wish I would have known about this when I had my 2014, as I was still dealing with it when I traded for my 2017. Knoock on wood, my 2017 is fine but it's good to know it wasn't actually the tires, in most cases. BTW, where did you end up going to have this done?

I gave the dealer one last shot and they got it right on the third try, it was pretty frustrating though. Way too much money to be dealing with this kind of stuff. I really try to be loyal to american cars but this type of stuff sure makes it tough. If the engine wasn't so sweet I don't think I would put up with half the run around! Every time I hit the start button though I kind of forget all the headaches I've had in the 2 months of ownership.

Re: Steering wheel shimmy anybody?

FYI - Believe these two docs should be added to TSB's 22-001-14 & 22-003-14


Reason: RoadForce and SmartWeight combined do a great job of identifying an opportunity to index the tire & wheel for a "more round" assembly and use less wheel weights by focusing on the "Static" unbalance. The problem is all the focus is on "Static" which is up and down movement of the assembly from an assembly and balance prospective. The opportunity of a Shimmy condition in our vehicles is extremely high after RoadForce and Smartweight since the focus of correction is on Static and leave a perceived acceptable amount of "Couple" Unbalance in every assembly.


I am attaching two documents which discusses the importance of mounting the wheel correctly to the balancer (#1 Reason for vibration related comebacks) and Residual Unbalance phenomenon (#2 Reason for vibration related comebacks). The reason these two things are so important is they are most common reason for the issue but also the most common issues that are ignored and not addressed. People should a whole lot less time worrying about RoadForce when they should be worrying about the basics. Unfortunately for most shops their equipment is doing the assumptions for them and so the right decisions on correcting for conditions can't be made properly. Customers should be asking shops if they have a Direct Drive Coats Machine with ProBalance Technology, Low Taper Collets, and Adjustable pin Plates. If they do then you are Good to go! Hope this info helps.

I followed Hennessys advice and had my wheels balanced by a shop with a COATS balancer which they put in fine mode and took the weight correction down to .1 in addition they used the low tapper collets. Wheels are smooth at 75 now and this corrected what road force didnt. Thanks for thd advice Hennessy
