Steering wheel shimmy anybody?

I bought my 14 srt with 22K on it. The dealer installed new P Zero's to pass inspection so it came with brand new road force balanced oem tires. Since day one At any speed 60+ the steering wheel will shake and you can feel it through out the entire truck.


I could not stand the curb rash on the oem wheels from the previous owner and hated the way the run flats rode. I installed new reproduction spiders with new Toyo proxes STII tires and they were road force balanced. Also had them take out all of the camber. Trucks rides and drives awesome now EXCEPT when you hit 60+ the steering wheel still shimmy's. That did not change at all which tells me the problem is not in the wheels or tires. Feels identical.


Anybody else have this problem with a WK2 SRT? All the info I find on this problem is with the WK1 SRT8's and those are fixed with new lower control arms.

Re: Steering wheel shimmy anybody?

shimmy is from couple unbalance too high which happens when a Hunter balancer is left in Smartweight mode. Tell them to use collets and pin plates when mounting wheel on balancer and then take the balancer out of Smartweight mode. This happens all too often on Roadforce balancers and the techs kick them out the door all too often.

Re: Steering wheel shimmy anybody?

I have the same issue at about the same mileage. 2014 SRT. Had a brand new set of Pirellis replaced with same, no change. Had wheels road force balanced again, different shop, no change. Had front wheel bearings replaced, no change. Had Chrysler zone rep look at it, they road forced again and after 100 miles of test driving, said it was "within spec." Seeing the steering wheel visibly shimmy at speed is not "within spec" in my world. Bought another set of Spider Monkeys (take offs from a 2015 SRT) and swapping them on Tuesday. If vibration is still there, it's being dropped off at the dealer.

My wife's 2014 Overland is glass smooth at similar speeds and mileage so I know the GC can be vibration free.

Re: Steering wheel shimmy anybody?

Roadforcing your tires is not a balancing process, it is checking for a run out condition in the assembly to see if it can be "More Round". Unfortunately there are so many shops from dealerships to retail tire shops who don't understand how to balance properly. Again I would demand that they turn "Smart Weight" OFF. Balance in conventional mode and put the balancer in "Fine" Mode which shows the unbalance under .25oz. If they don't know how to do this then either educate or move to another shop. The video in link shows what "Smart Weight" Balance does which is leave up to 1.5oz of "Couple Unbalance" in the assembly which will lead to a "Shimmy". Mounting errors account for over 60% of vibration comebacks and "Residual Unbalance", which Smart Weight leaves a bunch in the assembly, account for over 25% of vibration comebacks. RoadForce only accounts for less than 5% of comebacks. What you are describing is a "Residual Unabalance" issue not a RoadForce Issue.

Re: Steering wheel shimmy anybody?

I too have a slight shimmy at highway speeds. This was present with OEM Goliath wheels & Pirelli tires, and OEM Spyder Monkeys with Toyo Proxes tires, with alignments done. I just gave up and deal with it.

Re: Steering wheel shimmy anybody?

Re: Steering wheel shimmy anybody?


Thanks for the links!


I have to take mine back in again due to the steering directed headlights not working so I am going to print this out and hand it to them and have them replace the wheel bearings while they have the truck. If that doesn't fix the issue I will take the truck back to the tire shop. The tire shop I use specializes in high performance wheels and tires and normally does a great job. All the performance shops around here use them.


Here is a video of the shimmy. Doesn't look to bad in the video but trust me you can feel it through out the entire truck.

Thanks again for the suggestions guys!

Re: Steering wheel shimmy anybody?

I know this is a TSB about replacing wheel bearings. Sounds like it corrects the condition for a while. The new bearings are tighter and actually changes the suspensions sensitivity level for a while. I am 100% confident my suggestion will fix your issue. I see this issue everyday and know how to correct for it and train shops all around the country on how to correct for it too. I only wish I could discuss and show a Chrysler Engineer on how to correct for it.

Re: Steering wheel shimmy anybody?

Tire with Zero Roadforce definition: Tire/Wheel has No Radial Runout and is ready to be Balanced. This is where the problem starts. Again on a Hunter Machine the balancing software or SmartWeight hides the "Residual" Couple Unbalance. Couple Unbalance is a vibration on inside plane and a vibration on outside plane exactly 180 degrees apart and at exactly the same amount. The claim is that this "Residual" leftover amount will not be felt by the driver. With all the vibration issues that Jeep owners experience do you believe this is an accurate statement? It is not and hence why we have an Industry problem that even most OEM Manufacturers choose to ignore.

Re: Steering wheel shimmy anybody?

Hennessy my new friend, you solved my problem!

To be fair, Aaron at Northwest Frame and Alignment in Zionsville, Indiana never uses the SmartWeight feature for exactly the reasons you stated, so when I showed him your post he said, "That's exactly why I don't use SmartWeight."

$58.00 later, I have something 3 trips to Chrysler and 2 trips to a GM dealer (where I bought the SRT), which included swapping out a brand new set of Pirellis, two new front wheel bearings and 5 re-balancings, couldn't give me - a smooth ride.

My question now is, why does Hunter even offer this BS feature? To save lead, time, to be eco friendly? I don't get it.

Thank you again for solving this seemingly unsolvable problem. Now I can use my extra set of Spider Monkey's for winter tires.

Re: Steering wheel shimmy anybody?

That's Awesome Ron-Indy! I am so glad you go your problem solved! It is total BS that anyone has to deal with what you had to deal with.

To answer your question why does Hunter even offer this BS feature... Hunter pitches this to the shop as a way to save money on wheel weights. This potentially could be a thousand dollars or more over a years time. The problem is just what you experienced, a crappy ride. You as the consumer pay for a Balance and Hunter simply does not deliver with SmartWeight.

So glad your ride quality is fixed.
