Sway Question

Coming home driving south on I-405 in Washington, our trailer suddenly swayed. Our truck (Ford F150) briefly displayed a message about "trailer sway", which the Ford F150 displays when the trailer sway control has detected trailer sway.

The sway stopped almost immediately, and didn't happen again.

It was hot in Seattle area yesterday, barely any wind, we were driving about 60mph. My husband and I both freaked out, and he swore he was never going over 55mph again.

But still....what might have caused the sway?

Thanks for your help.

What brand and model weight distribution hitch do you use? What is weighting rating of the bars?

X2?

Have you been to the CAT scales? The Classics are the heavyweights of the AS line. You'll need the weights to properly set up the rig.
A quality WD hitch with integral sway control is a MUST with your 30'r.
What is the load rating of your tires? C,D,E.
LT (light truck), or P (passenger).

The Ford "sway control" does nothing to prevent sway, it only activates after sway is detected. Much better to prevent it.

Our '10 F150 has the tow package w/ the sway control option. With our single axle safari have had this happen a couple times caused by the "bow wave" from a bus passing us on interstate highways. According Ford its normal. The anti sway system on the truck applies brake to individual wheels on the truck to self correct and flashes the message on the dash. If the is no obvious reason for the message you may want to stop by a dealership and ask them to check the computer log on the truck for a malfunction. They also told me and while an underinflated tire will show the icon an overinflated will not, and just one overinflated can cause the sway message.

Thanks all for your replies.

We originally purchased a 2013 28' Flying Cloud with an Equal-i-zer sway control hitch. Four months later, we traded up to a 2013 30' Classic. The hitch was transferred from our Flying Cloud to the Classic, as per the dealer's recommendation.

I have the Equal-i-zer manual, but we're not sure of the specific model. Tomorrow, we're going to check out the hitch and make sure we know the exact model so we can answer your questions. And lesson learned for us, this is something we should already have answers.

Bob, not sure about the tires. Are you asking about the truck tires?

Anyway, the trailer did sway. Not much, but it was noticeable. And the sway ended almost immediately. I "felt" the brakes - but my husband didn't apply the brakes. So the truck must done it's job and corrected the sway. But that's speculation on my part

Is there anything else we should do or know?

Thank you all again.

If the truck detects sway, it will apply the trailer brakes to stop the sway, and the "sway" message will be displayed.

Thumbs up

It's a truck but may not have truck tires.
Look at the sidewall for the size and load rating. P for passenger, LT for light truck.

You will still need to get the WD set-up and sway control adjusted properly. A trip to the scales will help a great deal. Your trailer could very well approach 9klbs loaded for camping. Overloading the tires, tongue weight, payload and or axle rating is a possibility.
It's harder to control sway when not properly set-up, made more difficult without the numbers. Load 'er up for camping and hit the scales.

I normally increase my TV tire pressure by about 20% over what is recommended (as the minimum pressure) on the door for towing, without exceeding the sidewall max pressure.

Higher tire pressure helps reduce sway.

Sway Question

I suspect that the sway was likely caused by a rut in the pavement. I 405 is not in the best shape and the pavement is often broken and uneven

Whatever the cause, it is impressive to see the truck's electronic anti-sway system respond to it, and immediately correct it before a sway oscillation occurred. That's what the manufacturers have been telling us.

This is likely the reason. limited sway will often be felt on roads where heavy truck traffic has worn the road, even though you often can't see the grooves.

If this remains a brief one time event I would not be too concerned.

Question

Doug,

I thought the system activated after the sway occurred.

"Our trailer sway control feature works with AdvanceTrac® with Roll Stability Control™ (RSC®), using the sensor that measures yaw motion to determine if the trailer is swaying. If necessary, trailer sway control applies precise asymmetric braking or adjusted engine torque to help bring both vehicle and trailer under control.*"

Bob

Check the tow capacity of your truck. You are towing a 9000# trailer with an F-150?

Yes, that is after sway that it kicks in, but also before oscillation.

The first movement from sway isn't normally dangerous, when sway causes oscillation (sometimes referred to as the "hospital wobble" or "death wobble" because of what often happens next) that it gets dangerous.
