How To Handle Trailer Sway

When it comes to hauling a trailer you're going to want to make sure safety is your first priority. So we want to make sure you're aware of how trailer sway can occur, how to prevent it, and what to do if it happens.

We know this is a concern for all trailer owners out there so please pay attention to this information and treat this guide as a huge time and headache saver.

Trailer sway can cause dangerous driving conditions and we want to make sure you're out there driving safely, protecting yourself, others, and cargo you are hauling.

Why Does Your Trailer Sway?

Trailer sway can be caused from a number of different reasons. We'll first go over the factors that cause trailer sway then go into how to solve it. Here's a numerical list of what we'll go over.

  1. Too much weight loaded on the trailer
  2. Weight not properly distributed on the trailer
  3. Excessive speeds
  4. Weather conditions
  5. Other large trucks & vehicles travelling beside you
  6. Traveling down steep hills
  7. Worn Tires, Low Tire Pressure

A) Loading the correct amount of weight on your trailer

First of all, whenever you are hauling any type of cargo you want to be sure you know the amount of weight you are able to haul.

A couple definitions are important to know here:

  • GVWR (Gross Vehicle Weight Rating)- The maximum weight your trailer should not exceed with everything loaded; weight of the trailer, all cargo, and any other weight to be accounted for.
  • Payload Capacity- The amount of weight your trailer can haul.

For the purposes of this article we will leave you with these two definitions as we don't want to complicate things.

So in order to determine how much payload you can haul with your trailer, use this calculation:

(GVWR - Weight Of The Trailer) = Payload Capacity.

*You can find the weight of the trailer with the MCO (Manufacturer's Certificate of Origin) after making a purchase with us or by contacting the manufacturer.

We recommend to our customers that your stay within about 85% of your maximum payload capacity to give you some breathing room when hauling cargo. This will ensure your safety and prolong the life of your trailer.

To learn more about weight ratings go to this post here.

B) Weight Not Properly Distributed On The Trailer

To ensure weight is distributed properly for safe driving conditions we recommend loading your cargo so about 60% of the weight is in front of the trailer axles and 40% is behind the axles.

This creates proper weight balance because if too much weight is loaded on the tongue of the trailer then your car will lift off the ground from the front, giving you steering problems. We recommend you have about 10%-15% of the weight on the hitch of a bumper pull and 20%-25% on a gooseneck hitch.

Also, too much weight loaded in the back can cause your trailer to sway and ultimately a whipping motion will take place. So just be sure you distribute the weight of your cargo correctly.

C) Excessive Speeds

Since you are hauling weighted cargo behind your vehicle you are going to want to take extra precaution when going from point A to B.

In this case, slow and steady wins the race. Stay within speed limits and even tone it down a bit to ensure no trailer sway occurs. Hauling a trailer requires you to pay attention, take your time, and practice patience.

Generally once you go over 55 mph you are entering speeds you must take extra precaution when hauling a trailer.

D) Weather Conditions

Heavy winds, rain, sleet, snow, ice. These can all be hazards conditions and can result in your trailer swaying. Remember, always use caution and good judgment when you know you're going to encounter less than ideal weather.

Pull over, prolong your trip if you have to, safety always comes first. If you are caught in the weather, drive with both hands on the steering wheel at safe speeds.

E) Other large vehicles driving beside you

Most of us have experienced driving past a large vehicle such as a tractor trailer, bus, dump truck, etc. Due to the size of these vehicles that create strong wind drafts that can pull your vehicle in or out.

Ultimately, if not controlled properly this could cause your trailer to start to sway. We recommend avoiding making passes when you can and staying at a constant and safe rate of speed when traveling beside larger road vehicles.

F) Driving downhill

Driving downhill will cause you to increase speed and the weight of your trailer to push against the back of your vehicle. These two factors may result in some sway depending on the circumstances.

To prevent this before going downhill reduce your speed and start braking periodically going down the hill instead of all at once when panic sets in. Always be mindful when pulling a trailer downhill.

G) Worn Tires, Low Tire Pressure

The quality of your tires is another determining factor of how steady your trailer will pull. You'll want to replace your tires periodically. Also, make sure your tires are filled with the correct air pressure.

If you need any assistance replacing your trailer tires or servicing them, we are able to take care of your needs here at our shop! Give us a call.

How to deal with trailer sway?

Here is a 6 step process if you start to experience trailer sway.

  • Remain Calm, be aware of your surroundings
  • Slowly decelerate by taking your foot off the gas, Don't brake or speed up.
  • Firmly grab the steering wheel with both hands and keep straight, don't over correct.
  • Using reasonable judgment, use your brake controller lever to only apply brakes to the trailer
  • Wait until you have come back down to a safe rate of speed or steady driving balance
  • Find a place to pull over. Check that your weight is distributed properly, tire pressure is correct. Make sure all your cargo is secure

What can you buy to help prevent trailer sway?

Here at NC Trailers we offer mechanical solutions to this problem. There are two parts for sale to help prevent trailer sway. The parts we offer are:

  1. Curt Weight Distribution Hitch
  2. Curt Sway Control Kit

The weight distribution hitch works by leveling out and distributing the weight of the trailer across the vehicles and trailers axles.

As we discussed above, there is importance in properly distributing all your cargo weight properly and this hitch can help you do just that.

The sway control kit is then attached to the weight distribution hitch to prevent lateral movement of the trailer. This will keep your trailer driving straighter down the road with less worry of trailer sway happening.

The sway bar uses a material like that used in brake pads to provide the necessary resistance while still allowing your vehicle to complete proper turns with your trailer attached. The sway control mounts onto the frame of your trailer and connects to the vehicle's ball mount using a separate trailer ball from that used for coupling the trailer.

Therefore, the combination of these two parts helps solve the problem of improper weight distribution and lateral movement of the trailer. If you're interested in buying these from us just click the links in the list above. If you need help installing them, we can help you out there too.

Conclusion

We hope this article has given you more solutions when dealing with trailer sway. Again, we have gone over a list of reasons trailer sway occurs and what to look for to prevent it. In the event you experience your trailer swaying, make sure you look over and remember our 6 step process on actions to take.

Also, you can buy our two parts to give you more insurance and peace of mind when hauling your trailer.

Had the pleasure of buying our first trailer for our new business from them this weekend. And let me say I can’t say enough about this company. From the first call with Donna, till we drove off the lot hooked up, they were absolutely amazing! Their inventory is intensive yes, but the customer service is extraordinary! Our purchase experience start with a transfer to Zach who was welcoming and extremely knowledgeable! Shancie took care of the financing and made everything so easy and simple, and Tammy was fast with our paperwork! Noah and Ryan went above and beyond for the install and hookup of all the accessories we choose! These folks are the best around and hire the most wonderful crew! Highly recommend them for any trailer purchase or service needs!

I would like to take a minute and recognize several people at NC trailers. From the start it was Zach & Sam in sales which went above and beyond the process of helping me pick the correct trailer and helping me complete all necessary paperwork when I was literally 1800 miles away driving down the road.

Shanice in financing made financing the trailer simple and quick, and behind the scenes Tammy in tag/title department was doing her magic so it all came together as one cohesive unit the day of picking the trailer up.

Speaking of picking up the trailer, Ryan & Noah truly went above and beyond expectations working in the pouring rain, while not compromising standards of making sure everything went smoothly and that I was hooked up correctly while taking the time to fully go over every aspect of the trailer and how to hook and unhook the trailer.

Tyler in Service & Parts was very helpful with information regarding the Gooseneck hitch for my next trailer.

Thank you to each Team member of NC trailers. I HIGHLY recommend this company to anyone needing a trailer.

So, if you need any type of trailer, accessory or even a repair, NC trailers should be your First and only stop. They truly make you feel like Family and the trailers are rated top in the Industry and priced very reasonably.

Head on over to NC trailers and get your trailer today. Tell them Mitch with a “M” not a “B” sent you, and you should receive an extra smile or two.

I have to say I had great experience with the staff at NCtrailers in Thomasville, NC. The staff up there were amazing. I had the pleasure of being David’s first sale for his new career dealing in this type of equipment. He has had many years in sales and it shows but he decided to venture into a new atmosphere of sales. Working through the contract side of things Shanice was very thorough and was able to give me all the details I needed. She was so inviting and made you feel comfortable through would could be a stressful process.

Tammy was a sweetheart with the tag and title paper work and talked me through all the necessary links and info I would need to setup the last little bit of info.

Ryan and Noah had me all hooked up and ready to go and even took the time to help me find a short in my connection on my truck so I would be comfortable knowing all the lights and everything worked properly on the new trailer.

All in all I had a great experience with the entire staff from parts to sales to service. I will most definitely be recommending them to anyone I know for their trailer needs.

Now wish me luck on my lawn care company venture.

After searching many sites, I settled on calling NC Trailers of Thomasville, NC. Zach was very helpful over the phone answering my questions. After I decided on a trailer I drove 3 1/2 hours to arrive at their location only 30 minutes before they closed. They didn’t mind my late arrival or staying to complete the sale. I changed my mind on the trailer I wanted and Shaun was very quick to redo all the paperwork for the sale. Noah was also helpful in going over the trailer with me and answering questions I had. And thank you Tammy for saving me a trip to NCDMV, at NC Trailers they can do your DMV registration and you leave with tags already installed. The trailer pulled smoothly all the home.

This company was great! Zach showed us great options, and helped us pick the perfect trailer for our needs. Shawn explained all of the extra packages we could add to it, and finalized the contract. Tammy did a great job at making sure we had our title, tag,and registration taken care of. And, Ryan and Noah got us hooked up and ready to go. Because they have an on-site parts and service department they were able to install the needed brake controller the our truck wasn't equipped with. Wonderful place. Will definitely recommend!
