FAQ’s Answered About Trailer Hitches

FAQ's Answered About Trailer HitchesQuality trailer service and repair start with knowing the right questions to ask. McFarlane Trailer Sales receives questions about trailer hitches often, so let us help you with some answers to common questions about them.

What Size Ballmount Do I Need for My Trailer Hitch?

This will depend on the overall weight rating of your trailer. Trailer hitches are tested and rated for specific ball mount sizes. The receiver size will be anywhere from 1 1/4" to  3" within the five classes of weight ratings. The heavier the weight rating, the larger the ball mount. The weights are then broken down into the following categories:
  • Class I: 2,000 lbs
  • Class II: 3,500 lbs
  • Class III: 6,000 lbs
  • Class IV: 12,000 lbs
  • Class V: 14,000 lbs 

What Is a Brake Control?

Electric brake control takes power from the tow vehicle and supplies it to the trailer's brakes. A small control box is installed underneath the driver's side dashboard. When the driver depresses the brake pedal for the tow vehicle, the electronic box sends an electrical current to the trailer brakes.

Proportional Brake Controls 

Proportional or inertia brake controls get a read on how quickly the tow vehicle is stopping and send the same amount of force to the trailer brakes. A brake pedal switch is activated by a pendulum circuit that applies the correct amount of voltage to each brake.

Time-based Brake Controls

This method requires the user to set a predetermined amount of power in the brake box. When the driver hits the brake pedal, there is a time delay before the trailer brakes are engaged. You can be traveling at any speed, and the trailer brakes will engage in the same way every time.

Are Safety Chains Required When Towing?

Yes. Laws require you to use chains or cables when towing. In the rare event that the trailer becomes disconnected from the ball (on a bumpy road), the chains will keep the trailer connected to your truck. Otherwise, your trailer will be loose on the road, creating an extreme safety hazard. Avoid costly trailer service and repair by using safety chains.

What Is Trailer Sway?

Trailer sway happens when the tongue is not heavy enough to create a downward force on the hitch ball. If the weight in your trailer is distributed unevenly, you may experience the trailer bobbing and weaving behind your tow vehicle.Test this by loading a trailer and gradually increasing your speed on the open road. Watch the behaviour of your trailer closely. If it rocks from side to side or has trouble staying in the lane, park and adjust the cargo so its heaviest part is closer to the tongue. If this doesn't work, consider buying a weight distribution system for your trailer.

How Do I Measure My Trailer Ball?

Four important measurements include ball diameter, shank length, shank diameter, and the trailer hitch ball load rating. Start with the diameter of the ball, using a tape measure or ruler. Then measure the ball shank size from the bottom of the base to the end of the threads. Finally, measure the thickness of the base. Make sure this all matches up with the weight rating.

Summer Maintenance Tips for Your Trailer

Summer Maintenance Tips for Your TrailerAs spring comes to an end, it's time to make sure that the wear and tear from winter's cold and spring's rain will not affect your summer hauls. Pay special attention to your brakes, tires, grease, and suspension, as these will be the most likely to break down if not treated with care. You can avoid a large headache and expensive problem by prioritizing trailer service and repair before the summer gets into full swing. 

Brakes

Think back to the last time your brakes were replaced. Has it been more than 12 months? If so, you should definitely consider replacing them, for safety reasons. Also, think about how much wear and tear has gone into your brakes during the last year. Have you been in a lot of traffic, therefore braking more frequently? Have you been descending steep grades? Measure the thickness of your brake pads and determine your next steps. Usually, you can hear the squeal or grind when you apply your brakes, but sometimes the road noise prevents you from getting this warning. As always, don't wait until you know there is a problem. Proactively prevent problems before they become major issues. 

Tires 

Tires are expensive, but a necessary expense to keep your fleet operating efficiently. Walk around your trailer and check the depth of each tire tread to ensure the tires are not going bald. Also, check the pressure. A visual inspection of rocks, thorns, nails, screws, and other punctures may prove wise here as well. Having a blowout on a highway in the heat of summer is no one's idea of a successful haul.Keep in mind that some small punctures can be patched, while others may require the tire to be replaced. If you need to replace a tire, consider also replacing the other tire on the same axle, to ensure that the two tires wear evenly. If the expenses catch you off-guard or worry you, just imagine how much more worried and stressed you will be if your entire rig breaks down due to something that you could have prevented. Remember the old adage: an ounce of prevention is worth a pound of cure.

Grease 

Gears and hydraulics simply have to operate smoothly if you are to stay in business. If the gears grind together, you will be facing a major mechanical malfunction. Remember which type of grease you originally used, and apply the same. New applications of the same grease type will wash out the old, dirty residue and keep your trailer operating efficiently and safely. 

Suspension

In order to keep your ride moving along smoothly, and to ensure the stability of your load, all high-impact elements of your suspension system should be inspected. Visually assess any fasteners, welds, and overall levelness of the trailer. Ensure that all bolts are secured where they should be and that there is no component interference with the pivot connection. Air springs, axle connections, and shock absorbers should all be without bend or rust. If any fasteners are loose, tighten them to the correct torque specifications.
