Answering Major Trailer FAQs with The Trailer Parts Outlet

Trailers. It’s a big topic. You want to get the best possible tool, and keep it in the best possible shape. Let’s talk about some common FAQs and how to deal with them. 


We collected a few really common FAQs and got the answers together all in one place for you. Remember, you can always check on our FAQ page or contact us for more answers. 


Let’s get into it! 


What’s the Difference Between a Dexter Trailer Axle and a TK Trailer Axle?


A TK trailer axle and Dexter axle are similar in many ways. In fact, up to 7k Axles, all components between a Dexter and TK axle can be interchanged. However, typically a TK axle is stocked with a straight beam, while a Dexter has a cambered beam, which is a slight bend to distribute the load. TKs have one-year warranties while Dexters have five. 


What Should I Know About Wiring Trailer Brakes?


When you get new trailer brakes, each of the new brakes will have two wires for a brake magnet. One wire is for a 12-volt power to the brake magnets and the other wire should be grounded either to the trailer frame or the main trailer ground wire. The wires are not polarized so it doesn’t matter which wire is used for power or grounding.


Understanding Overslung and Underslung Axles


Basically, this term relates to the position of the axle spring. If it’s overslung, it will be over the axle of the wheel. If it’s underslung, it will be under. They’re equally structurally viable, but it does have an impact on the height of the chassis and tongue of the trailer, so factor that into your build. 


Can You Summarize a Maintenance Schedule for the Dexter Axle Trailer?


You can find a complete maintenance schedule for a Dexter Axle trailer on our FAQ section. You’ll notice the brakes get a ton of attention! And they should. 


Let’s number out the basics. 


  1. Brakes get checked every use. 
  2. Tire inflation gets checked weekly.
  3. Bushings get greased every 3 months.
  4. Brake magnets get checked every 6 months.
  5. Brake linings get inspected every 12 months.

How do I know When it’s Time to Replace my Tires?


This is relatively easy to know once you are familiar with the patterns in which tires wear out. Let’s describe a few of them, and describe what causes them and how to fix them. 


  1. Center wear. The tread in the middle of the tire wears flat. It’s caused by over inflation, and you can prevent it next time per tire catalog. 
  2. Edge wear. The tread on the edges of the tire are flattened. This is caused by under inflation, and can be prevented next time by inflation to proper tire pressure. 
  3. Side wear. A flattening on one edge of the trailer.  Caused by overload. Check the rating on your axle.
