The Function of Jockey Wheel

     From the above picture, we can see clearly the supports under the caravan A-frame. The bolted-on jockey wheel has been moved off to one side to make space for the weight distribution hitch. A wheel cradle under the jockey wheel stops the van moving sideways unexpectedly. The stand under the A-frame opposite the jockey wheel provides very firm support for the front end of the caravan and reduces reliance on the jockey wheel. Both supports under the front end give more flexibility in setting up the van.
       When jockey wheels are subject to a great deal of dust and road grime, the replacement is needed. Foreign particles find their way into the mechanisms of the jockey wheel and in particular cause corrosion and pitting of the ball race and its cup washers – components that take the load when you wind up the front of the caravan. This wear results in a grinding, rough feel as you turn the handle. By replacing the worn or pitted ball race, the jockey wheel can be made to feel like new again. You might also consider a way to keep moisture out of the mechanism if the device is left outdoors for prolonged periods.

The Usage of Wheel Bearings Protector

       The wheel bearings protector is a small metal cap which fits into the center of your trailer's wheels. It is able to block dirt and moisture from entering your trailer's wheel bearings, helping make the bearings last longer. Trailer bearings stabilize the trailer's wheels and keep the trailer riding smoothly. The bearing protector is used to keep the trailer bearing free of foreign matter, which can interfere with wheel balance and revolution. It also provides an air-tight seal for the bearings.

       Since it’s an important part to keep wheel bearings from damage, it’s necessary that you know how to remove or install the wheel bearings protector. The following steps are the instruction of removing the wheel bearings protector when you need to check the condition of wheel bearings and brakes:

1. Lower the front of the trailer by lowering the tongue jack until the tongue is nearly resting on the ground or the jack bottoms out.
2. Place two jack stands underneath the rear frame of the trailer, which is about halfway between the rear of the trailer and the trailer axle.
3. Raise the front of the trailer.
4. Remove the lug nuts from the wheel using an impact wrench or lug wrench.
5. Insert a flat blade screwdriver between the wheel hub and the raised edge on the bearing protector to pry the bearing protector out of the wheel hub.
6. Pull the bearing protector off with your hand.

The Function of Ball Mount in the Towing System

       Do you know what ball mount is? If you plan to tow, you'll need to select the best components to make up your entire towing system. Accessories like Hitches, receivers, ball mounts and hitch couplers are the main components that make up a complete towing system. Some hitches are used for heavy-duty and commercial use. Some even resemble those seen on tractor trailers.
       Choosing the proper ball mount just like choosing almost any other towing accessory. Safety is the most important thing to keep in mind. Selecting the proper ball mount involves taking some measurements from both your tow vehicle and the trailer you plan to haul. First of all, measure the height of ball mount. Then, determine ball mount size. In addition, there are some reminds for you to know before you making choice.

1. Some ball mounts have a drop on one side and can be turned upside down if a rise is needed.
2. You can purchase a ball mount that is straight, without a rise or drop, if no adjustments are necessary.
3. Measuring from the wrong location on the ball mount for the rise or drop can make your trailer sit out of level when attached to the ball mount.
