  • Axles Hubs and Bearings

    Replacing RV Axle Hubs And Maintaining Your RV Wheel Bearings

    Many RV parts and accessories or components require routine inspections or RV care servicing before embarking on a great vacation adventure. A wheel bearing failure is one of the leading causes of RV roadside repairs. Not only it is an inconvenience but it can cause a very serious situation that can cause an accident, serious injury or even death. To determine if there are compatible axle hubs and bearings to replace your current hubs to a more standard size, you will have to take several precise measurements on the spindle of your axle. Experts suggest to use a set of dial calipers to obtain these measurements. When you're purchasing a trailer hub assembly on a trailer supply or trailer parts superstore, there are some important information to know in order to make the correct selection. Wheel hubs vary in dimensions based on the si­ze of the trailer wheels and the bearing load. As for wheel bearings, you just simply replace them if they are in bad shape.

    Before you buy in a RV parts store, you should:

    • Find out how many stud holes should be in your hub. Hub assemblies usually comes with either 4 or 5 holes around the circumference.
    • Most wheel hubs have bolt hole diameters between 4 and 6 inches, divided into half-inch increments. To obtain that figure, measure from the center of that large bolt hole to the center of a stud hole, and divide that number by two.
    • Know the inner and outer bearing size. Most of these bearings have a reference number engraved on them that indicates their diameter or part number. The dealer you buy the hub from should have that chart available, or you can find it in any RV supply store or ordering RV parts online.

    Once you have your wheel hub assembly with the correct specifications, it's time to install or have a pro install your bearings. You will need to measure the seal, inner bearing, and outer bearing. When repacking bearings, they should always be cleaned with a proper bearing cleaner and wiped dry, then thoroughly inspected by looking for rough spots or pitting on the surfaces and for signs of overheating and wear. When cleaned, they should spin freely and have no rough spots. In most cases, an RV or motorhome is parked in the off-season. Without proper scheduled RV maintenance, condensation can be a factor. Rust can form inside the bearing assembly, and when travelling the rust will start to scratch the bearing roller surface, which will cause excess friction and heat.


    This will eventually lead to fatigue, disintegration of the wheel bearing and welding of the center of the bearing to the spindle. The axle and brake assembly also will be destroyed in many cases. Even if you are not a pro doing this kind of stuff, a great tip is to always carry a complete wheel bearing kit or spare with all the parts and tools required to do a roadside repair. That way you have the parts readily available for a qualified technician anytime and anywhere to get you safely back on the road. And if you are confident, you can do the wheel bearing repack yourself.

  • Braking

    Why You Need a Supplementary Braking System for Your RV

    Needing a separate braking system installed for the trailer may come as a surprise for novices who are towing a trailer for the first time. Yes, the RV will indeed have a braking system of its own, but when you’re towing a trailer behind it, it’s recommended that you install another braking system on that trailer. This will ensure that the towed vehicle will brake accordingly and in conjunction with your RV, saving them from being damaged unnecessarily.

    There are basically two kinds of braking systems – the ones that can be permanently installed on the towed vehicle, or those that are portable and can be installed and removed as required. The permanent ones will need to be installed by a professional, but after that, you can easily hook up your RV to the towed vehicle in just a few minutes.

    These are also called supplementary braking systems, and if you’re planning to tow anything with your RV, it is absolutely essential that you install one on the vehicle to be towed before going anywhere. The most important reasons for installing a supplemental braking system will be safety, minimizing stress on both your RV and the towed vehicle, and maintenance.

    Let’s talk about safety reasons first. It’s actually pretty straightforward: using a separate braking system on the towed vehicle allows you to enjoy a more controlled driving and towing experience. More control over the towed vehicle means you’re reducing the danger of having thousands of pounds at your back going astray or not stopping when your RV stops.

    Installing a supplementary braking system also puts less stress on the RV and the towed vehicle. Keep in mind that even though your RV can tow 5,000 to 10,000 lbs. of vehicle, it’s not really designed for stopping anything behind it that weighs that much. Some may insist that their motor home’s braking power is much more than the weight of the vehicle being towed, but using your RV’s brakes for this purpose will cause unnecessary damage and stress to its brakes. It’s much better to use supplemental brakes instead.

    Another thing to keep in mind is that most, if not all, RV manufacturers are placing weight limits on the vehicle and loads that their RVs should be towing without using supplementary braking systems. These recommended weights range from 2,000-3,000 lbs. depending on the RV. Exceeding that limit will not only put your RV at risk of being damaged, but your warranty will also be voided if you don’t follow the specifications set by the manufacturer.

    Brake Buddy Classic Breakaway System – This system will automatically engage the brakes upon sensing that the towed vehicle has separated from your RV, bringing the vehicle to a controlled stop.

    Brakebuddy Digital Classic II – A portable braking system that works via an electronic decelerometer. The system applies pressure on the towed vehicle’s brake pedal through air cylinders and also informs the driver that the brakes are being applied.

    Even Brake System – The brake system that ensures even, proportional braking for your towed vehicles. This system will automatically apply the brakes of the towed vehicle at the same time and at the same intensity as the brakes of the RV.



  • Handling and Suspension

    A Basic Guide to RV Handling and Suspension Systems

    Whether you’re going on a trip down the beaten path or opting for an exciting off-road adventure, one of the most important things that RV owners always look for is a comfortable, smooth ride. When you’re out shopping for an RV, you tend to look for lots of space, color options, room layouts, and the furniture. But when you’re actually driving that RV, the aesthetics will always take a backseat compared to how comfortable the ride is.

    It doesn’t matter whether it’s your first time going on an RV trip or you’re already a veteran; sooner or later, you’re going to have to pay attention to your RV’s handling and suspension. If you’re a beginner, this guide will put you on your way to understanding the different RV suspension types.

    First off: your RV’s handling and suspension system will be the same as any other vehicle’s. It will basically consist of the tires, springs (or any other shock absorbers), and any other mechanisms that connect your RV to its wheels. This system will control how your vehicle and wheels work together to provide a smooth ride, if configured properly.

    One of the most common type of handling and suspension systems involve the use of coil springs. These are found in all types of vehicles, including RVs, trucks, and cars. The coil spring system essentially uses metal coiled springs that will help cushion the impact from the road. It’s the most common but not the most comfortable.

    Another popular but better choice for your RV’s suspension would be leaf springs. Leaf springs consist of a single or several layers of slightly curved pieces of metal. These springs are designed to bend along with the bumps on the road, and are available either for highway traveling or off-road rides. Leaf springs are incrementally better than coiled springs, but not by much.

    Torsion bars are also a popular choice for RV enthusiasts. These are round metal bars connecting your RV to a control arm, which allows the torsion bars to twist and bend along with the road to help provide a more comfortable ride. These are great for RVs with a low center of gravity, plus they can be used in conjunction with other handling and suspension systems. Torsion bar systems can also be upgraded or modified depending on what the owner needs.

    The best (and therefore the most expensive) handling and suspension systems for RVs involve a combination of air bags or air springs. These are excellent for cushioning any road bumps.

    A typical system would consist of four or eight air bags or springs working together with another suspension type. These systems will provide the “cushiest” ride among all the others, but will be among the most expensive.

    Loadlifter 5000 Leaf Spring Leveling Kit – This air suspension kit is designed for up to 5,000 lbs. leveling capacity, and will help keep your vehicle from swaying, squatting, and bottoming out.

    Heavy-Duty Air Systems Dual Electric Air Command – Provides front-to-rear or side-to-side leveling support, controllable via a modern electrical control system. Dual gauges and a heavy-duty compressor will help you keep track of air pressures and inflate the air springs individually as needed.

RV Suspension Maintenance

When it comes to RV maintenance and the components while trailer and fifth-wheel suspension systems are frequently neglected, a proper function and well-maintain suspension has to ensures a safe and enjoyable towing experience. The latest technology on suspension systems serve as attachment points between the trailer’s axles and frame when traveling over bumps and holes and these suspension system keeps the tires in contact with the road while absorbing and damping the jolting effect road-surface imperfections can cause breakdown along the road. Doing a general examination to onto if leaning toward one side or does one tire sit higher in the wheel well than the others because tires on one side these conditions might be caused by the contents of the trailer being poorly distributed of a tandem suspension the same distance apart as the tires. An indicate broken or worn suspension components often move excessively while being towed causing clunking grinding or creaking noises into swaying which also indicate problems with the suspension system.


RV Suspension Systems

Most RV suspension systemsuse leaf springs to cushion the ride because leaf-spring setups are mechanically uncomplicated and inexpensive and having a main spring with eyelets at each end progressively shorter springs fastened by a center bolt because the length, width, contour, thickness and number of leaves determine how stiff the leaf spring is to support the weight. It’s been used in suspension systems for centuries but modern manufacturing techniques have greatly increased their strength and reliability as well as how smooth they do the job.


RV Brakes and Bearings

RV Brakes and Bearings also require service which recommended maintenance schedule like the repacking bearings every year because if brakes have no automatic adjustment it should be adjusted every three months and linings should be visually inspected because annual service should include inspecting the running gear that include suspensions. Driving a towed vehicle and RV into the scale with all passengers, supplies and equipment as for a typical trip will take a weight reading as each axle or axle group comes into the scale and the first reading will be the load on the tow vehicles front axle, the second one is the total tow vehicle weight including the trailer tongue weight that gives the loading on the tow vehicle rear axle combined towing weight carried by the trailer axles.


Electric Brake Controls

The electric brake controller is a necessary safety feature when towing a heavy trailer and all of the braking needed to stop the entire rig may be asking for trouble that expecting your tow vehicle to provide. Most electric brake controls applied the amount of braking needed depending on speed because of the pressure applied to the brake pedal and the rate of deceleration and if not adjusted properly the trailer brakes may grab, skid or not working at all. Electric brake controls are installed in tow vehicle which applies the trailer brakes automatically when the tow vehicle's brakes have been applied and the trailer brakes may need to when the weather or weight of the trailer load changes with the power knob adjust on the brake controller because the reduction in braking power may be needed when roads are slippery.
