Axle Housing Parts

Axle Housing Parts are integral components that enable power transfer from your engine to the wheels, whether for cars, trucks or even race vehicles.

There are a variety of front and rear axle designs and options available, each designed specifically for optimal performance and heavy horsepower applications. A performance heavy duty design will increase strength for handling higher horsepower applications as well as making setup easier.

Rear Axle

The rear axle of any vehicle is an integral component, transmitting power from its differential to its driving wheels and maintaining distance between them and their body while bearing weight.

Rear axles come in many varieties, from semi-floating to full-floating models. Each type varies in terms of its strength and functionality.

Full-floating axles may be better suited to heavy vehicles than semi-floating axles and have greater torque handling capacities than semi-floating axles.

Full-floating axles feature two bearings which enable it to freely “float” in its differential. These types of axles are commonly found on trucks and SUVs as well as mid-sized four-wheel drive vehicles.

Three-quarter floating axles are an increasingly popular type of axle design, as they offer greater wheel alignment accuracy and can help control side thrust forces.

When your car’s rear axle begins making unusual sounds or is no longer performing as efficiently, it could be time for repair or replacement. Replacing it early could save money in repairs in the long run while giving your ride an updated, enjoyable feel.

There are various causes that could result in the damage or wear-and-tear of a rear axle, including leaky axle seals, squeaking U-joints, and lack of lubrication. All these issues could potentially do severe damage to your vehicle if left unchecked – so make sure that they’re regularly inspected.

Front Axle

The front axle is an essential component of any car. It carries its weight while helping with steering and absorbing shocks caused by road surface irregularities; additionally it also absorbs torque created during braking processes.

Front axles consist of four primary components: beam, stub axle, swivel pin and track rod. They are typically constructed out of carbon or nickel steel for durability.

A stub axle connects the main beam to the vehicle’s front wheels by means of kingpins and has two taper roller bearings to support its main beam.

Dead front axles do not turn, yet still provide sufficient rigidity and strength to support the weight of their vehicles. Usually composed of 0.4% carbon steel or 1-3% nickel steel alloys.

These axles take the brunt of vehicle weight when bent, while being capable of withstanding both vertical and horizontal loads due to being constructed as I-sections with circular or elliptical ends.

When the axle is configured in this way, its load-bearing capacity can be more evenly dispersed, making it suitable for heavy vehicles that frequently travel over rough roads.

As well as stub axles, there are various other forms of front axles besides stub axles. They include Elliot type axles (both forward and reverse elliot types), Lemoine types, and their reverse counterparts – to name just some of them.

Axles are integral parts of any vehicle, but replacement isn’t often necessary. In such instances, if the front axle becomes damaged or malfunctioning it should be addressed quickly in order to prevent further problems with performance and reliability.

Hubs

Hubs are essential components of your vehicle’s steering, suspension, and braking system. They serve to connect axles, wheel bearings, steering knuckles and turn your wheels, while supporting its weight while steering in all directions.

Hub assemblies can be assembled from various materials and come in various styles to suit various industries. Their designs may differ according to industry needs; however, all hub assemblies share common components like bearings, seals, bolts or studs and dust caps.

Hubs are typically made of either steel or cast metal and feature splined teeth that mesh with those on an axle shaft they are bolted to, enabling it to spin with any wheel it is attached to, providing driving force as it turns.

Hubs are integral components in many industries, from agriculture and construction vehicles to transportation vehicles. Their designs and materials vary depending on the field in which they’re used; all feature tapered roller bearings in their centers for rotation support.

Two-piece hubs are an increasingly common sight on older cars and trucks. Though more stable overall, their weaker construction can compromise splined teeth on axle shafts resulting in damage or ruin of axle shafts.

Hubs can do much more than support the weight of vehicles: they also act as switches, sending data packets on predetermined paths depending on attributes (MAC addresses) within them.

Hubs can be relatively slow networking devices due to using Half Duplex communications – where only one device at a time can speak out – and are also often vulnerable to collisions that disrupt traffic flow temporarily.

Bearings

Wheel bearings are an integral component of axle assembly, enabling wheels to freely spin in their hub while protecting it from damage.

A typical wheel hub assembly consists of inner and outer bearings held together with cages that encase them, designed to transfer both radial and axial load without creating excessive friction.

Roller and ball-style bearings are among the most commonly used. Tapered roller bearings, in particular, offer excellent support for horizontal and lateral loads due to their slightly conical bearing surfaces, making them an excellent choice when thrust is required as they can accommodate both directions of force.

Although there are various kinds of rolling bearings, each variety offers distinct advantages. Strength and mobility determine how much load a bearing can bear while alignment factors determine its suitability for specific vehicle applications.

Before making the decision to replace bearings, look out for signs of wear like play in the wheel and unusual noises like grinding. Jack up your car and move the suspect wheel assembly from side-to-side or consult a reliable mechanic for diagnosis.

Some types of bearings require regular service in order to operate efficiently, while others can go longer without needing servicing – examples being fluid and magnetic bearings as well as rolling-element bearings with sealed components to keep dirt out while keeping grease inside.

Commercial truck and trailer bearings are usually designed to withstand harsh environments, including abrasion, corrosion, heat and shock from potholes or other obstacles.

Seals

Seals prevent fluid leakage by keeping gear oil and other fluids within your car’s drive train from escaping and dirt or debris from getting inside its diff or tranny. They also provide additional protection from contaminants getting in.

Axle seals come in various sizes and types depending on the make and model of vehicle they’re fitted on; their primary purpose remains the same though – to keep fluids within your drive train safe.

Some seals are designed to withstand high temperatures and constant wear, and this can be achieved using various compounds like HNBR (hydrogenated nitrile butadiene rubber), polyacrylate or even PTFE.

Other seals are more straightforward, comprising of a metal retainer with an elastomer seal lip that fits easily into shaft bores and adheres securely to shaft surfaces.

Dependent upon the material being used, this type of seal can either be hardened or lubricated depending on its composition. This feature is vital as a dry or damaged seal lip may overheat and become brittle over time, leading to its premature failure.

These seals can be quickly and easily installed by either a professional mechanic or home DIYer, provided they are installed correctly. Failure of installation could cause your shaft to slip, leading to extensive repairs.

Axle seals are used on vehicles’ front, rear, and all-wheel drive axles to prevent fluid leaks as well as foreign objects entering their differential or tranny which could accelerate wear on gears and cause premature wear on them.

Before installing axle seals, they should be cleaned and lubricated properly to reduce leakage during driving. They should also be installed squarely against the axle shoulder without leaving any rough surfaces exposed, for optimal performance.
