Your vehicle’s axles play an essential role in moving power from engine to wheels while supporting weight. They do this through various techniques.
Axles are built to support thousands of pounds during normal operation; however, overloading your vehicle could damage its drive axle.
Drive Shaft
The drive shaft is an integral component of an axle, serving to transfer torque between wheels. You will typically find it connected either front- or rear-wheel drive vehicles and often connects directly to their transmission, with four-wheel drive cars also having this connection directly with their differential.
Vehicle drive shafts typically consist of steel, but other materials like aluminum and carbon fiber may also be used depending on their specific purpose. Drive shafts must be durable enough to withstand pressure from an automobile wheel while remaining light enough for turning loads efficiently.
Drive shafts come in both short and long varieties depending on their distance from the gearbox; shorter shafts tend to be used in front-wheel drive while longer ones are for rear or four wheel drive applications.
Understanding all the components that comprise a drive shaft system, including yokes and universal joints, will give you greater insight into its inner workings and help ensure proper functioning of its various parts.
If you hear a clunking sound coming from under your car, this could be an indicator that its drive shaft is malfunctioning and should be addressed as quickly as possible to avoid severe damage to it.
Squeaking can be an indicator of problems with the drive shaft. This may be caused by bearing cap seals being compromised with corrosion or unstable U-joints; either could result in other parts of your drivetrain wearing down faster than expected or becoming completely useless.
Before setting out on any long road trips, it’s wise to inspect your drive shaft regularly in order to keep it functioning at optimal levels and save yourself money over time. Doing this will guarantee a successful experience and save time as well.
The drive shaft is an integral component of an axle and plays an essential role in its performance. If it malfunctions, your car may stop turning altogether resulting in costly repairs or even complete failure of your vehicle.
CV Joint
CV joints are integral parts of an axle’s design, holding it together while transmitting power to each wheel. Though most drivers rarely consider them during their drive, their existence is essential to an automobile’s driving performance.
A typical CV joint consists of a shaft, series of joints, and a rubber boot that protects them from moisture, dirt, and road grime. Furthermore, each of the joints is filled with grease to provide sufficient lubrication during movement.
Cars typically feature outer joints made up of six balls and channels; trucks typically use inner joints with eight balls and channels. Grease is applied to these joints in order to allow them to flex and articulate with suspension movement.
Since joints can flex so freely, power can be distributed evenly among each drive wheel in an indirect manner and effectively controlled by the driver, giving him or her more control of steering and acceleration of their car.
Due to their immense importance, CV joints should always be checked to make sure they’re operating at peak condition. Failing joints could result in the loss of power to all four wheels resulting in decreased vehicle performance and performance issues.
At the same time, it’s also essential that joints don’t protrude at extreme angles – this could cause premature wear on their components and may shorten their lifespan.
Shock loading is another common cause of CV joint failure. This happens when your car’s wheels lift off the ground and land hard after either an intense climb or descent on an off-road trail, usually after experiencing rapid acceleration or deceleration.
Running larger tyres on your car can also wreak havoc with its joints. Their larger rolling diameter and heavier unsprung mass put additional strain on them when lifted off the ground for landing, amplifying any shock loading caused by it.
As with any vehicle modification, installing a suspension lift increases pressure on CV joints as they must operate at increasingly steep angles, potentially leading to premature wear and tear on those components, especially in high-performance cars.
Maintaining regular inspections of your CV joints is the best way to make sure they’re functioning optimally, and may help identify any potential problems before they worsen and require replacement.
Housing
Axle parts are essential parts of a machine’s drive system, acting to connect wheels together, absorb shock impacts from the ground, and support loads or machines.
Axle housings are heavy-duty containers designed to protect and assemble an axle assembly. Their purpose includes protecting its rotating inner parts from impact from ground surfaces while connecting it to its machine host and absorbing impacts from it as well as carrying any weight that might be assigned by its machine of origin. Their size varies according to which machine or load they carry and their specific purpose may change accordingly.
Though most people are familiar with axle shafts and differentials in their vehicles, many don’t realize the complete axle assembly on construction equipment plays a crucial role in its drive system. It generally comprises an axle housing, axle shafts and differential; although exact designs will depend on which machine is being driven.
Many machines rely on axles combined with final drives to generate high torque outputs, and in these instances the axle housing must be designed specifically to support such extra loads to keep everything running smoothly.
To secure the axle shafts and differentials in their proper places, a bracket must be bolted onto the housing to hold them steady. Usually made of steel or chromoly, this piece comes equipped with an aluminized coating for corrosion protection.
The axle tube mounting flange is also included as part of this bracket and designed to keep studs from dislodging under heavy loads.
Axle trusses may help strengthen axle tubes, but their addition won’t do much when an axle housing has already bent. Although these components increase overall housing strength by 30% or so, they don’t address the source of the issue directly.
If you want a foolproof way to increase the strength of your axles, trusses might not be your best bet; opting instead for a heavy duty bolt-in replacement axle assembly could be. These assemblies often boast larger ring and pinion gears, beefier center sections, larger axle tubes, stronger brakes and ball joints as well as more reliable braking mechanisms than factory axles can offer – not cheap but well worth their costs when hitting factory limits and finding yourself dealing with broken parts!
Bearings
Bearings are essential parts of your vehicle’s axle system, helping reduce friction between wheels and hub assemblies and enabling smooth rolling action. They sit between them to help ensure proper functioning.
Axle bearings are typically constructed of high-grade steel and designed for heavy-duty vehicles. Furthermore, these bearings have been engineered to endure extreme temperatures and environmental conditions without suffering degradation over time.
Bearings typically take the form of cylindrical designs that spin around an axle shaft as the wheel turns. C-clips hold these bearings inside an axle housing while some designs provide additional retainer plates to secure the axle in its place.
When replacing bearings, you have two options. Either you can take steps to replace all or just one bearing as one unit, or just the bearing will suffice.
If you opt to replace only the bearing, a special tool will be necessary to extract it from its axle housing. Such tools are readily available at local automotive parts stores.
Be careful when removing bearings; mishandling can result in broken shafts which could prove extremely hazardous, so ideally it would be better left to experienced professionals who know exactly how best to go about doing the task for you.
Once your bearing has been taken out, you should examine it for any signs of wear or damage and, if you detect any, have it repaired immediately.
If you hear noise while driving, it could indicate bearing issues. It is essential to find out whether the sound is coming from one wheel only or can be heard throughout your vehicle.
Bad wheel bearings can produce an infuriating growl, whine or hum that affects steering – particularly annoying while you’re at the wheel! This can make driving all the more frustrating.
Noise pollution may be reduced through braking. Simply give a hard tap or use the brakes a bit more to see if that quietens down the noise.
Your rear axle should always be checked for leaks; failing to do so could cause serious damages and even lead to complete failure of bearings, brakes and differential.
