Ensure that all force is shifted properly from your driveshaft to the wheels. Cover your constant velocity joint with quality CV joints and boots.
Have you ever wondered how you can move your arms and legs? Well, moving those body parts are made possible by something called joints. Your car also uses joints too, if you must know. And just like your arms and legs, these joints allow some parts of your car to move to achieve a smoother operation. One of these joints your car uses is called the CV joint.
In order for your body joints to function, a protective layer of muscle is applied. That's the same way with your car's CV joint. In your CV joint's case, this protective layer is called the CV joints & boots. This auto contraption is made from high-impact rubber to ensure a smooth flow of torque from one driveshaft to the wheels. This is done without sacrificing the speed of the driven shaft inside your car. The end result of this process is a smoother and more efficient overall operation of your car.
If there's something wrong with your car's CV joints & boots, you need to replace them as soon as possible. If your car has damaged CV joint boot, power from the driveshaft won't be transferred efficiently to the wheels. Basically, your car loses power and burns more fuel. So better take the first move and have it inspected by a mechanic right away.
Finding the Best CV Joint Available
The CV joint is what allows quality cars like a luxury sedan to turn on a dime, swerving tightly around a curve with amazing precision and control. It's the control velocity (CV) joints and other CV-related components inside your car make such amazing vehicular maneuvers possible. When your CV system breaks down, the repairs can get quite expensive. Thankfully, ecommerce and online automotive sites tend to have an extensive collection and selection of CV joints available at costs that are much lower compared to buying offline through an auto body or spare parts shop.
Considerations When Shopping for a CV Joint
- Always Buy Brand New CV Joints: When buying used CV joints for the sake of saving money since they're cheaper, it comes with the detriment of always checking the outward condition of the joint. It's protected from the elements care of the CV boot, but it's much better and more cost-effective to get an aftermarket OES CV joint and CV boot without much mileage on them compared to a refurbished or salvaged part that might be splattered with oil and/or dirt.
- Pay Attention to the CV Boots: The toughness of your CV boots that come along with your CV joints dictate how long your purchase will last you. They're the covering that will bear the brunt of the outside stress, wearandtear, and whatnot of your CV joint while at the same time shielding it from debris, oil, dirt accumulation, and damage as long as it lasts. The boots should come in one piece and without holes or deformation on it.
- Look for Durability Against Interior Stress: Pay attention to the ratings and reviews of the CV joint you've decided to patronize. If the reviews for the joint particularly praise it for its ability to handle interior stress, then it's a must-buy for sure. Some applications don't require interior stress management, like in the case of Rzeppa joints. However, when dealing with shafts like the Cardan shaft and its usage of U-joint parts and CV shaft parts, your CV joint should be able to handle stress at certain angles.
- Check the Inner Race, Cage, and Outer Housing: The CV joint is able to provide a quieter, smoother ride with greater angle capability thanks to the excellence of its primary components. The outer CV joint's drive gear is its inner race that applies torque from the CV axle shaft to the ball bearings, which are centered by the cage. The torque is then transferred to the outer housing, which takes on different shapes and designs depending on its manufacturer.
- Learn about CV Joints versus Universal Joints: CV joints are ideal for automotive applications because they're more efficient at what they do when compared to universal joints. The best CV joints out there are capable of wear reduction that's not present in the more wear-susceptible standard universal joint type shafting that CV joints replaced in modern car design. These joints also isolate the drive and driven units, which reduces the amount of induced noise.
The Bottom Line
In a nutshell, the best CV joints are the joints with quality interior components (the inner race, cage, and outer housing), offer superior interior stress mitigation, provide the toughest of CV boots, and are undoubtedly brand new (as opposed to used joints with a lot of mileage on them). If you decide to buy refurbished or used CV joints, make sure that their outward appearance and interior components are still in excellent condition so that you won't end up with a dud joint.
