If you are hearing a strange, unusual noise coming from your car while you’re driving, it’s possible you may be experiencing wheel bearing malfunction. Wheel bearings are safety-critical components that are designed to sustain axial and radial loads caused by breaking, accelerating, and cornering. A crucial part of your vehicle’s good functioning, problems with wheel bearings need to be addressed quickly to prevent further damage.

Mechanical roller lifters offer higher lift, duration, and overall cam profiles for all-out racing applications. Hydraulic roller lifters have a hydraulic reservoir that offers advantages but limits the maximum cam lobe profile.

In both mechanical and hydraulic roller cams, the remaining valvetrain must be considered to handle the more aggressive lobes of either roller cam. Many pushrods, rocker arms, retainers, and valve springs that are adequate with flat tappet assemblies must be replaced to ensure the proper functioning of the roller tappet installation.

Another important advantage is that hydraulic roller cams require no break-in period — this eliminates any possibility of premature camshaft and lifter failure due to improper break-ins.

Frequently driving through mud, water, or road salt can cause wheel bearing malfunction. Contaminants can get past the seals and enter the bearings, which pollutes the grease and damages the bearings.

As with any car part, the quality of the wheel bearing makes a big difference in terms of how long it will last. Bearings are precision products, and therefore need complex manufacturing processes. Low-quality steel often has poor heat-treating that can spall and wear prematurely and contain hard or soft metal that leads to failure. It is important to consult with a trusted auto mechanic to ensure your car is outfitting with strong, durable wheel bearings.

The first roller cam and lifter were invented back in 1893 by Dr. Rudolf Diesel, for his experimental engine that had a clevis-type cam. Since the days of the Model T, roller cams and tappets have been perfected by racing enthusiasts and are now more popular than ever. Valve lifts and acceleration rates of the cam lobe are far greater with a roller cam and lifter than with a flat tappet design. With newer technology, roller cams and lifters are now broken down into two varieties. From a design standpoint, the roller tappet has an infinite base diameter. A roller cam profile cannot be used with a flat tappet, as the velocity is too high without causing flat tappet lifter failure.Erson Cams offers both solid and hydraulic roller designs, and they’re here to help us explain the difference.Hydraulic Roller Cams and LiftersHydraulic lifters use a pressurized cylinder and piston to maintain a zero-gap valvetrain. The hydraulic roller lifters combine the performance characteristics of a solid roller cam with the reliability of a hydraulic cam.

The first is the initial cost, which is noticeably higher due to the types of materials needed to withstand the higher loads. Also, a hydraulic roller lifter is heavier than the solid option, so they have more inertia for the valve springs to overcome.Mechanical-Solid Roller Cams And LiftersOne of the advantages of a solid roller cam is its ability to provide greater lift and duration profiles for all-out performance and racing. For example, an Erson cam for a big-block Chevrolet application will have maximum measurements for a hydraulic roller setup of .621-inches lift, and a maximum duration of .322-inches intake./330-inches exhaust.This Erson cam profile says it’s best for Pro Street and e.t. bracket racing applications for 540-632 cubic inch engines — no less than 10.5:1 compression, aftermarket heads, with at least 850 cfm carburetor. Erson offers 60 solid roller cam profiles with larger lift and duration than hydraulic roller cam capabilities. Hydraulic roller lifters provide zero-lash advantages, but the solid roller lifter offers bigger cam profiles that a hydraulic option cannot.In both mechanical and hydraulic roller cams, the remaining valvetrain must be considered to handle the more aggressive lobes of either roller cam.

There are a number of reasons wheel bearings might fail. The following are some common causes for wheel bearing failure.

Wheel bearings are sets of steel balls or tapers held together by a metal ring. They enable the wheels to rotate smoothly with minimal friction. At the center of a vehicle’s wheels are hollow pieces of metal called hubs. Wheel bearings fit tightly within the hubs and ride on metal axle shafts, which helps to reduce friction when wheels spin.

The simplest errors, such as using the wrong tools, can cause damage to the exterior or interior of the wheel end bearing. This causes the wheel bearing to fail prematurely. Reusing older accessories, such as nuts, bolts, splint pins, and seals, can also cause wheel end bearings to operate unsafely, which increases the risk of an accident.

How to tell if you have a flat tappetcam

Wheel bearings have an average lifespan of 85,000 to 100,000 miles. If you notice unusual noises, such as humming, growling, or rumbling noises that increase with acceleration, it is important to have your car examined by an auto repair technician as soon as possible. You might start to hear a howling sound during acceleration and deceleration, which can signal problems with gears and differential pinion bearing preload. Accompanied by a rumbling sound, this could mean the bearings are failing to support the gears sufficiently.

Looseness, vague steering or steering wheel vibration and ABS system malfunctioning can also be signs of problems with your wheel bearings. Driving with worn wheel bearings can cause serious damage to your drive-axle and steering assembly. It ultimately can be a major safety hazard. Driving on a bad wheel bearing puts stress on the hub and CV joint, brake system components, and ultimately on the transmission itself. Replacing wheel bearings is somewhat complicated, so it requires professional assistance.

From a design standpoint, the roller tappet has an infinite base diameter. A roller cam profile cannot be used with a flat tappet, as the velocity is too high without causing flat tappet lifter failure.

It is critical for any good car maintenance routine to make sure your vehicle’s tires are balanced. Otherwise, some wheel bearings will endure more pressure and stress than others, leading to damage. Take your car in to a car garage and have a car mechanic take a look if you suspect your tires are imbalanced.

Hydraulic lifters use a pressurized cylinder and piston to maintain a zero-gap valvetrain. The hydraulic roller lifters combine the performance characteristics of a solid roller cam with the reliability of a hydraulic cam.

An automobile accident can cause damage to any part of a vehicle, including wheel bearings. An impact that even slightly dents them can cause malfunction. Potholes, speed bumps, and even hitting curbs can cause damage to wheel bearings that can be diagnosed by an auto mechanic.

Wheel bearings are a critical part of vehicle performance. They are important to the healthy function of any vehicle in that they help the wheel rotate smoothly. Additionally, wheel bearings are necessary for decreased friction caused by various other parts of the drivetrain system. When they become damaged or need to be replaced, serious problems can occur that can ultimately be very costly. Further, when wheel bearings are not replaced by a trained auto mechanic using the proper tools, damage can become even more severe.

Wheel bearings are different from engine bearings in that there is no constant source of lubrication. This means that wheel bearings need to be tight in order to keep away debris, water, and dust. Additionally, they support the entire vehicle’s weight while it is operation, which is the reason they are subject to a lot of wear and tear.

The more frequently you drive on uneven terrains, the more likely it is that your wheel bearings will become damaged and worn. Over time, the steel balls will develop damaged areas that will limit their ability to reduce friction for wheels. At that point, taking your car to an auto repair shop is necessary.
