You could be wondering how CV joints and car axles are related if you've never driven before. Simply said, inner and outer CV joints distribute torque from the gearbox to the driving wheels by connecting the vehicle axles to the front wheels. The CV joints are flexible, allowing them to move up and down with the suspension or side to side while spinning the wheel, resulting in a smooth transmission of power to the wheels.
When
looking for garages
in Reading to book your car for a routine service or repairs, ask the
car mechanic for a full health check of your vehicle to see if any parts
are failing and need immediate attention or will need to be repaired or
replaced soon.
A
failing CV joint generally has immediate repercussions, and power is no longer
delivered from the engine to the tyres, making your car undriveable. As soon
and safely as possible, pull off the road. Look for car services near me
online and call the garage to see if they have any availability for your
vehicle. If this is the case, contact your recovery firm and inform them of
your breakdown. You may also contact your local mechanic and arrange for your car
to be recovered to their garage for repairs.
So,
how do you know if your cv joints are bad? Here are some CV joint symptoms you may begin to notice:
1. Clicking sound - This sound is most
commonly heard while making quick turns at low speeds.
2. Clunking sound - When accelerating or
suddenly letting off the accelerator, a clunking sound can be heard.
3. Grease leaking - Because both joints are
covered by a grease-filled rubber boot, any tear or fracture in the boot might
cause grease to flow out and coat the tyre, steering, and suspension
components.
4. Excessive vibration - If the CV shaft is
bent, you'll experience excessive vibrations when driving, which will get worse
as the speed rises.
Check MOT
status
and get any CV Joint or CV Boot problems addressed beforehand if you
experience any of the above symptoms. The reason for this is that a ripped or
split CV boot, as well as a damaged CV joint, will fail the MOT test.
Vibration Can Be Caused by Damaged Inner CV Joints When Accelerating
Inner
CV joint deterioration causes acceleration vibrations and is difficult to
identify since the damage is so subtle. Only when the inner CV joint has been
removed from the car and cleansed of all oil and dirt can you see it.
A
MOT history on
majority of the cars on the road today will be able to confirm that a common
reason for a MOT failure is due to a split CV boot which has resulted in the
grease leaking out and starving the CV joint of lubrication.
If
you're interested how many times your car has failed a MOT test, and one of the
causes is a damaged CV joint, go online and look up your vehicle's MOT
history check. This report will include information on all past MOTs, as
well as the cause for any failures, any MOT warnings, and the car's mileage per
MOT test.
What Are CV Joints and How Do They Work?
Firstly,
we need to clarify what a CV joint is and where it's found, so you'll know
what we are talking about and have a better knowledge of this essential
vehicle component.
On
either end of an axle, there are CV joints. There are inner and outer CV joints
on each axle.
The
inner CV joint is the one that connects the transmission to the body. The inner
CV joint's splines match with the transmission differential's splines to turn
the axle (splines are little teeth that lock together to produce a detachable
combination of parts).
The
outer CV joint is connected to the splines of the wheel hub and is placed on
the outer section of the axle. The outer CV joint normally slides into the
wheel hub splines and is connected to the hub by an axle nut positioned in the
disc or drum's centre.
Damage
to the CV joint cup, where the CV joint bearings ride, is frequently the source
of your vibration. During typical driving circumstances, the damage appears as
pits in the smooth metal surface where the bearings glide up and down.
When
you complete a MOT history check online and are wondering why this is a
common reason for a MOT failure. The simple answer is due to the amount of
stretching of the CV boot every time turning the wheel overtime causes a split
in the CV boot resulting in the grease leaking out. If not repaired in time,
this will result in a total breakdown of your car and will not be able to drive
it.
The
inner cup to bearing mating surface has a very tight clearance, and any minor
deviation in the clearance can cause vibration.
It
is impossible to repair the inner CV joint after it has been damaged in this
way. The CV joint or the complete axle will need to be replaced.
