Driving On Bad Ball Joints

What Are The Bad Ball Joint Symptoms And How To Fix It!

In this video I explain why it is unsafe to drive with bad ball joints. I go over three different scenarios of how a ball joint can be bad and how each thre.

We’re sorry.

A car with a bad U-joint will break down in a few hundred miles at the maximum. But if you have a bad U-joint and you are having a transmission fluid leakage, you should not drive your car since the U-joint may break down anytime and will cause damage to the brake line, drive shaft, transmission line and other parts.

You have no choice but have it towed to a mechanic. Typically, the U-joints last the lifespan of a vehicle. But as with any other parts in your car, it can break time any time and may need replacement. When you start noticing that they are not running as it should be, you should have them replaced as soon as possible. The safest thing to do is to seek professional help once you notice any sign of failing U-joints. The U-joint is the short term for Universal joint which refers to a rigid joint or coupling that has axis or rods that are inclined toward each other at a right angle or a degree angle.

U-joints are one of the main parts of the transmission system. The function of the U-joint is to transfer rotational power from the engine onto the wheels of your car. Another purpose of U-joints is to adjust the height misalignment between the rear axle and the power transmission. They are not a typical, velocity-type joint. They are made to give torque and prevent speed fluctuations from happening.

One of their awesome features is that they are dependable and noise-free in operation. What happens if a U-joint breaks while driving? If the U-joint breaks while you are driving, you will lose control over your car and it may tip over.

This can lead to not only irreversible damage but also fatal accidents. As mentioned previously, a broken U-joint can damage the power transmission, brake line and other components of the car and can cause damage to the car or the driver. How do you tell if a U-joint is going bad?

You can tell a U-joint is going bad or failing when you start noticing any of these common symptoms of a failing U-joint: Squeaking noise when you start to move your car forward or reverse — The bearing parts of each U-joint are greased at the factory, but may be without grease fitting to let further lubrication after the car is put into use which limits their service life. Because the bearing part of each U-joint twists a tiny amount with each rotation of the driveshaft but always in the same place the grease can be thrown out of the bearing cup or simply evaporate.

You will not hear the squeaking noise when the car runs faster than five to 10 mph due to other vehicle noise. The squeak is one of the signs that tell you that you should have your U-joint serviced by a mechanic. Doing so can extend the life of your existing U-joints. Clunking with a ringing sound when you shift from Drive to Reverse — Oftentimes, this noise is a sign that the U-joint bearings have enough excess clearance to let the driveshaft rotate slightly, then come to a hard stop, when power is reversed.

This is the next phase of deterioration after having inadequate grease in the u-joint bearings. Unfortunately, when this happens, the damage can no longer be reversed but servicing or greasing the U-joint bearings may extend its life. Vibrations felt throughout the car while running forward at speed — Your U-joint bearings are worn enough to let the driveshaft move outside its normal rotational path resulting in imbalance and causing vibrations.

This is a higher frequency type of vibration compared to that of an out of balance wheel because the driveshaft rotates 3 to 4 times faster than the wheels. The worn U-joint now wreaks havoc to other parts of the car including the transmission. The vibration mentioned previously has now damaged the transmission output shaft seal and worn the transmission tailshaft bushing causing transmission fluid to leak.

Car can no longer move under its own power and the driveshaft is dislocated — When the driveshaft is no longer attached to the rear axle or transmission, it means your U-joint is completely kaput. The drive shaft is dislocated and can no longer transfer power.

Are U joints hard to replace? The replacement of the entire driveshaft is very easy, if not the easiest. When there are compatible U-joints available, it will be worth the effort to replace all of them. You are lucky if you only have to replace your U-joints and not the whole driveshaft. In fact, you can even replace U-joints on your own. You will also need the following: Hammer or a U-joint tool or a Powerbuilt ball joint tool — to knock the car part out of its socket Jack A pair of jack stands Wrenches.
