What Is a U Joint?

The U Joint is an integral part of the drive shaft and transmission and is the ultimate in durability. Its components are precision ground to eliminate premature wear, and special internal valves keep the working surfaces lubricated. U Joints can be installed at a fraction of the cost of a new transmission or drive shaft. However, some factors can accelerate wear and premature failure.


A U-joint is a critical part of your vehicle’s drivetrain. It transfers power from the transmission to the axle housing assembly. It connects to other components of the drivetrain with universal joints, which allow the driveshaft to change angle while the vehicle is moving. It’s important to have a high-quality universal joint, as any defect can cause significant damage to your vehicle and potentially harm you and other vehicle occupants.
There are two types of U-joint: those that bolt into one yoke, and those that are pressed into another. Press-in sides are often secured with C-clips, while bolt-on side types use a locking mechanism. Regardless of which type of U-joint you purchase, it’s important to measure the yoke’s outside and inside locks to ensure the proper fit.
The basic concept of a universal joint dates back to antiquity. The Ancient Greeks used the device on ballistae. In 1545, Gerolamo Cardano suggested using the joint but did not produce a working model of it. In Europe, the device was referred to as a Cardan joint. Eventually, Robert Hooke produced the first working universal joint in 1676.
U-joints are often overlooked, but a failure of this part can be dangerous. Not only can your vehicle not move, but it can also damage other components of the car, causing a breakdown and costly repairs. You should consider getting your vehicle checked for u-joints at regular maintenance intervals.
The cost of replacing a U-joint depends on the parts you purchase and how many joints you need to replace. It is important to remember that this repair is complicated, and it’s best to get a professional. A professional can perform the job correctly and save you hundreds of dollars in the long run.

Types of u-joints

There are different types of u joints, each with its own purpose. Understanding these differences will help you choose the right type. Besides their purpose, u-joints are also divided into sizes. The right size for your vehicle will depend on the type of driveline and your intended use.
The most common type of u-joint is the CZPT 1310 series, which is available at most auto parts stores. It has an external snap ring to hold it in place. A similar type, the CZPT 1330 series, has a larger body and same-size trunnions and caps. It has a high strength rating and is suited for off-road vehicles.
After you have identified the type of u-joint, the next step in repairing it is to replace the bearings. U-joints may have a zerk fitting that allows you to lubricate them. It is important to remove the existing joint temporarily so you don’t create pressure when replacing the new one. When replacing the bearings, make sure to grease them well so that they are secure. Do not over-lubricate the U-joint, as this can result in hydraulic lock.
The CZPT Time-Tempered universal joint kit has a high-quality journal cross that is forged and heat-treated. It also has a grease fitting and through-drilled grease channels. Its journal cross trunnions and faces are grooved for consistent lubrication.
A greasable u-joint is a type of u-joint that is lubricated and has a zerk fitting. You can lubricate this type of u-joint by using a grease gun and applying a new layer of grease. This will increase its lifespan by up to 50%.

Functions of a u-joint

A u-joint is an important component of your car’s suspension system. Without these joints, your car would not be able to move properly on uneven terrain. They work by allowing your driveshaft to move up and down along with the suspension, so you can drive safely and confidently. If you’re not familiar with these joints, they’re not difficult to find in a vehicle.
Universal joints have two main types: single universal joints, and double universal joints. A single universal joint has one bending joint and operates at a 45-degree angle. A double universal joint, on the other hand, has two bending joints and can function at angles of up to 90 degrees.
Depending on your vehicle’s model, U-joints may need replacing every two to three years. A broken U-joint can cause serious issues for your driveshaft. If the U-joint breaks, your car will be unable to shift gears or transfer power. You may need to replace your entire driveshaft if this happens.
To replace a u-joint, you should first remove the old one. Then, install the new one. Make sure to install the new one at an angle, ideally 90 degrees from the old one. Then, install the snap ring or the C-slip on the opposite side of the yoke. Once the new one is installed, you should tap it to make sure that it’s secured well.
A faulty u-joint can cause thousands of dollars in repairs. In addition, it can cause severe problems if it fails during driving, which may put you at risk for an accident. It is also important to remember that a bad universal joint can cause your driveshaft to fall off and cause a lot of damage.

Cost of a u-joint

The cost of a u-joint replacement will depend on several factors. The most important is the mechanic’s rate. This is because a U-joint replacement will require at least one or two hours of labor, and a $25 part can cost much more if someone else is doing it. A mechanic’s rate is typically between $90 and $200 per hour. However, if you choose a cheaper place, the labor charge could be as low as $15 an hour.
A common reason for higher u-joint replacement costs is a torque converter leak. The leak could be due to a cracked fluid line or torque pump. The repair will cost about $150 to $200, depending on the type of leak. Some parts that are commonly required to replace a u-joint include the pan bolts, drain plugs, gaskets, seals, and flud lines. If you can replace these parts yourself, you can cut your cost by at least $100.
The cost of a u-joint will also depend on whether it is in the front or rear of the vehicle. A rear universal joint replacement will be more expensive than a front one. This is because the front part of the car has more moving parts than the rear part. In addition to this, a u-joint can also break and cause a car to not be drivable. This could mean that a driver needs to get a new driveshaft to drive the vehicle.
If your u-joint is failing, you should have it replaced immediately. Failure of this joint is not a pleasant situation for anyone. In fact, it’s extremely dangerous, especially if you’re driving, because it could cause an accident.

Maintenance of a u-joint

Proper lubrication of a u-joint is an essential part of maintaining your vehicle’s driveline. Many u-joints are sealed, but some are greasable and need to be lubricated periodically. Understanding the type of u-joint you’re using will help you determine when it needs to be serviced and when it’s time to replace it.
A u-joint may be in need of replacement if the bearings are worn out. When this happens, the driveshaft may become unbalanced, causing vibration during acceleration and deceleration. If you notice these symptoms, you should contact a mechanic. To ensure the long-term life of your u-joint bearings, you should purchase a quality replacement.
One of the most common causes of u-joint failure is improper lubrication. If you’ve followed the manufacturer’s recommendations for lubrication, you’ll prevent these problems from affecting the operation of your vehicle. Also, proper lubrication flushes will remove contaminants that may have built up inside the bearing caps.
Proper maintenance of a u-joint is critical for the safety and performance of your fleet. By replacing it when it shows signs of problems, you’ll be saving yourself the hassle of costly repair bills and downtime. A local mechanic can perform the work for you and ensure that your vehicle is in safe condition.
Proper lubrication is essential for your u-joint to run smoothly and without slop or backlash. Regularly cleaning and greasing your U-joint can save you a lot of time and money. You should check your bearing lubrication every week to ensure the proper performance of your drivetrain.
