What does the U in Ujoint mean?
universal joint
A universal joint (also called a universal coupling or U-joint) is a joint or coupling connecting rigid shafts whose axes are inclined to each other. It is commonly used in shafts that transmit rotary motion.
What is a double D steering shaft?
JEGS Double ”D” Steering Shafts
JEGS Double “D” Steering shafts are easy to assemble and can be cut to length where needed. Double “D” steering shafts are preferred over welding to the u-joints since there is less risk of damage to the roller bearings from the welding heat.
What does a Ujoint do?
A u-joint, or universal joint, is a component that connects the driveshaft to the differential, and sometimes connects the driveshaft to the transmission or two driveshafts to each other. It’s a cross shaped piece with a bearing at each end, that allows for lateral and side to side movement of the driveshaft.
What is a Ujoint on a car?
Universal joints are X-shaped parts typically made of steel with a bearing cap at each end that allows the vehicle’s rigid driveshaft to connect to the transmission and rotate freely.

How are Double D steering shafts measured?
If it is a DD shaft (two rounds and two flats), then measure the rounds – it will either be a 1″ DD or 3/4″ DD. If there are splines, then measure the diameter of the shaft and count the individual splines.
How do I know if my U-joints are going bad?
How to Diagnose and Replace Universal Joints (ULTIMATE Guide)
Are U-joints hard to replace?
Replacing a U-Joint is not a difficult job. But it does take patience, care, and attention to detail. That’s especially the case when working on vehicles with components that must be removed for full access to the driveshaft.
How often should you replace U-joints?
about 100K miles
U-joints don’t last forever. They usually last about 100K miles. Like all car parts, U-joints develop wear and tear over time.
How hard is it to replace U-joints?
Replacing these joints is a fairly straightforward job, though it takes some prior experience. To begin, you’ll need a universal joint pressing tool. You can also take advantage of the loaner tools program at your local Advance Auto Parts store. Then follow these step-by-step instructions on how to change U joints.
What are the different types of U-joints?
There are two types of U-joints, the cross and roller type and the ball and trunnion type. The cross and roller type is used the most; it allows the drive shaft to bend. The ball and trunnion type less frequently used; it allows the drive shaft to bend and also permits backward and forward motion of the drive shaft.
How strong is a 1350 U-joint?
Relying on information provided by the manufacturer of the components, our calculation is that the 1350 series joint is about 37.5-percent stronger than the 1310 series. The 1350 U-joint is rated for 2,200 lb-ft (minimum elastic limit) of torque.
Are both U joints the same size?
This allows you to mate a larger (or smaller) U-joint to the other. For example, you buy a new driveshaft that comes with 1350 weld-in yokes, but your car has 1310-sized yokes for the transmission and rear differential.

How do I know what slip yoke I need?
Measure OE slip yoke with a precision tool to determine which yoke you need. length, journal size & U-joint series are critical dimensions requiring accurate measurement. Some slip yokes have missing splines – include the missing spline in your count or count the splines on the transmission output shaft to be accurate.

How many U-joints can a steering shaft have?
There’s no limit on how many universal joints can be used in a steering system, but three is common with today’s engine/chassis layout.
Can you still drive with a bad u-joint?
A U-joint, or universal joint, is the part of the drive-shaft that transfers power from the transmission to the differential. If it malfunctions or fails, your vehicle will not be able to drive.
What happens if u-joint breaks while driving?
Vehicle Cannot Move
When the universal joint breaks down, the driveshaft will drop, no longer able to transfer power. At that point, you may not be able to get away with just a U-joint replacement; the entire driveshaft might need to be changed.
How long should U-joints last?
U-joints don’t last forever. They usually last about 100K miles. Like all car parts, U-joints develop wear and tear over time. When your U-joints fail, it’s very important to replace them as soon as possible.
How much does it cost to replace u-joints?
The u-joint replacement cost is estimated between $225 and $300. Labor makes up about $100 to $125, while the parts should be between $125 and $200. However, these prices vary based on what make and model vehicle you drive.
How do you tell what u-joint I have?
You will need to measure from the edge of one snap ring groove straight across to the edge of the other snap ring groove. For U-joints with outside snap rings, you will need to measure from the edge of one u-joint cap straight across to the edge of the other u-joint cap.
