U-Joint
U-Joint With Pressed Bearings CZ201-1
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. They are part of the system that enables the rotating crankshaft in a vehicle's engine to transfer that rotating motion to the rear wheels in a rear-wheel-drive vehicle. Because they provide a flexible connection at the driveshaft's ends, they allow the driveshaft to move up and down and at an angle to the engine as the vehicle encounters uneven road surfaces.

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.
They are part of the system that enables the rotating crankshaft in a vehicle's engine to transfer that rotating motion to the rear wheels in a rear-wheel-drive vehicle. Because they provide a flexible connection at the driveshaft's ends, they allow the driveshaft to move up and down and at an angle to the engine as the vehicle encounters uneven road surfaces.
For example, pickup trucks have universal joints at both ends of their driveshafts. Typically, the u-joints connect to yokes that allow for a driveshaft's fore-and-aft movement and the up-and-down movement for which the universal joints compensate. Without universal joints or some similar system, it would be impossible for a vehicle to have a suspension that offers any substantive wheel travel. The driveline would bind with every bump and pothole.
Front-wheel-drive vehicles have constant velocity joints or CV joints. They perform a similar function to universal joints.

Product Advantages:
1. Large load capacity, the cross shaft mainly bears radial load, but also can bear axial load.
2. Excellent workmanship, each part is made of high-strength metal, stable and durable
3. Quality assurance, the cross shaft uses enough materials to effectively prevent deformation and breakage
How to Replacing A Universal Joint?
After raising your vehicle off the ground with a jack, jack stands, and wheel chocks, you'll need to remove your driveshaft from the vehicle by unbolting it at both ends. Depending on vehicle application, you may encounter one or both of the setups in the above picture. The left picture shows loosening of u-bolts or u-straps nuts.
NOTE! Before removal, mark the relative positions of the shaft and yoke, so that they can be reinstalled in the same "phase".
Using a heavy-duty screwdriver or small pry bar, pry the shaft forward (or rearward) until it's free of the other yoke not attached to the driveshaft, then pull it loose.
Step 2 - Remove The Snap Ring Clips From The Old U-Joint's Bearing Caps
Once you've removed your driveshaft from the vehicle, you'll need to remove the snap ring clips that hold the u-joint's cross piece to the yoke. You'll find specialized c-clip removal tools for inner snap rings (left pic) and needle-nose pliers for outer snap rings (right pic) in the pliers section of our website. Remove the snap rings by squeezing the ends together with the removal tool. If they are overly corroded and don't come free easily, soak the u-joint with some liquid penetrant.
Step 3 - Tap The Old U-Joint Cross Piece Out Of The Yoke Ear
The next step is to tap the old u-joint cross piece out of the yoke ear that it's snugged into. A shop vise is an effective tool for holding the end of the yoke - once you've got it firmly held, use a properly sized punch (or even a socket) and a hammer to tap the joint far enough through so that the cross-piece drops out.
Once you've tapped the joint through the yoke ear, remove the bearing cup in order to fully remove the loose joint section.
Pack the new bearing caps (that came with your kit) with u-joint lubricating grease, then fit them onto the prongs of your new cross piece. Depending on the design of your vehicle's yoke, you may be putting on the bearing cups before or after the new cross piece is inserted into the yoke. Coat all parts that make contact with one another with lubricating grease as well. Install the new clips in the same fashion you removed the old ones. You've now got a new universal joint installed, so go ahead and re-install your driveshaft.
