U-Joint

U-Joint With 4 Plain Round Bearings 5-160X

The universal joint consists of a spider(cross) and four grease-filled roller bearings. It can transmit large torque at low friction. Spider with journal pegs and bearing cases as outer rings were hot forged or cold formed and machined. They are later carburized in the furnace to obtain increased ruggedness and wear resistance.

What Does a Universal Joint Do?

Because vehicles don't travel on surfaces as flat as a billiard table, driveshafts must be able to move up and down with the suspension while continuing to rotate to ensure uninterrupted power flow to the drive wheels. The universal joints enable this movement while allowing the driveshaft to continue to turn.

The use of U-joints makes up for the height misalignment between the transmission and the rear axle that drives the rear wheels. Since a vehicle's rear axle and rear wheels move independently of the rest of the vehicle, a direct driveshaft from the engine to the axle would bind or flex as the vehicle encounters bumps. The u-joints compensate for that motion, keeping the driveshaft spinning freely. As the driveshaft rotates, the flexible "universal" action of the u-joints automatically compensates for misalignment.

What Maintenance Is Necessary?

It's obvious that the vehicle's universal joints get a serious workout any time the car is moving. The faster the vehicle goes and the more its rear axle travels up and down, the greater that workout becomes. This suggests that u-joints require maintenance.

The bearings of each u-joint are greased at the factory during assembly. Some are "lubed for life," and they cannot be serviced with additional lubrication. Other universal joints have grease fittings that allow the addition of grease at service intervals.

In either type, the lubrication can diminish over time, and the "dry" bearing results in wear-causing metal-to-metal contact. You can lubricate universal joints with a grease fitting, but u-joints without that ability will simply wear out and need replacement. Happily, their service life is quite lengthy.

How to Replacing A Universal Joint?

Step 1 - Remove Your Driveshaft

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.

Step 4 - Remove Old Bearing Caps From The Cross Piece Ends

Once you've tapped the joint through the yoke ear, remove the bearing cup in order to fully remove the loose joint section.

Step 5 - Install Your New U-Joint Piece

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.
