Transfer power across changing driveline angles with the SKF UJ377 Universal Joint, a greasable Brute Force u-joint built to SKF's quality standards. It fits many vehicles, among them the 1986-1996 Ford F-150, 1997-2012 Jeep Wrangler and 1994-2001 Dodge Ram 1500. See the "Vehicles it fits" section for the full list. Depending on the application, it is cataloged as the rear shaft front joint, as a front axle shaft left outer, right outer or right inner joint, or for the front axle at the wheels.
- Brute Performance bearing cups: the cups are cold-formed and case-hardened using an advanced manufacturing process.
- Thrust washers: designed to eliminate metal-to-metal contact, reduce wear and lower the overall operating temperature.
- Rust protection: a black oxide coating helps the joint hold up in corrosive conditions.
- Greasable design: the joint can be serviced with grease as part of routine driveline maintenance.
SKF states that its universal joints are made from premium materials and meet or surpass original-equipment specifications.
Signs a universal joint may need replacing include a clunk when shifting between drive and reverse, driveline vibration, squeaking at low speed, or noticeable play in the joint. If a worn u-joint is the cause, the UJ377 replaces it. Consult the vehicle service information for the correct installation procedure and any retaining hardware.

What does a universal joint do?
A universal joint links two shafts so they can transmit rotation while operating at an angle to each other. This lets the driveline flex as the suspension moves.
Can the SKF UJ377 be greased?
Yes. SKF lists the UJ377 as greasable. Follow the vehicle service information for lubrication intervals and the recommended grease.
What are signs a u-joint may need replacing?
Common signs include a clunk when shifting into drive or reverse, driveline vibration, squeaking, or play in the joint. Diagnose the cause first, because other driveline parts can produce similar symptoms.
