For better torque transmission at different angles and heights

TYPES OF UNIVERSAL JOINTS

• Variable velocity jointI. Cross or spider typeII. Ring typeIII. Ball & turnion type

• Constant velocity jointI. RzeppaII. Bendix weeissIII. Tracta

CONSTRUCTION

A steel ‘X’ with each end precision machined.

Bearings caps with small needle bearings fit over each end.

Grooves for retaining rings are cut into each cap.

A grease fitting is fitted to allow for regular lubriciation.

LOCATION

One universal joint is attached to the driveshaft at each end.

The front u-joint is also attached to a slip yoke which fits into the tailstock of the transmission.

Some heavy duty vehicles with a two-piece shaft have three u-joints

Some older 4 wheel drive vehicles have a u-joint at each front wheel also.

PROBLEMS

Universal joints wear from high mileage and a lack of regular lubrication.

Dry u-joints rust and seize, causing noises and vibration.

Excessively worn u-joints can break, causing costly damage.
