A spider is a central hub component in a universal joint that connects drive shafts in vehicle suspension systems.
The spider, also known as a cross or trunnion, is the central component of a universal joint (U-joint) in automotive suspension and drivetrain systems. It consists of a four-armed cross-shaped forging with precision-ground bearing journals at each end. These journals accommodate needle roller bearings and bearing caps that connect to the yokes of the drive shafts. The spider enables torque transmission between shafts operating at variable angles while accommodating suspension movement and misalignment.

The spider is the central cross-shaped component of a universal joint, while the complete U-joint assembly includes the spider, bearing caps, needle bearings, seals, and sometimes the yokes.
Industrial vehicle spiders should be inspected every 50,000 km or 6 months for wear, lubrication condition, and play. Heavy-duty applications may require more frequent inspection based on operating conditions.
While some heavy-duty applications allow rebuilding with new bearings and seals, most automotive applications use sealed units that require complete replacement when worn.
