Correct Series Identification
Before ordering, confirm your driveshaft uses SERIES 1 series u-joints. Measure across the cap OD of the old joint -- SERIES 1 series measures 0.866". Also check the snap-ring retention style: external snap rings seat in a groove in the yoke ear, while internal snap rings seat in a groove in the cap itself. This cross uses the standard SERIES 1 retention design.
Maintenance Protocol
This is a greaseable cross -- service it at every oil change (or every 5,000 miles, whichever is sooner) with NLGI 2 EP grease via the zerk fitting. Over-greasing is rarely harmful; under-greasing is a leading cause of u-joint failure.
Driveline Angle Check
While the driveshaft is out, check the pinion angle and transmission output angle. Both should be within 1 degree of each other (canceling phasing) and neither should exceed 3 degrees for smooth operation. Adjust pinion angle with shims or adjustable control arms as needed before installing the new joint.
