Description
Direct replacement u-joint. 938″ cap, 1.500″ width. ISR retention, Greasable. SPICER. Lube fitting in body.
That knock you hear pulling out of a driveway isn't the suspension — it's usually the u-joint. The Spicer - 5-103X Universal Joint is the direct fix.
The 1000 series runs a varies cap diameter across a varies width — built for multi-application use. It's the standard cross on fits multiple series/platforms — verify dimensions.
Retention is Inside Snap Ring (ISR) — Circlips seat inside the yoke bore. Common on import vehicles, front axle yokes, and some OEM assemblies. Requires internal snap ring pliers. Greasable with standard chassis grease — service every 30,000–50,000 miles for best longevity. Use a quality CV/chassis grease, not wheel bearing grease.
Dimensions: 938" cap, 1.500" width. Note: Lube fitting in body. Verify your yoke dimensions before ordering — a mis-matched cap diameter won't seat correctly and will fail early.
