Spicer 1310 Series Greasable Driveshaft & Axle U-Joint Kit (Outside Snap Rings)

Eliminate frustrating driveline vibrations, stop loud metallic clunking when shifting gears, and restore factory-smooth power delivery with this genuine Spicer 1310 Series U-Joint Kit. As the absolute benchmark size for light trucks, classic cars, and off-road vehicles, this premium component is the definitive original equipment solution to service your driveshaft or 4WD front axle shafts.

Universal joints endure constant twisting forces, severe angles, and high rotational speeds. Over time, internal lubrication breaks down from moisture or age, causing the needle bearings to gall, seize, or wear out. A failing U-joint typically alerts you with a high-pitched squeaking at low speeds, a persistent driveline vibration that worsens with acceleration, or a harsh clunk when moving from park to drive. Ignoring these warning signs can result in a catastrophic joint snap, dropping the driveshaft and causing severe undercarriage damage.

Unlike sealed, non-serviceable options, this original equipment manufacturer (OEM) Spicer design is fully greasable. It features an integrated grease zerk fitting in the cross body, allowing you to flush out trail water, road salt, and dirt during routine maintenance. Precision-ground from case-hardened alloy steel, choosing a genuine Spicer replacement ensures strict original equipment tolerances are met for maximum fatigue life.
