Installation Notes and Tips

Verify bearing cap diameter, cap-to-cap length, snap ring style, and axle position before installation. This SPL70-4X uses internal snap rings and greaseable construction, so the axle shaft and yoke should be inspected for wear, scoring, or distortion before pressing in the new joint. Confirm the vehicle is a Ford F-250 Super Duty or Ford F-350 Super Duty in the listed year range and that the front axle at wheels application matches the original joint dimensions.

Spicer Life Series components are built around higher bearing capacity and longer service life expectations for driveline use. The SPL70-4X follows Spicer OEM-series sizing and serviceable design standards for front axle universal joint replacement.
