5-2117X UDS 2C 4LWD (994) Universal Joint

5-2117X UDS 2C Series 4LWD Universal Joint — 1.312" Cap Diameter, 3.125" Width, Greaseable

The 5-2117X is a UDS 2C series universal joint in the 4LWD style, with a 1.312-inch cap diameter and an overall width of 3.125 inches. The "X" suffix designates a greaseable design with a zerk fitting in the cross body, allowing field lubrication of the four trunnion needle bearing assemblies. The 4LWD style designation indicates a configuration specific to four-wheel-drive light-truck front driveshaft applications, where higher operating angles and frequent torque reversals place elevated demands on trunnion bearing lubrication. Cross-references for the 5-2117X include Precision 454, 2C-LWD, and 2060-X.

The 2C series with a 1.312-inch cap diameter sits between the common light-truck series in Spicer's numbering system; while the 2C designation is a Mechanics/industrial series rather than a standard 1310/1350 automotive series, the 1.312-inch cap diameter and 3.125-inch overall width define the machined bore dimensions required in both mating yoke ears. Any yoke used with the 5-2117X must have a bore machined to accept a 1.312-inch cap — this is not the same as a 1310 series cap (1.062-inch) or a 1350 series cap (1.188-inch), and those yokes cannot be used with this joint. The overall width of 3.125 inches is the center-to-center span across both caps in the primary plane; verify this dimension fits within the yoke ear spread on both the driving and driven yokes without binding. The Type 13 designation in the product attributes refers to the retention style — confirm the mating yokes use the correct snap ring or retention hardware compatible with this type. The greaseable design requires lubrication at installation and at regular service intervals per the OEM schedule; sealed variants of this cross-size exist but are not interchangeable with greaseable yoke configurations that rely on the zerk port location for clearance.

Fitment & Installation Notes

Before installing the 5-2117X, measure the cap bore diameter in both mating yoke ears and confirm it is machined for a 1.312-inch cap. Do not use a 1310 yoke (1.062-inch bore) or a 1350 yoke (1.188-inch bore) with this U-joint — the cap diameter is different from both standard automotive series and the caps will not be retained correctly. Verify the 3.125-inch overall width fits the yoke ear spread with the snap rings seated; the caps must snap in fully without axial preload or binding. Check the Type 13 retention hardware specification against your yokes before assembly, as retention style affects how the caps are secured in the bores.

The 4LWD style indicates this joint is configured for a front driveshaft application on a four-wheel-drive light truck or SUV. Front driveshafts operate at higher steady-state U-joint angles than rear driveshafts on the same vehicle, particularly on lifted applications where the increased ride height steepens the front driveshaft angle to the transfer case output. At elevated operating angles, needle bearing lubrication becomes the primary factor governing service life; grease the 5-2117X at the zerk fitting during installation. The cross-references Precision 454 and 2060-X confirm aftermarket availability under alternate part numbers, but verify cap diameter and width against those numbers before substituting — cross-reference databases occasionally group physically similar but non-identical joints. Use the 5-2117X only with yokes confirmed to accept a 1.312-inch cap in the Type 13 retention configuration.
