The cross body is heat-treated alloy steel; needle roller bearings are retained in hardened steel caps sealed with elastomer trunnion seals. Lubrication design: sealed (pre-lubricated, no grease fitting).Specification DataItemSpecPart NumberUJ2775UU-Joint SeriesSTAKEDCap Diameter1.062″Overall Width2.952″StyleSTAKEDLubricationsealed (pre-lubricated, no grease fitting)ManufacturerUDSApplication NoteStaked or crimped universal joints do not have snap ringsNeedle Bearing ConstructionEach of the four caps houses a set of needle roller bearings running on a hardened trunnion surface. The trunnion hardness depth must exceed the needle contact zone to prevent brinelling under shock loads. These crosses are manufactured to SAE standards for the STAKED series — cap bore and trunnion dimensions are interchangeable with all OEM and aftermarket STAKED yokes.Application: Staked Series DriveshaftThe STAKED series is the correct specification for STAKED series driveshaft driveshafts. If you are unsure of your series, compare the cap OD on your old cross to the 1.062″ dimension — or measure your yoke cap bore ID directly. Series must match at both the yoke bore and the cross cap.Operating AngleU-joint crosses should operate at angles between 1 and 3 degrees for smooth power transfer and maximum life. Angles above 5 degrees cause cyclic velocity variation (second-order vibration) and accelerate needle bearing fatigue. If your driveshaft angle exceeds 5 degrees, consider a double-cardan (CV) joint arrangement instead.Staked or crimped universal joints do not have snap ringsNew to U-joints?

The UJ2788U is a STAKED series cross with a 1.062″ cap diameter and 3.464″ overall width, designed for STAKED series driveshaft driveshafts. Lubrication: sealed (pre-lubricated, no grease fitting).Cross DimensionsDimensionValueSKUUJ2788USeriesSTAKEDCap Dia.1.062″Width3.464″StyleSTAKEDLubesealed (pre-lubricated, no grease fitting)BrandUDSNotesMOSTLY USED ON SPRINTERHow to Identify Your Correct SeriesMeasure across the cap OD on your old cross — STAKED series measures 1.062″. Also measure overall width (3.464″) and confirm the snap-ring groove style matches. If your yoke has a different cap bore diameter, you need a different series cross — do not force a mis-sized cross into the yoke bore.Replacement Procedure SummarySupport the driveshaft — do not let the shaft hang by the u-joint during removal.Remove snap rings from all four cap pockets.Use a u-joint press or C-clamp to drive each cap out by pressing the opposite cap through.Clean the yoke bores and check for wear or out-of-roundness.Press in the new UJ2788U cross, seating caps squarely and re-installing snap rings.When to ReplaceReplace the cross when you detect: clunking on acceleration or deceleration, vibration at specific speeds, visible rust or grease leakage at the caps, or any detectable play when rocking the driveshaft. A failed u-joint can cause complete driveshaft separation — do not defer replacement.Note: MOSTLY USED ON SPRINTERNew to U-joints?

Confirm all four yoke ear bores are 1310WJ series before ordering — mixing series causes uneven bearing loads and early failure. If you are unsure of your series, measure the cap OD on the old cross or the yoke bore ID.Application: DANA 30 – DANA 35 , DANA 44 FRONT AXLE SHAFT BETWEEN FORD MPAR AND GMThis cross is designed for use in DANA 30 – DANA 35 , DANA 44 FRONT AXLE SHAFT BETWEEN FORD MPAR AND GM applications. Verify both the series and the overall width (2.188″) match your shaft configuration. The width determines the phasing position within the yoke ears — a cross that is too narrow will have excess endplay; one that is too wide will bind.Lubrication & Service LifeThis cross is greaseable. Grease via the zerk fitting at every oil change interval using NLGI 2 extreme-pressure grease — purge until fresh grease exits each seal. Regular greasing is the single most effective way to extend u-joint life.Replacement ProcedureSupport the driveshaft fully — do not let it hang by the joint during removal.Remove all four snap rings from the yoke ear cap pockets.Press each cap out by pushing the opposite cap through the bore.Clean and inspect all four cap bores for wear or out-of-round condition.Press the new 5-297XU caps squarely into the bores and reinstall snap rings.Verify no binding through the full operating angle range.DANA 30 – DANA 35 , DANA 44 FRONT AXLE SHAFT BETWEEN FORD MPAR AND GMNew to U-joints?

This cross is greaseable (zerk fitting included).Technical DataSpecificationValuePart NumberGUA3SeriesSERIES 1Cap Dia.0.866″Width2.126″StyleOSRGreaseableYesBrandUDSNotesBONDIOLI & PAVESICorrect Series IdentificationBefore 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 ProtocolThis 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 CheckWhile 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.App note: BONDIOLI & PAVESINew to U-joints?

This cross is sealed (pre-lubricated, no grease fitting).Technical DataSpecificationValuePart Number9951-71SeriesCap Dia.1.102″Width2.787″StyleOSRGreaseableNoBrandUDSNotesAmphicar Axle JointsCorrect Series IdentificationBefore ordering, confirm your driveshaft uses series u-joints. Measure across the cap OD of the old joint — series measures 1.102″. 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 retention design.Maintenance ProtocolThis is a sealed cross — no periodic greasing is required. Inspect for play, roughness, and seal damage at every major service interval and replace proactively if wear is detected.Driveline Angle CheckWhile 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.App note: Amphicar Axle JointsNew to U-joints?

The cross body is heat-treated alloy steel; needle roller bearings are retained in hardened steel caps sealed with elastomer trunnion seals. Lubrication design: greaseable (zerk fitting included).Specification DataItemSpecPart NumberGUA8U-Joint SeriesAW21Cap Diameter1.062″Overall Width2.937″StyleOSRLubricationgreaseable (zerk fitting included)ManufacturerUDSApplication NotePTO AppNeedle Bearing ConstructionEach of the four caps houses a set of needle roller bearings running on a hardened trunnion surface. The trunnion hardness depth must exceed the needle contact zone to prevent brinelling under shock loads. These crosses are manufactured to SAE standards for the AW21 series — cap bore and trunnion dimensions are interchangeable with all OEM and aftermarket AW21 yokes.Application: Weasler Aw21 / Ab4 Series Power Take-Off (Pto)The AW21 series is the correct specification for Weasler AW21 / AB4 series power take-off (PTO) driveshafts. If you are unsure of your series, compare the cap OD on your old cross to the 1.062″ dimension — or measure your yoke cap bore ID directly. Series must match at both the yoke bore and the cross cap.Operating AngleU-joint crosses should operate at angles between 1 and 3 degrees for smooth power transfer and maximum life. Angles above 5 degrees cause cyclic velocity variation (second-order vibration) and accelerate needle bearing fatigue. If your driveshaft angle exceeds 5 degrees, consider a double-cardan (CV) joint arrangement instead.PTO AppNew to U-joints?

The 3.217" (81.7MM) width is much wider than any 1310 automotive joint, confirming this is a PTO-specific geometry. Do not assume a 1310 automotive U-joint can substitute in this PTO application — the width mismatch will prevent proper snap ring seating in the yoke ears. Grease every 8 operating hours in light agricultural use or every 4 hours in continuous heavy-duty operation. The OSR style allows bearing cup replacement in the field without removing the shaft from the implement.New to U-joints? See our universal joint guide for styles, snap-ring types, and measuring tips.

At this size, the joint is commonly found on 150+ HP tractor PTO shafts and combines where the driveline must sustain high-cycle torque reversals during field operation.The greaseable OSR design is standard for this application class — field maintenance is non-negotiable. A dry PTO U-joint at 45MM cap size running at 540 or 1000 RPM will develop surface fatigue in the needle bearing tracks within hours of dry operation. Follow the implement manufacturer’s lubrication schedule; in continuous high-duty-cycle applications, grease every 4 hours. Keep a spare set of bearing cups and snap rings on the tractor for immediate field repair if a cup spalls.New to U-joints?
