Volvo Penta Complete Universal Joint Assembly – 3862425
Part Information
- Part Number: 3862425
- Brand: Volvo Penta
- Official Product Type: Universal Joint – Complete Assembly
- OEM Status: Genuine Volvo Penta
- System: Sterndrive – U-Joint and Bearing Carrier Assembly
- Related Spider Kit: 3843136 (spider/cross joint repair kit – sold separately)
- Weight: Approx. 2.5 kg (5.5 lb)
What This Part Is
The 3862425 is the genuine Volvo Penta OEM complete universal joint assembly for the DPH-E sterndrive U-joint and bearing-carrier section. It transfers engine torque through the drive while allowing the angular movement required between the engine/transom assembly and the upper gear housing. Volvo Penta’s parts catalog explicitly identifies this as “Universal Joint | Complete” — it is the full yoke and spider assembly, not the spider repair kit alone.
If only the cross/spider section is worn and the yokes remain undamaged, Volvo Penta lists 3843136 as the spider-kit service component. If the complete assembly is worn or damaged, 3862425 is the correct complete replacement unit.

Also associated with earlier DPH-family installations. Confirm by sterndrive model and serial number against the Volvo Penta U-joint and bearing-carrier assembly diagram before ordering.
Serial Number Fitment Notice
Match by sterndrive model and parts diagram, not engine displacement alone. Use your DPH drive serial number to confirm that 3862425 is specified in the U-joint and bearing-carrier section for your specific drive configuration before ordering.
Complete Assembly vs. Spider Kit
Volvo Penta offers two service options for this joint:
- 3862425 – Complete universal joint assembly (yokes, spider, and bearings). Use when the complete assembly is damaged, heavily worn, or when a full assembly replacement is preferred.
- 3843136 – Spider/cross joint repair kit only. Use when the yoke assembly is serviceable and only the cross and bearing cups need replacement.
Confirm which repair scope is appropriate for your drive before ordering.
When to Replace
- Play or looseness detected in the U-joint under load or inspection
- Knocking or vibration develops under acceleration or load
- Joint movement feels rough, notchy, or binds at any angle
- Corrosion present around the cross bearings or yoke journals
- Water intrusion from a failed bellows has reached the U-joint area
- Complete assembly is damaged during upper-drive or bearing-carrier service
Installation Notes
Inspect the U-joint bellows, sealing ring 3863084, roller bearings, bearing box, shims, and all adjacent hardware whenever the assembly is removed. These components are listed together in the DPH-E U-joint and bearing-carrier section and should all be assessed while the area is accessible. A compromised U-joint can cause vibration and accelerated wear in the upper gear housing and bearing-carrier assembly if not properly corrected.
Technical FAQ
Q: What is the difference between 3862425 and 3843136?
A: 3862425 is the complete universal joint assembly — the full yoke, spider, and bearing unit. 3843136 is the spider repair kit only. If the yokes are in good condition, 3843136 may be sufficient. If the complete assembly is damaged or heavily worn, 3862425 is the correct replacement.
Q: Does this fit earlier DPH drives besides DPH-E?
A: The primary confirmed fitment is DPH-E with D4/D6 engines. For earlier DPH variants, confirm against your specific drive serial number and parts diagram. See also the Volvo Penta Complete Universal Joint 3887297 for DPH/DPR/DPI if your drive is an earlier generation.
Q: Should the U-joint bellows be replaced at the same time?
A: Yes, if the bellows has not been recently replaced or shows any cracking, hardening, or deterioration. Water intrusion through a failed bellows is one of the primary causes of U-joint failure on DPH drives.

Parts Desk Insights
At $2,136, this is one of the higher-cost DPH drivetrain components — so confirming whether the complete assembly or just the spider kit (3843136) is needed before ordering is worth the extra step. The most common scenario is a bellows failure that went undetected long enough for water to reach the U-joint area, causing bearing corrosion that makes a complete assembly replacement necessary rather than a spider-kit repair. If you’re replacing the U-joint, inspect the bellows, sealing ring 3863084, and bearing-carrier components at the same time — doing it all in one opening is significantly less expensive than coming back for a second drive-out service.
