- Clean the drive shaft splines and bearing surfaces thoroughly, removing any old grease or debris.
- Install the new cross and bearing U-joint into the housing, ensuring proper alignment with the drive shaft. Seat the bearings fully into their respective positions.
- Secure the U-joint with new retaining clips or fasteners as specified by the manufacturer. Verify that all components move freely without binding.
- Lubricate the U-joint assembly and surrounding bearings with marine-grade grease per manufacturer specifications.
- Reinstall the lower unit onto the upper gear housing, aligning mounting holes carefully. Torque all bolts to the specified values in sequence.
- Refill the gear housing with the correct type and quantity of gear lube. Reinstall the propeller and torque the prop nut to specification.

Q: How do I confirm this U-joint fits my Mercruiser sterndrive?
A: Cross-reference your current part number with the list provided (75832T, 75832A3, 75832A2, etc.). Also verify your sterndrive model (Alpha One SS, Alpha One Gen II, or Bravo I/II/III) and serial number range against the compatibility table above.
