🔌 Function

Transfers rotational torque through the driveline while maintaining the specified length, flange alignment and dynamic balance.

⚠️ Common Signs of Failure

• Driveline vibration that increases with speed
• Clunking during load changes
• Worn universal joints or flange movement
• Visible bending, impact damage or missing balance weights
• Fretting, loose flange fasteners or damaged pilot surfaces

🛠️ Service Notes

• Inspect the splines, keyway, taper, threads and seal running surfaces before fitting — corrosion, scoring or damaged splines mean the shaft goes no further
• Renew the seals, O-rings and bearings that run on or seal against the shaft while it is out; the labour to go back in later costs far more than the parts
• Grease splines and mating faces lightly with the lubricant specified for your drive and wipe the excess away — do not pack a taper joint with grease
• Renew the lock nut, tab washer or split pin rather than reusing it, and tighten to the figure and procedure in the workshop manual for your engine or drive
• Check free rotation and alignment by hand after assembly, then check for run-out, vibration and leaks on a short trial run before normal service
