That's the thing. Only part number I have around is 9181408 - not sure it'll fit your application, but it might point you in the right direction. Splines on both this coupler/sleeve and the shaft on the BG should have the profile of a triangle - not the Eifel Tower.
Never rebuilt one. Thanks for the parts numbers, though. Handy. Like I say, never had bearing troubles, always stripped splines on horizontal shaft which engages above coupler/sleeve.
More common on heavier second gen XC70 and most common on XC90. Don't think horsepower plays too much of a factor. More dependent on vehicle weight and driving habits.
