Modifying the Drift
WARNING: This page is about a different car, the 2002 Volvo C70, 2001 Volvo C70, 2000 Volvo C70, 1999 Volvo C70, and 1998 Volvo C70. However, it is still accessible from the selected car via links, so may be relevant.
Grind a drift as illustrated. This is to facilitate removing the constant velocity joints
The rounding at the lower edge (R) means that the drift will not catch in the circlip groove on the drive shaft. The slightly sharper angle (approximately 60°) means that the drift has a greater mating surface against the inner ring.
