Freeing the constant velocity joint
WARNING: This page is about a different car, the 2004 Volvo S40, 2003 Volvo S40, 2002 Volvo S40, 2001 Volvo S40, and 2000 Volvo S40. However, it is still accessible from the selected car via links, so may be relevant.
Secure the drive shaft in a vice. The notch for the snap ring must be upward. Hold the snap ring open. Place the altered drift between the snap ring. Tap out the inner ring on the constant velocity joint slightly on the shaft so that the snap ring remains in the open position.
