GM-48894 is required to service the Oetiker low-profile drive axle boot clamps properly. Current service information references tools that cause irreparable damage to the clamps. The double-fulcrum design of GM-48894 facilitates one-handed operation, and the working end of GM-48894 is specifically designed to properly interface with Oetiker low-profile clamps without damaging them. Attempts to service the low-profile drive axle clamps without GM-48894 may result in component damage and/or increased labor time.
