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