We do an EPIC and fully detailed disassembly repair and rebuild of the upper control arm with new genuine GM bushings and ball joints as well as replacing the forged lower control arm ball joints. This video is specific to GM old body style (OBS) 8-lug 4WD K trucks (Suburban Cheyenne Silverado Sierra) such as the K2500 and K3500 or the K1500 with 6.5L diesel engine option. GM part numbers and factory service manual torque values are provided along with special tools and techniques required.
The video shows the procedure performed on the drivers side of a 1998 Chevrolet Cheyenne K2500. Most 4x4 8 lug vehicles across the years covered should be very similar if still using the original GM factory suspension on OBS 1992 1993 1994 1995 1996 1997 1998 1999 2000 Chevrolet GMC and Holden vehicles like the Silverado Sierra Blazer Cheyenne and Suburban.

- Removal and reinstallation of the front disc brake caliper assembly
- Removal and reinstallation of the steering knuckle spindle rotor hub speed sensor assembly
