Front Left Suspension Assembly - 2002 Corvette C5 LS1

When sourcing front left suspension components for your 2002 Chevrolet Corvette C5, focus on the steering knuckle assembly (GM 10218921) and control arms (GM 10258833 lower, GM 10258834 upper). These components interchange across 1997-2004 base model Coupes and Convertibles equipped with the LS1, but strictly avoid Z06 variants which utilize unique knuckles featuring thicker steering arms to accommodate larger brake calipers. At the junkyard, inspect the aluminum knuckle for stress cracks around the steering arm ball joint tower and caliper mounting ears—common failure points after curb impacts. Check control arm ball joint boots for grease contamination tears and verify wheel bearing smoothness (GM 12413037) by rotating the hub while feeling for notchiness. Installation requires precise torque specifications due to aluminum construction; over-tightening risks thread stripping. Always use new cotter pins and torque the axle nut to 118 lb-ft. Post-installation alignment is mandatory as the SLA suspension geometry is sensitive to camber changes.
