A.Non-Sleeved Lower Control Arm Ball Joint

FIGURE 1 - DATE CODES:

1. Inspect both rear lower control arm ball joint date codes. Each ball joint is stamped with four-digit date code, located on the lower ball joint cover near the grease fitting. The date code describes the month, day and year the ball joint was manufactured, and maybe interpreted as shown in Figure 1.
2. Ball joints with date codes 6204 (June 20, 1984) and later were produced with a nylon sleeve for noise reduction. Ball joints with date codes earlier than 6204 should be replaced with service ball joint kit, GMWDD P/N 9769581. Except for date code information, there is no visible difference between sleeved and non-sleeved ball joints.
