TAILGATE CABLE ASSY. RATTLES INSTALL NEW DESIGN CABLE ASSY.

Subject: TAILGATE CABLE ASSEMBLY RATTLES

Model and Year: 1988-91 C/K TRUCKS

Some owners of 1988-1991 C/K vehicles may comment that they experience rattles emanating from the tailgate link arm assembly. The rattle is a result of excessive play between the two halves of the metal link arm and between the link arm and the mating components.

This condition may be corrected by replacing both the left and right hand metal link arms (Figure 1) with rubber cables (P/N 15675385 (LH) and 15675386 (RH) (Figure 2). These rubber cables were designed to fit more securely against the latch to eliminate the excessive play between the two halves of the link arm.

SERVICE PROCEDURE

1. Lower and support the tailgate.

2. Lift the link arm assemblies off the striker bolts.

3. Remove the six bolts (three on each side) attaching the latch assemblies to the tailgate (Figure 1).

4. Remove the striker bolts from the pickup box.

5. Install the latch assemblies with the redesigned rubber cables (P/N 15675385 (LH) and 15675386 (RH).

6. Install the six bolts (three on each side) into the latch assemblies (Figure 2).

7. Tighten the bolts attaching the cables to the tailgate to 25 N.m. (18 lbs. ft.).

Important: DO NOT torque the bolts over 25 N.m. (1 8 lbs. ft.). Exceeding the torque specifications could cause the cable assembly to catch against the latch assembly.

8. Install new striker bolts (P/N 15673252). Torque the striker bolts to 63 N.m (47 lbs. ft.).

9. Raise the tailgate and attach the cables to the striker bolts.
