A. Inspect Tubes For Corrosion and Install Retaining Clip

1. With ignition switch in the off position, raise vehicle on a hoist.





2. Remove and discard the under body bracket and rubber isolator retaining the rear brake tubes, fuel vapor tube and fuel supply tube (Figure 1).





3. Carefully inspect all four tubes in the area that was covered by the rubber isolator as shown in figure 2. If any one of the four tubes have any RED CORROSION, the tube(s) must be replaced. Proceed to section B. Replace Corroded Tube(s) and Install Retaining Clip". Tubes with white powder or other residue/discoloration do not require replacement.





4. If no red corrosion is present on any of the four tubes, reinstall the two outboard bolts into the frame rail and crossmember holes and torque to 250 in-lbs (28 N.m) (Figure 3)

Note:
The two outboard bolts must be installed to assure the structural integrity of the frame rail.

5. Snap the provided clip onto the four tubes so that the nipple on bottom of clip is in the outboard position. The clip should be positioned at the forward edge of the center crossmember as shown in figure 3.

6. Using the screw hole in the clip as a template, center punch, then drill a 3/16 inch (4.8 mm) hole in the crossmember for the clip retaining screw (Figure 3).

7. Secure clip to the crossmember and torque the provided retaining screw to 30 in-lbs (3 N.m) (Figure 3).

8. Lower vehicle from hoist.
