SUBJECT: CREAKING OR CRUNCHNG NOISE FROM THE FUEL TANK AREA
MODELS AFFECTED: 1987-1988 ALLANTES
Some 1987-1988 Allantes may experience a condition of a creaking or crunching noise from the rear floor pan while turning. This noise may increase when the body flexes (e.g. turning into a driveway or going over a curb).
This condition may be caused the fuel tank flange contacting the strap mounting bracket and/or the mounting strap at the left (driver side) forward location.
FIGURE 1 - FUEL TANK FLANGE:
To repair this condition use the following procedure:
1. Raise car to expose the fuel tank.
2. Inspect for the fuel tank flange contacting the strap mounting bracket and/or mounting strap at the left forward location, refer to Figure 1.
3. Bend the fuel tank flange downward behind the mounting bracket using channel-lock pliers or equivalent to eliminate the contact. When bending the flange downward, there should still be clearance between the mounting strap and the fuel tank flange, refer to Figure 1.
NOTE: If the fuel tank flange is trapped between the mounting bracket and strap, it may be necessary to remove the strap before trying to bend the fuel tank flange. Support the tank using a floor jack.
