FRONT FLOOR PAN NOISE DURING ACCELERATION AND BRAKING

ALL CHEVROLET DEALERS
A "squeak, crunch, or popping" noise coming from the front floor pan area in some Celebrities and Citations during acceleration and braking may be
experienced. The condition is usually a single pop.
Perform one or a combination of the following steps:
1.
Check cradle alignment to body, adjust if necessary. (Page 3-1 Fisher Body Service Manual).
2.
The cradle mount bolt through the body to the cage nut may make contact with body. This can be corrected by making the cage nut hole larger (see
illustration - Point A).
3.
Clear wax and rubber flash from body mount and cradle mating surfaces. The metal spacer for the mount may be contacting the cradle frame. This
can be corrected by grinding or filing away sufficient material from the spacer to provide clearance, or crushing the spacer in a vise (see
illustration - Point B).
4.
The metal washer which is part of the lower insulator, may be rubbing against the underside edge of the cradle at the point illustrated, outer or side
opposite which is shown in illustration. This may be corrected by grinding or filing off sufficient material from the insulator washer or crush the
neck of the lower body mount slightly in a vise between the flats. This will elongate the mount slightly in the other direction (see illustration -
Point C).
5.
Flatten the lower retainer plate slightly in a vise. This will increase the amount of clamping load on the frame (see illustration).
