Nissan Murano: Repairing Procedures and Precautions / Replacement of Panel

Replacement of Panel

Panel replacement work includes replacement of the front fenders and hood which are installed by bolts, and replacement of rear fenders and the roof which are welded. This section explains panel replacement procedures after adjusting body alignment.

(a) Grind the edge of the door panel using 3M Cubitron II Abrasive Fibre Disc #33415 (grade 60+) or equivalent.

(b) Insert the tip of a sharp-edged tool, such as a chisel, into the clearance at door outer panel. Use a hammer to tap the tool inserted into the clearance from the side to separate the door inner panel and door outer panel.

(c) Remove the adhesive adhering to the door inner panel flange area surface.

(d) Adjust the position where the new door outer panel and door inner panel overlap. Once these are positioned correctly, fix them with clamps to prevent them from being displaced.

Apply new adhesive to both door outer panel and door inner panel.

(e) Hold the dolly on the corners of the flange at door outer panel. Tap the dolly with a hammer to bend the door outer panel flange area gradually.

(f) Bend with hammer until the angle of the whole circumference of the door outer panel flange area becomes approximately 45°.

(g) Check that the position of the door outer panel and door inner panel is not displaced while tapping it with a hammer to bend it until the angle of whole circumference of the door outer panel flange area becomes approximately 15°.

(h) Check that the position of the door outer panel and door inner panel is not displaced while taping it with a hammer to bend it until the angle of the whole circumference of the door outer panel flange area becomes approximately 0°.

(i) Use the hemming tool [SST: KV991-10000] to adjust the shape of the whole circumference of the door outer panel flange area.

(j) Seal up the area around the hemmed end of the flange.

Fitting adjustment means adjustment of clearance or gradient of the hood, door, front fender, etc. with respect to its adjacent part, and adjustment of gradient at the press line.

Adjustment of front fender is described as an example.

• Adjust the fitting at the front fender mounting position. Tighten the front fender mounting bolts loosely, and adjust the fit by moving the front fender sideways or in the up-down direction while observing the clearance with the hood and door.

  

• Adjust the front fender bend angle.

  If a proper fit cannot be obtained by step (1) above, change the bending angle of the front fender.

  Explanation	Condition	Correction method
  When the clearance between the front fender and hood is too small: Apply a flat wood plate to the upper corner of front fender, and correct by hammering. Before hammering, securely tighten the front fender mounting bolts.
  When the clearance between the front fender and hood is too large: Apply a scribing chisel to the bend at the base of the front fender. Tap with a hammer to adjust the clearance. Securely tighten the front fender mounting bolts before tapping. Apply the scribing chisel along the press line.

When there is excessive clearance on the upper part of door:

• Apply a wood block between the outer sill and the lower side of door, and push the upper part of door.

  

• When there is excessive clearance on the lower part of door.
