My GX470 started to rattle like a POS. I believe it's a combination of the holes enlarging over time combined with potholes, that cause the shield to drop. The shield drops on top of the muffler and makes a horrible noise. The Insulator or shield sits above the center muffler between the muffler and the rear seat passenger floor boards. I believe it's there to prevent the rear seat floor from getting hot. This is pretty easy. It takes a little time for the penetrating oil to work and only costs approximately $5.

What you need / what I recommend:

• 4 - Stainless or Zink Fender Washers
• WD-40 or Penetrating Oil
• 10MM Box Wrench
• Vehicle Ramps & Wheel Chocks

What to do:

1. Carefully Drive vehicle up ramps
2. Set emergency brake
3. Chock front wheels
4. Remove front rubber exhaust hanger. Pull the top of the rubber hanger off and rotate the hanger down. This provides clearance to remove the heat insulator and access to nuts.
   
   
   
5. * Optional: If u have any nuts still holding the shield - Apply Penetrating oil to any existing nuts that are still holding the heat shield and wait awhile.
6. After removing any last bolts that are holding the shield, remove the shield by sliding it through the side of the muffler where you removed the hanger
7. Apply Penetrating Oil to all 4 bolts. Wait awhile - I waited 1 hour
8. Carefully remove all 4 bolts with the box end of a 10mm wrench
9. Slide shield back on top of the muffler
10. Replace each nut and fender washer - secure the shield back in place
    
    
    
11. Reattach the rubber hanger from the muffler to the chassis

Nice fix!! Mine doesn't have this yet but will be good to check when under there doing exhaust work.

Nice write-up. I had the same issue and did the same fix last summer.

Are ramps necessary for this job or can it be done just from the ground?
