05 Corolla making metal noise, hitting bump

Check your shocks really good, it maybe the rear strut mounts are bad, or somthing in between that is damaged, rotted, or just worn out.

Hello
need help with Corolla 2005.
05 Corolla making metal noise, hitting bump, or wavy spot on the roads.
Sound caming from the bottom, it's like metal pipe hiting something.
When I push down few times rear end of the car, I heard metal klicking
caming from bottom in the middle of the car.
Exhaust looks ok

Rear shock and spring Ok.
sound caming from midle or front, when I shake car in rear end.
When i driving it sound from trunk, or from bottom rear seat( First I chesk a trunk - nothing loose)

Making a online diagnosis with minimal information is like mind reading. Please give huge amounts of info or one better video problem and post online youtube. It does sound like the struts or the strut mounts. If your car has over 90,000 its time to change out those struts anyway. Just for fun look at the front struts and see if your dust boots are torn up.

Look underneath my Corolla, adn see right side of metal sheet (ander rear seat) -loose!!!
Is it fuel tank cover?

Is it a thin aluminum shield? if so that might be an insulator. After that, your description is very vague and I think may be to difficult to diagnose in this forum.

May be aluminum, it's grey color.
I check repair manual:
no insulation underneath
only "Fuel tank protector" on 5 bolts

Don't know without seeing the piece, sorry.

sounds like the heat shield about the muffler if not would be t he exhaust rubber mount lose

Take it to a mechanic and have them drive it, maybe they can pinpoint what the problem is...we cant do that for you here without actually looking at the car.
