Rattling Noise At Rear Of Gen 7 Celica

[NorbyG]

I’m getting a rattling noise at the rear of my generation 7 Celica. When car is driven over any rough surface (small and large cracks, holes or bump) in road the rattling can be heard; but on smooth surface it’s not noticeable. I've taken absolutely everything out of boot, including all plastic panels, as after listening properly, I noticed the rattling noise sounds more of a plastic rattle. Also took back seat out to see if anything has been left anywhere by previous owner that could be rattling about – didn’t find anything. Replaced all the plastic panels, cushioned with foam rubber, but rattle still there... Got my mate to sit in the back to find out exactly where rattling is coming from. He said it sounded like it was the tailgate – left side; but we checked it out, inc. spoiler, but couldn’t find anything loose. I noticed the rattling started suddenly (next day or so, after the night) when I hit a hole at a speed bump.

You could try checking the road springs in case one has broken. A heavy knock can break them especially if they are quite old.

Possibly the heat shield on the silencer.

Spring ok.

Do you mean heat shield over silencer, that's bolted to underside of car?

Try tigthening up the car jack. These are know to rattle when they loosen off a little.

Car jack was the very first thing I looked at - took it out and left it out.
