Odd one this...

Driving to work this morning I noticed a knocking noise coming from the back of the car (boot) when going over the uneven roads near my house .

It basically sounded like a large loose box moving around in the boot.. however there is nothing in the boot. I noticed when putting some weight on the rear suspension I can hear a metallic pinging noise, any ideas?

Bust spring maybe?

Scrabble under the back of the car and have a butchers.

Could it have split one of the top suspension mounts?

Agreed; that sounds very much like a busted spring or split top mount. Easiest and best to inspect the rear springs on a 4-post lift.

let the wife out of the boot?

Cheers, indeed looks like nearside rear spring/mount.

Chuck it up on ramp tomorrow to have a look... I assume I wont destroy car driving on it.

Gently, and no further than necessary. Apart from possibilities of spring through mount or falling out if the car goes really light over a crest, the corner weights and rear roll resistance, and hence handling will be all to ****!

Well had it up on the ramp and it actually looks like the rear anti roll bar I had fitted...

The bolt from the bar is knocking the existing on the left side, I guess I'll see if the garage I had it fitted at can cut the bolt down a bit.

All sorted

The bolt from the rear arb was sitting too close to the existing which runs through the shock and it looks as if it had worked its way loose.

Put a spacer on the new bolt and tightened it all up and its good to go
