Thread: Horrible scraping, rattling sound.

if its coming from the rear and only when moving it could be wheel bearings or a brake backing sheild only a guess tho you might need some mechanc to help source the cause

yep Id agree with that it could also be something inside the backing plate.

If it was something behind the backing plate wouldn't it do it first up, when cold?

Could also be a uni joint

The vehicle doesn't drive or feel different.

if its something behind the backing plate it will be loose and moving around so could happen at anytime

I think you need to take someone with you on a test ride so they can help isolate the source of the sound. It could be any part of the drivetrain, brake calipers/ shields or hub bearings. Have a good crawl around under the vehicle in good light and check those brake shields and the driveshaft uni's. Check the oil level in your diffs too.
Good luck.

I had a noise like this once in the Pig. A fairly loud rattle was heard (I thought) from the front left corner of the car but when the brakes were applied it went away.

Took a mate for a drive to find out where it was coming from as I'd looked everywhere and couldn't work it out. He said "It's coming from the rear left"

Took the rear left wheel off and low and behold the disc had sheard off from the hub! The brake pad retaining plates had dissapeared and one of the pads had moved into a vertical position and dropped down onto the edge of the disc, worn a groove and eventually worn through the disc.

Part of the pad was still held in the caliper though, so when I pressed the brakes they grabbed the disc and of course the noise dissapeared. When I let off the brakes the disc was rattling around in the caliper and spinning freely on the hub.

Check your brakes.
