just hoping for a point in the right direction, but whenever i go over a speed bump or even the slightest bit of uneven road the car makes a noise like metal hitting metal like a constant rattle.if the road is smooth i hear nothing but it is really starting to grate on me.ive had the drop links changed but it is still there.i was informed that it could be the ARB bushes and was hoping someone could let me know if theyve had this problem and if so what size bushes do i need and how much would it roughly cost to get them fitted and where is the best place to buy them.thanks.

Heavy metal on metal knocking is likely to be the lower ball joints, a light metal on metal knocking/tapping is likely to be track rods or track rod ends.

or the radiator banging about due to failed bottom mounts??
