Intermittent grinding noise when in gear slowing down, not brakes as was using engine braking. It stopped soon as power was reapplied. Think was induced with stop start in traffic. Stopped making noise after I pulled over to take a looky look underneath.Checked UJs and there was abit of play so require renewal but don't think that would make grinding noise but I don't know what symptoms of uj's except think major slop Clutch feels fine but noise was coming from that general area. Clutch was renewed 2 years ago and done around 30,000mls with light duty use. I did hear a metallic noise as if I had dropped a bit of metal plate when leaving my street earlier on. Any ideas
