I have noticed a rattle noise at around 50-55 mph when driving. Sound like marbles rolling around a tin can. Sound like it's coming from drivers side. It seems to be more frequent now but have to turn the radio down to here it good. I have no ideas of what it could be. I have 126,000 miles and I hope it's not going to give me trouble with only this many miles on it. Any suggestions?

do you have step bars? something might have came loose in them, and this the rattling you hear.

I do but they're pretty tight and it sounds like it's behind the instrument panel

I think it's turbo related. I have had that very faint rattle where you almost wonder if its there or just change in the bin haha. Only mine is passenger side. Very faint. I have noticed it for about 100,000 miles
