it was totally unexpected. no sound problems, nothing. it just happened, and u could feel ur car shake. i was going up hill, pushing it. plus i was driving it for a while on a hot day

. but yea, at a red light, you will heard a loud clanking sound, metal against metal. very loud and very annoying.
i dont kno how you can tell if its about togo....especially because this is such a vital component. but yea, i guess im looking for $1k in repairs.
