'92 SC400 sqeeling noise

I have a high pitched squeeling noise only at around 40 miles per hour. Under or over 40 it goes away. It happens about 15K on the tach. Anyone ever had this problem? Thanks

Yeah do you have a motor cycle in there?lol Check the tensioner the spring inside it might be taking a crap. Making the belt squeal that or is there fluid leaking on it that would cause a noise.
