Roaring 1988 300 SE

Hi everyone,
Car has approx. 138,000 miles on it. Has a slight roaring sound while moving down the hi way. Seems to increase with speed from about 20-30mph to around 60 or 70. Is constant, even through shift changes. Also markedly more noticeable when slight steering pressure applied to left. Applying pressure to right and roar almost completely dissappears.
Any ideas out there amongst you good folks as to what I should look for. Changed right engine mount yesterday. Left engine mount is ok. Two brand new tires on front, rears 90% tread left.
Thanks for help in advance.............
