Sorry for not posting the info, it is a 1998 PA with 47,000 miles on it. Bering are tight an free all new brakes. The sound is heard when driving it is a slight buzzing sound only when making a right turn. Wondering if it is in the power steering, it is not a fluid issue as it is full an clean. It started after an ABS issue was finally fixed at the local Buick dealer ship. Link to other issue below, which was not a happy experience!!! That is what has me thinking about the EBTCM.
ABS/Traction control issue
