After a recent regular tire rotation and balance, my vehicle steering felt shakier than normal. Had rotation and balance checked again, but problem continued. Thought an alignment might rectify the problem but was informed this was not needed. Went to my regular mechanic and did notice the steering vibration. Found that it had to do with the forward bushings, and provided me a copy of a service bulletin issued by Subaru dated 6/20/18, #05-63-18R addressing this item, and also provided me with a video and picture of the problem to provide to Subaru repair. Since the Subaru dealer that I went to was not interested in repairing with the information provided, went back to my mechanic and had the work done. No more vibrating steering wheel.
