We had the timing belt/water pump replaced in our Toyota and 2 weeks later in our Subaru. Both started making the same short squealing noise when the steering wheel is turned sharply (like backing out of the driveway and starting down the street) within 1-2 days. I’m thinking no way is this a coincidence - any ideas before I go back to my mechanic?
The drive belt that operates the power steering pump is probably not tensioned correctly. These belts should have been replaced along with the timing belt. They had to be removed to get at the timing belt.
