Strut supports

'01 Camry, LE, automatic, 85000 mi, 6 cyl.
Had begun to hear a change in normal road noise. Took car to my regular mechanic ( NOT A DEALER ) who advised that the struts were bad and the tires cupped. $ 1300.00 later the noise was back to normal and the car rode very smooth.
After about a week I noticed that when the steering wheel was turned hard to either side I heard either a rubbing noise, or a clunk, or both from the area of the right front wheel.
Went back to the service guy who road tested the car, put it up on a lift and finally advised that the strut mounts were the cause of the problem, that they " believed " that it was not something very bad or dangerous, that I could have the mounts changed for $ 250.00, or not have the work done but simply get used to the noise, and that - in response to my question - this had nothing to do with the replacement of the struts.
Are they right?
