3000 miles and 2 months ago, I had the rear lower arm bushes replaced on my Skoda Fabia front suspension. I asked at the time whether any other work could or should be done while the suspension was disassembled.

I came as a shock when the MOT (3000 miles and 2 months later) showed that the front lower arm bushes need replacing.

Is it reasonable that this is the case?

Would the wear on the front bushes have been apparent when the rear ones were replaced?
Could the new rear bush show up wear on the front bush?
Could the replacment process have disturbed/damaged the front bush?
