What was the previous cost of replacing the bush? Mine is clunking increasingly but doesn't show cracking yet, I am hoping it will be cracked in the next 6,000kms before its next service. I'm going to be close to the end of my factory warranty at the next service so I would rather have it repaired at the end of the warranty period. I'm just wondering on the previous cost as I am sure I will be doing it again the next time it fails.
