Went to suzuki 3S today ,A worker (MR BABER) thoroughly checked it and said that the bushing of control arm is OK ,It's just the outer rubber that is cracked ,nothing to worry about it..
then i asked him to check ball joint boots,after examining he said that there is no evidence of grease leakage or crack and he said that as far as grease is intact in the boot , u r good to go..
Moreover he advised to get it checked again at 30K schedule Maintenance which is due in a couple of months.
