I have been experiencing grinding (from the left side of the car) during hard accelerations from 1st to 2nd gear and also clicking noise when at full lock (to right only). I had a quick look under the car and noticed some grease spraying marks although none of the rubber boots looks torn. And i also noticed something abnormal, the right side drive (longer) shaft appear to be thicker (in diameter) when compared to the left side. Is this normal?

Would like to know this before deciding to only replace CV Joints alone or complete with drive shafts (if its got the wrong shaft). Any recommendation for a local supplier for CV Joints / Driveshafts?
