Hey guys, lately i have been getting a clunking noise from the rear drivers side of my VR. It sounds like a stuffed CV in a front wheel drive car. Being IRS i think this may be the issue. The CV's have never been changed and the dust covers have never been off. Is it possible that the CV's might be dry? Do you guys think that changing the diff oil and packing the CV's with grease may help? Thanks in advance.
