I seem to be spending a little to much time under my 308 recently, but while I was under there I thought I'd give the CV joints a little inspection, since I could tell that they seemed to be "slinging" some grease out. From under the car I could see the grease was coming out of some small holes in the rubber boots. The joints that are slinging grease are the inner/transmission end joints, the holes are at the shaft end of the boot, and are about 1/8" diameter and appear as if they are supposed to be there. Forgive my ignorance, as I know very little about transmissions and CV jonts, my question is, is there an inner seal that has failed causing the grease to now be expelled from these "weep" holes? I cannot imagine that this loss of grease is normal, is it? What can I expect as far as repair/replacement costs? Is this a DIY project? Again any information is appreciated - Thnaks is advance...
