Grease from CV Joint

My 1994 Ford Taurus SHO is slinging grease from the right side inner CV joint area, but there is no tear in the CV joint boot and the clamps on either end 0f it are intact. How can this be? Is it possible that heat from the exhaust can force the grease out, but not melt the boot? Other ideas?

Grab the CV boot and give it a squeeze. I bet you get a handful of grease.

I have seen grease liquefy with age. If you have slung the grease out, but the boot is still intact, you can get just the boot replaced. Do it soon. It will not last without lubrication.

Tester, you are correct. Found small tear I had not been able to see. Thanks!
