The cv joint boot is not leaking. I sprayed it with armorall as a help until I can get some rubber renew on it. I don't know what is involved with a boot replacement, but I am sure it is a bit of work.

Anyway, are you saying that the whining could be the CV joint? I know they can crack snap and pop, but I didn't know they could whine.

Could it be the diff whining, and if so, what can be done except replace it? It does look like it is leaking from the front seal where the drive shaft enters, but when I checked the oil level, it wasn't low.

Thanks.
