I believe that the inner CV joint on my front right axle needs at the very least to be repacked with grease and rebooted. I'm wondering whether it needs something more. I am experiencing a noise on acceleration and when the drivetrain is under load. I suspect it is what many have called a vibration in related threads but I experience as more of a whine or hum. I'm virtually certain it is not a bad front wheel bearing but it sounds similar. (I replaced the left front bearing 8k miles ago and am familiar with the change in the sound when banking left and right.) I also just replaced both rear wheel bearings, thinking/hoping they were the source of the sound but the sound remains and has grown louder over the past weeks/months. I suspect the inner CV joint because 5-8k miles ago I noticed grease on the right LCA and the top surface of the splash guard. I couldn't localize the source at that time and basically ignored what I'd found. Subsequently I noticed the grease again when pulling the splash guard for an oil change and radiator hose replacement. I have now localized the source to the outer edge of the inner CV joint. It's almost as if the grease is leaking out under the edge of the boot where it's clamped down. I know, it doesn't really compute but that's where I see grease and it matches the grease splash pattern. Also, the boot itself is fully intact. I'm wondering whether I can now get by with seeking to repack the joint and place a new boot--as is detailed in a few other threads--or whether I need to replace the entire axle unit or possibly have it rebuilt, though I am not familiar with options for having that done.
