Took my wheel off today because I noticed grease splatter on
The rim coming from behind the wheel.








My driver side is spotless, but passenger side has thick globs of grease all over.
I know the boot has grease on it looking like it's leaked but some is from
Me running my finger around it looking for a split, I never found one

 

Its cv boot grease. Will last a long time unless you get water in it. May just have a pin hole in it. Change the whole axles when ya have the time and money to do it. It will make a clicking noise on turns when it runs out of grease. I have seen these last a year like that!

 

Ok thanks, I was gonna ask next how long I could let it go for. I won't have time for a week or two maybe even a month the way things are going. I've also been getting a shake starting at 60mph on up to 80, in guessing that a wheel is out of balance but could it possibly be due to the axle?

 

Let me add, when I say it has a vibration, I mean it goes from a slight vibration to violent shake. It also seems to get worse on a right curve but almost goes away completely on a left curve.
Speed limits are 70-75 on the hwy here and it's bad from about 60 and gets a little better at 80

 

Grab each axle shaft and try to shake and move it. If there's any play in it, replace it, the CV is shot.

 

Yep that's it. Has about an 1/8 inch of play in it and the drivers side was solid. Thank you all for
The assistance, gonna swap it out after work tomorrow
