Bartruff1,

Inside the rubber boots is grease. Grease is made of soap and oil, Soap is used to hold the oil in place. If you are seeing a drip of oil, which given enough time will make a 3" diameter discoloration on cast aluminium you may have no issues. If your boots are not split, forget about it. Beleive it or not 80% of the grease in cv joint never sees service, how would it nothing pumps it in there. The grease is spun around any by centrifugal force the oil gets seperated from the soap and by capilarry action finds it way out.

As far as the rear end leaking there should be a drop or two every now and then, it keeps the lip seal lubricated. If you aint getting drops on your driveway every single time you drive it you do not have a problem.

If you do take it somewhere make sure they dont try to take you for a ride.

By the way buy GLD hold through september and sell, statistics shows it goes up 5-7% in September every year since 1993.

I just got back from a 3k mile road trip with many high speed runs - 120+ mph - across Montana and Wyoming. I bring this up because I have found three quarter coin sized puddles of fluid that looks like it may have come from the pinion seal(?). Thinking maybe the pressure build in the ring and pinion housing at high speed may have caused this leaking that showed up on my garage floor when I got home. A short trip across the Island and back showed no continued leaking from the rear end area. Should I not worry about this??

That almost sounds like it may have been overfilled, pull the plug with the car level and it should be at the bottom of the hole. Trust me when you are driving it is a shower of oil in there. I have not seen but imagine there is a breather on top to vent any pressure. make sure it is not plugged. If you check the level and it is fine dont worry, if you check and it is low add some and watch for drops. I would hate to get into the rearend.

I have been buying that white lithium grease and it really reduces the pain...the dealer here has two kids in college thanks to SPF 2811, he has a picture of it on his desk. A gold spider.. never have done that...I am heavy into Annaly Cap Mgt (NLY)... commercial real estate in selected high end markets...pays 16% with a PE of 9...
