OK...I found the lube point on the front driveshaft, I purchased a needle attachment for my air-powered grease gun, and I pumped about 10 shots of grease into the thing. No grease escaped anywhere around the U-joint.

So how do I know when I've put enough grease into it?

 

When it squirts out of the front diff vent!

Just kidding - I'm jealous that you found yours...

 

I did mine last weekend, I think that I got 6 or 7 shots into it. I noticed that the grease starts to come out on the other side of that collar that youre shooting grease into once its full.

 

I wondered the same thing put about 4 skirts in and went to go check it two days later and it had flung the excess onto the bottome side of the truck. I guess that was a sighn LOL.

I found that the grease point is easy to locate by looking at the getnal or and there is a # pressed in it the #8 I just move the truck till its on the passenger side look int the drive shaft and there it is.
