What is the procedure for greasing the ball joint in the rear trilink? I was thinking a grease needle through the ball joint boot and was wondering if there is a better way.

That would be the only way to grease it; it's a non-serviceable unit, meaning there is no zerk/grease fitting. Any reason why you feel the need to grease it, because if there is excessive play in the BJ, you would need to replace it.

Here is a writeup, TonyCRD did:

The ball joint doesnt have excessive play. I have found that by adding grease to non-serviceable ball joints helps extend their operating life since the factory grease has dried up after a year or so.

Does Moog make a greasable ball joint for the tri-link?

When I had my rear suspension out I greased it really good.

I took the ring off holding the boot on and cleaned it all out really good. The grease still looked ok but there wasnt a whole lot in there. I pumped it full till the boot was plump and put the ring back on the boot. Should be fine for a good while.

Also did this to my tie rod ends but I just couldnt get it to work with the upper balljoints on the a-arms. The boot was really tight and I was worried it would rip. Ive got a spare stock a-arm so if one gets some play in it Ill swap it out. I was able to clean the spare a-arms boot out since it was off the Jeep so it would be good to go for along time if I did need to use it. Only reason those balljoints fail is b/c of the lack of grease..
