Pro tips- The cage has a flat end and a tapered end. You want the flat end to point down.
The star holes are more open on one side. That is the side you want to point up.
Press/pump grease into the center hole of the bird until you see the grease pumping out around balls

Graduate level BIRF training = thank you Dr. LCP!
When greasing the installed BIRFs is there a rule of thumb for how much grease should be put in?

I use 3 tubs/tubes total - 1 to fill the 2 birfs, 1 tubs for each cavity
Note: You do not need to disassemble the birf to service. I just did one of the two to look at the condition/wear of the inside of the birf.
I guess this means you’re not getting the RCVs

I would not make that bet just yet
So… need some group thoughts. My ‘93 is coming due soon due to leaky seals. It’s got a long birf/flange on one side and a short birf/flange on the other. Neither of them has never even thought about clicking but they’re at least 50k miles old. If I’m going to all the trouble of a front end rebuild should I keep them and refurb them like this and swap sides/get new flanges, or just get completely new ones? I’m definitely on the fence about it.
Unless you rock crawling with 37 or bigger drop those bad boy in a 5 gallon bucket with some diesel fuel clean them up and slap them back in with fresh grease 
35’s and mild wheeling. I like the way you think.Unless you rock crawling with 37 or bigger drop those bad boy in a 5 gallon bucket with some diesel fuel clean them up and slap them back in with fresh grease
