On a core 4x4 front LCA (tier 2) does the adjustable end (with the JJ) go on the frame end or the axle end? I set mine at the frame end with the grease zerk pointing up as I do not want the zerk wiped out and wanted the smooth end for less chance to hang up on. So was I thinking right or did I have a brain fart??

The JJ should be on the axle side. And the zerk fitting should be facing down for easy access to add grease.

The JJ/adjuster should go to the frame, zerks should face up to protect them from rocks.

Do JJ's have grease holes on both sides of the adjustment side? That can be a issue if holding a length and it ends up facing down. You can run it like that or remove the zerk and cap with a set screw. Or give both arms a half turn to face up. (Arm may need to be dropped to grease)
Iirc my first set of TF arms had 2 grease ports. I put set screws in both, removed and greased easily with a zerk in place.

only had zerks on one side. Pointed them up and will pull the bolts and drop them down when its time to grease. I do like the idea of the set screw though. As long as you did not damage them it would be easier to pull and replace with zerks then pulling bolts.

Why do you need to drop the arms to grease them ? I have Synergy lowers adjustable, and i have enough clearance to do the job every 5k miles or so without any issues, and my zerks are all perky pointing up :), i cannot picture the issue, unless you mounted the JJ in the axel ?, can you change the zerks and go with 90* ones ?
Greased them 2 days ago, and it may not seem like it, but my grease gun fitting goes in there without any drama.

talked to CORE and they said it does not matter, they usually run the JJ on the frame end as it stays cleaner.

on the CORE 4x4's I do not think I could get my grease gun in there. I will probably swap them end for end like I wanted them to began with. I do like the idea of the 90degree zerk though if I was going to leave them that way.
