I am going to install zerk fittings on my calmini UCA's tommorrow. I have read all the posts about doing this, but is there any last minute suggestions from anyone?

Just one. Mark the alignment fittings exactly before you remove the UCA's, replace them in those exact locations, then, when you're done, take it in for an alignment. You will probably still need minor adjustments.
It is a very worthwhile mod
PS One more, use stainless zerks.

Got the new black bushings on and the zerks in. Not a squeak. Thanks for the advice.
