    Hey all, not sure where to put this so here we go. I'm rebuilding some Rokmen uca's with heim joints. Is there a particular lube to use or am I going in dry? Opened up the inspection plate and found what looked like remains of a liner and corrosion. Throwing new joints in, but obviously want to prevent this as much as possible.

    Yes
    Those cover plates are a double edged sword because they trap moisture in the uniball which expedites corrosion. If your new uniballs have a ptfe liner then you should not lube them with anything but dry teflon lubes. The key to longevity is just keeping them clean.

    WSSX16T. Seems like the liner gave up the ghost as there is some play. I live in Southern Indiana, so corrosion is a concern. I'm thinking after replacement to run some dry Teflon lube to keep it "wet" so to speak?

    as far as pressing in new uniballs into the cups on the arms, I don't press them in dry

    I'll drip a little 3-in-one oil, engine oil, shock oil... or similar lube on my finger and give the inside walls of the uniball cups a little coating, and a little on the outside of the uniball body, then wipe any excess clean once pressed in.

    I've used anti seize and it works fine too but it's usually a bit thick and messy
