Just keep adding a little every few days. I think that is the only way unless you want to take them apart to make sure there is grease all the way down to the seals. If you see any coming out of the seals already then it's there.
In answer to the last poster, I installed Opentracker roller perches on the daughter's car when the new UCAs whet on so there is no way it was the perches. I don't think the rubber kind would do that either since they basiclly don't move, unless they are oder and the metal tube part is starting to separate from the saddle. I've seen that happen. Then if you tack weld the saddle to the tube and your UCAs are older it may crack them at the mounting hole. That is exactly why the daughter needed new UCAs.
