  1. No lube is a (repeated) maintenance failure. Grease should be applied (unless tech data otherwise directs, that caveat would matter but I've not seen nor heard of same in decades fixing fighters ) until it displaces old grease out the pin/trunnion interface.

  2. Jet mech of decades here (USAF in various AFSC, I'll spare ya my CV). Grease oozing out the joint between shaft and trunnion bushing means the fresh lubricant properly displaced the old grease in a perfectly normal manner. When you are not an aircraft mechanic it would serve you better not to express a non-professional opinion but look for information instead.

  3.  @Palmstreet-u7x  Lubricants are rated for their use. One cannot get "too much grease in a confined space" in a trunnion pin/bushing interface. Any excess pushes old grease out the sides. "Heat" is not an issue in the very slow speeds (a landing gear trunnion pin never turns even one RPM because it's in a fixed position) involved but galling due to not being lubed/lubed properly can be.

  4. It's possible to just keep pumping grease because the end goal during lubes is to force old grease out. I've done MANY landing gear lubes (mandatory after aircraft washes in the USAF) and while I'd be curious (and inspect the adjacent area as expected during all inspection and maintenance) if the tech doing the lube had no idea of the aircraft's history that would not be hard to miss for someone used to applying fresh grease than wiping off the extruded old grease.
