Well I was doing the first service on my quad today and wanted to great the suspension components. Just bought a grease gun and went to grease the relay arm on the rear of the quad, I had to push it on and tried giving it a few shots of grease and it wouldn't take. I wiggled it back off and much to my suprise part of the zert came with it. Looks like about two threads came off with the head of the zert but the remaining threads are still in the relay arm . Any ideas on what I can use/do to get the remaining threads out and put a new zert in???
