The white bushing in the middle should be bonded to a roundish plastic piece that is hidden behind the metal flange that is bolted to the firewall. As these mounts age, the plastic disintegrates and the rod, with that white bushing, separate from it. (The stuff behind there looks like 20 year old snot, IMO) The textbook answer is to buy a new one and wait for it to happen again. I have used fiberglass reinforced bondo to replace the almost golfball sized piece. I have also been taken to task for this seemingly temporary repair- but it has seemed to work for 2 years. There are probably better ways to repair it than what I did. Use your ingenuity, if you wish.
