When should I replace my harmonic balancer?

[sn95jones]

I just remembered today our Sn's were pretty common for the pulley to go back so I inspected it and from my point of view it looked alright, engine doesn't vibrate and the car drives with no vibration either here's a pic anyways you guy's tell me.

Thats a pic of your crank pulley, we need a pic of the harmonic balancer which is behind this pulley, normally the hb has a rubber and if you can see this coming off it then you should change the hb.

Ah well hmm alright then but isn't that the rubber piece in the pic? Either way @ 87,XXX it should be alright, right? I know the ball joint boots are ripped, not horribly but I need to do something about them before they do get bad. What do you suggest?

When mine failed the rubber was falling apart on the back of balancer, check that out too, but if you don't have any vibration I'd say your good to go. Changing the HB isn't really that hard anyways
