Replace harmonic balancer??

Replace harmonic balancer??
Has anyone replaced their harmonic balancer on a 4.6 or 5.4 (i'm assuming they're the same)?? Any tips to doing it or things I should look at/replace while I'm at it. I've had a strange rpm dependent chattering for awhile and it seems to be coming from the harmonic balancer. I also started to notice a slight vibration at idle a couple of weeks ago.

I have replace mine (4.6) because I could see it had a wobble in it. Figured I do that before it took out the crank bearing or something major. As for tips i would check/replace all the pulleys too. Buy a fan clutch wrench set, harmonic balancer puller and a breaker bar if you don't have these.

Don't buy it if you don't need to I hate to say it but auto zone has a nice fan clutch tool and puller set for cheap with there loan a tool you basically pay to rent and they reimburse you when you return it but you should definitely have a breaker bar but the pulleys should all be replaced along with your tensioner because they seem to go far more frequently then anything else

Did you guys have to remove anything to make it easier to get to the balancer??
If not I'm thinking I should plan 1-2 hrs for the balancer, 3-4hrs if I do all pulleys. Sound right?

Skid plate, Flywheel inspection cover, Plastic rad cover thing, fan and shroud. Plan for 4 hours then you have lots of time if you run into trouble
