Harmonic Balancer question

Can anyone tell me how difficult it is to change the Harmonic Balancer? I just bought a 2000 C5 and noticed the H/B has a wobble....thanks.

It's not very difficult, but make sure you get a new bolt and don't use the old one.

I believe you need to remove the steering rack and many have not been able to remove the old bolt without a very strong impact.

Hey just a tip you might as well go ahead and replace your ac belt tensioner and AC idler pulley while you have the rack out.

you will thank me later. You may also consider and underdrive pulley as a replacement instead of the stock piece.

Could quickly turn into a nightmare if you do not get full thread engagement, and end up stripping threads of breaking off a bolt.

use or make a proper pulley installer, do NOT use a bolt to pull your balancer on

Its not a bad job but you need to have the correct tools otherwise it can turn into a disaster very quickly. As others have stated, follow the GM procedure and don't follow the methods of LS1howto.com or you could end up in the "stripped thread club". You can rent a removal tool from Autozone to get the old pulley off. You should replace the seal as well that is in the timing cover. For re-installation, make a tool like I did or one of your own design. If you have an automatic, then a tool to hold the flywheel will also be required.

These cars are actually very easy to work on with the right tools and taking the proper amount of time for the job.
