Default Crank Pulley Vibrating

Hi Guys,
I noticed that my crank pulley is vibrating. I would like to replace it with an aftermarket stock sized crank pulley. Which shops sell these? can you please provide a link to it?

What else should I change while I'm changing the crank pulley?
ac belt
main drive belt
ac belt tensioner
main drive belt tensioner
arp crank pulley bolt

car is an '02 Z06 with 50k miles

how much would a shop charge to change these parts? I'm pretty close to The LAPD.

thanks

Replace it with an ATI super damper. You will never have trouble again. This is an excellent product 100 times more advanced than the GM version. http://www.atiracing.com/fallsale/fs_damper.htm

Labor varies shop to shop. But it should take about 5 hrs. for a tech that has done this before. Right tools and lift it is not difficult.

Good Luck!

Like said above ATI has some nice stuff. Labor rates vary from shop to shop. you have to remove the steering rack to get the old pulley off and on.

can someone tell me which part number the pulley is? There are several different kinds on their website.

I would like to keep the car stock for now, plus i need to pay it off first.

edit: do you change just the tensioner pulley or the whole assembly?

Usually you replace the whole assembly for the tensioner.

thanks to cajunmech for the PM response


one more question:
I noticed it only vibrates at idle, it goes away when I rev it.

should I worry about it and change it ASAP?

I don't want to spend the money to change it if I don't have to.

It doesn't go away, the harmonics change with the rpm and the dynamics change. However the vibrations will wreck an engine. Go to the ATI web site and research the FAQ and tech articles. Information is power.
