Hey guys I have a 2005ls2 Bought the car about two months ago Left it in the driveway started up and noticed some chirping noises Long story short I checked everything from tensioners two belts And lastly Alternator Every time I did something it worked for about two days and then came back I'm hearing about the defect in the old fives of the harmonic balancer Can anyone tell me what to do next

You will see the balancer wobbling if it is bad.

AC tensioner pulley is a common point of squeaking.

Billyac

The balancer is wobbling but my mechanic shored me that it was fine But I'm guessing he could be wrong what I tell my mechanic to do two test

dev1360

There will be some slight movement of the balancer. If it is bad, it will be obvious. If you are in doubt, check YouTube for videos of the wobble. The labor is pretty hefty if it needs replaced.

Billyac

Well I am going to wait till Monday and take it to Kerbeck And see if that is the problem I also put my hand on the bolt on the balancer and I actually can twisted off by hand Do you think we placing the bolt is possible

dev1360

Oh boy. If the balancer bolt isn't on, you have a problem. It is probably wobbling pretty bad.

Bolt is torque to yield, and needs to be replaced. They are $6 at the dealership.

Don't drive the car.

Billyac

I wont drive it Thanks for that important advice last question So I should try replacing the bolt first... ???
Before trying to balancer??? Or since I'm all up in there should I just replace it all

Billyac

Or is replacing the bolt a crazy question.. Lol

tennblkc6

you will need to replace the balancer and the bolt. do yourself a favor and do a search and read up on it so you are in the know. do not replace with another oem balancer and bolt.

Billyac

The I will do that... So you don't think replacing the bolt is even an option??

tennblkc6

from what I've read...nope...not an option.

Billyac

Hey thks for all the help if car fall under that TSB well the dealer do it for free!!! N if not How much you ballpark Kerbeck for doing the job

EVRose

TSB repairs are not free. Recall repairs are free. The dealer will probably put the revised bolt/washer on it and check for severe wobble. If there is none your out the door. I would not want another GM balancer if its bad.

Billyac

Are they going to charge me for putting On the bolt???

Billyac

I would Like to give this job to my mechanic Who is great But From what I read it doesn't Look like an easy job And I don't want to embarrass him by axing him do you think you can handle it cause I've known him for a very long time Can anyone tell me what to do Should I just man up and pay the extra money and have it done by professionals

EVRose

Well yeah. Dealers dont work for free ya know. Plus the cost of the bolt.

Billyac

Lolol I know that... Someone told me because of the TSB that some dealers will do it for free I heard it was due to the machine putting to much or not enough torque on the bolt... It's a shame so many people have to suffer for their mistake!!!
