Since I'm having the timing chain and gear set replaced, I decided to also have the balance shaft gear set replaced at the same time. I went ahead and ordered an AE Clevite set from AutoPartsGiant.com. Since the whole right side of my engine is going to be coming off anyway, would it be worth my while to also have the entire balance shaft assembly changed out at the same time? A bigger question is, "What is usually the average life span of a balance shaft?" I currently have 222800+ miles right now. I can get the balance shaft from a local Buick dealership's parts department. The balance shaft is sold with the bearing. The cost would be $111 plus tax for the part. I might need to also get an expansion cup plug and retainer as well.

Unbelievable! GMpartsdirect.com is selling the balance shaft and bearing set for only $66. I went ahead and bought it there instead.

I dont have a balance shaft in my engine, so I know nothing about the shafts. I wish I did though, my 3.8 vibrates at idle like every other SFI...

Yeah, about knocks your teeth out!

LOL It's NOT that bad! Your motor mount/s are bad, that's all.

And nice deal on the balance shaft.

Shush, quit making me feel bad about my car

Your car definitely rocks over mine, Adam. I still have a few more things to do even before I begin to work on the outside appearance.

We kinda went opposite, I went body first and engine second, you're going engine fist, body second.

Yea...same here...whenever I get around to it. Mechanical first, then body.
