It'* odd that they did that. They should be so tight that no movement is happening.

...my last phrase was "installed correctly" Something is not right if you have to grease them to make the creaking quit.. I'd look deeper before I just juiced them up with wheel bearing grease... Personally, I have NEVER had them make noise.. and I have replaced dozens of these things. Mike

I spent enough time smacking my head near them when I was doing the motor. So I figured I'd have them replaced when my trans was done.


As for greaseing the bushings I've always been told to do it; I've never heard or seen any ill effects for doing it so I figure I minus well.

I believe that the bolts are 12mm, 1.75 pitch. Length is probably around 5"

Good luck finding them somewhere other than a junkyard or dealer though, since they're hardened bolts with a collar on the hex head. I tried Lowes, Home Despot, Napa, Autozone, and ended up at the junkyard. The junkyard is my friend.

they are very cheap through gmpd also, like under $2/per

Thanks! Since I work in a Machine shop I have a guy I can call about hardware like that. I'll see if he can get me a good price on some.
Otherwise I'll get all this stuff off of GMPD or the dealership.

Pull one bolt and measure it with a ruler and a thread pitch gauge. Or test fit a nut until you nail it.

I had thought of that but given the state of the bushings and bolts I wanted to get my info from here before I tried to pull a rusty old bolt.

Oh yeah, I should mention: Be careful removing those bolts!

I went to remove one of mine (the washer had rusted right out from under it), and it broke loose just fine, but then it got to some rust at the end of the bolt, and snapped off. It had rusted to about 1/2 of it'* original diameter.

To make matters far worse, it was the rear-most bolt, which has no top access to it'* captive nut, so I had to make access. It'* fixed now, but what an ordeal to just replace one stinking washer.

I think that if I had been careful, and gone backwards on the bolt occasionally when it got tough (to clear the threads), I could have gotten it out without snapping things. So... I just suggest that you be careful. PB what you can.
