G body shuffle

Hey guys its been a while since ive posted. Ive got a problem with the ss that keeps getting worse! It started off as a little bump-steering and has gotton dangerious! After a spirited blast down the hway yesterday somethings got to give! A little background on the ss. 5.3 t56 aftermarket upper arms in front and a body rear with southside machine arms in back. Now its gotten so bad when the cruze lets off the gas it wants to take off. I caint see anything moving in the front end after getting under it several times. I have all new moog front end parts. Maybe i have a crack somewhere? Ikn where to look. Any suggestions? Im at my witts end.
Thanks
John

Check for a broken rear LCA mount at the frame.

If you feel anything in the steering when you let off and/or get on the gas, it is most likely in 1 or more of the 8 rear suspension mounting points.

And yes, it will feel like bump steer, because the steering changes with obvious front end rise/fall.

This is REALLY exaggerated on IRS cars.

How about this!!!

That explains why it got progressively worse.

SSM bars are bad for doing that.

It's not a popular opinion around here, but thats one of the reasons I am not a fan of A body or fox body 8.8 rears in G bodies. Sure, it was the late 70's in detroit and cocaine was a hell of a drug, but there is a reason the suspension geometry is the way it is.

Now it drives like a whole different car!! I think next im going with a 9in with weld on brackets. Idk if the 8.2 will hold up to a built 5.7 turbo motor ive been planning!
Thanks again
