Grab a sharpie and draw a line on the body around the solid bushings that you installed so you have a reference where they were.
Go drive it, give it a hard accelleration, and then go easy on the brakes, check it,
Go drive it, brake hard, then don't accelerate hard, check it,
did they shift from where you first marked them?

edit:
Also when you installed the bushings, did they fit tightly in to the subframe, or did they go in easy with a bit of movement?

I'll do that. I marked a line on all the bolts. I'll do as you say tomorrow. It just started raining

2012LS3VERT · 01-20-2017, 07:56 PM

That was going to be my suggestion. If the bolts are at least at 120 lb-ft or so, the cradle shouldnt be moving.

camarosspower · 01-20-2017, 08:34 PM

I put some liquid grease on them to help. I had to press them in using the jack

camarosspower · 01-21-2017, 05:54 PM

Omg. Don't tell me I put them upside down???

2012LS3VERT · 01-21-2017, 07:05 PM

That way is correct.

camarosspower · 01-21-2017, 07:34 PM

Yea I quickly looked pics and felt better. So I took out the bolts held the cradle in place with a jack. Put loctite on the whole thread. Tighten them just like you would a wheel. First basically hand tight then tq to 100, then tighten them up real good. About a 1/4 turn more. Marked the diameter and a slash on the bolts. Now to test it

Rob@WretchedMS · 01-21-2017, 07:45 PM

Hard to tell from the pic, but the 3rd picture looks like it was moving. The 2nd a bit too, but the 3rd more so.

2012LS3VERT · 01-21-2017, 08:16 PM

Yes, it either moved a bit, or that is where the stock aluminum sleeves were sitting. I generally go to at least 145 at least, a M14 grade 10.9 bolt is generally torqued to 165 anyway, they wont fatigue at 145 or so. Marking them and watching is probably the best course of action.

camarosspower · 01-21-2017, 08:37 PM

How can ya'll tell it moved? I wiped the lips so that it would show on the pic that it's sitting flush. Just drove it and I'm still getting the same rear movement.

2012LS3VERT · 01-21-2017, 09:10 PM

Still not sure its moving. That is why we suggested drawing around where the bushings sit against the frame.

camarosspower · 01-21-2017, 09:18 PM

Doesn't seem like it's moving

2012LS3VERT · 01-21-2017, 09:27 PM

We meant at the top where it meets the car side, like the first set of pictures. It wouldnt move at the bottom.

camarosspower · 01-21-2017, 09:41 PM

Oops sorry. I'll get it done. Just a thought. Could it be possible that my OEM differential bushings aren't doing their job anymore? It only does it under hard acceleration. Normal driving everything is good
