I have a 95 Gt Vert that has 65k miles on it. I am slowly upgrading items on it that need to be replaced anyways. I have already lowered it and put in steeda x2 ball joints and MM 4-post caster camber plates. IMy most recent upgrade was Blue Oval upper and lower control arms with polyurethane bushings and now I hear a howl from the rear end. The noise occurs at all speeds but increases in volume as speed increases. It still has the original gears.

Could this be a vibration that was always there but I could not hear because of the stock rubber bushings or did I change the angle of the rear end and something is not correct anymore? I measured the new control arms before I installed them and they seemed to be the same.

Have you checked your U joints? and are the upper control arms adjustable?
Also make sure everything is good and tight.

Most likely the polyurethane bushings are transferring more NVH into the cabin.

I was thinking either u-joints or a bearing somewhere. The control arms are non-adjustable and everything is tight and greased.

Ok then it is your bushings any time you stiffen the car with poly its less forgiving as far as comfort goes but it helps a ton with handling.
