couple questions @robxstone What is the intermediate shaft?

@z34 what are the diagonal braces?

its so hard to tell exactly where its coming from. sometimes i'm sure its front passenger side but sometimes it seems to sound a little bit in the center of the front end.

I have been thinking its unrelated but there are a couple other noises. One is that Ive just thought one of the rear hubs is bad because there is a rotational sound.....it gets louder the faster the car goes and it has a rhythm to it. I jacked the car up and there is absolutely no play in any of the wheels in any direction--and I violently shook the car. Since I've replaced both cv's and both front hubs it can't be those. The noise has remained throughout. The ride is a bit wobbly, if that is the right way to say it. kinda feels like unbalanced tires. But all four tires are brand new on straight rims and they are balanced. Had the same thing on two other sets of wheels. The vibration is in the floor, not the steering wheel.

Another thing is at times in lower gear the car kind of wobbles or shudders a bit, like it would if weight was shifted or something. That's the best way I can think to describe it. this you can feel in the steering wheel.

One other idea ive had is that maybe something is up with the subframe. Arent there bushings where it connects to the cars frame? That's the popping noise, not the rotational noise. maybe could explain some of the apparent weight shift phenomenon. I've replaced the dogbones, though not with brand new ones but visually apparently better ones (off another car). The rubber is good and not too flexible. I've also replaced the lower motor mount and the trans mount looks good. I would suspect it was replaced when the previous owner had the transmission overhauled.

The popping noise is just a random noise but does not seem to happen at higher speeds.
