I have a vibration at about 45+ mph it gets even worse when i give it gas too. I have checked these things:

the u-joints are fine
the shocks are new
i changed the driver side lower control arm bc the bushing was destroyed
theres a new tb
new tranny fluid

The only thing that I can think of is maybe the rear end is going bc the vibration as hard as i can tell is its in the rear of the car

I have no idea whether this is causing your vibe or not, but I just cured a nasty vibration by changing my clutch and resurfacing my flywheel.

You're sure it's speed-related, and not rpm-related?

The balancer vibrating would be brought on at certain rpms rather than at certain speeds...correct?

it can vibrate anytime the engines running usually not as noticable at idle etc and more at higher rpms but yes its from vibrations but it would seem tobe at certain speed if it wasnt really noticable downlow
