Default Shaking under acceleration (not axle)

So I've started experiencing a shaking when accelerating, the higher the rpms with more violent the shaking. I've read the results from searching and I came to the conclusion that it was the passenger side axle. So i replaced the axle today and sure enough the problem persists.

now, while i was under there I noticed just how torn up my control arm bushings are. the passenger side is completely thrashed and not really even intact. could the bushing be the cause of this shaking while accelerating or is there something else I should consider?

new bushings are en route. im hoping this fixes things. I just didn't imagine worn bushings would cause shaking intermittently like this. thought it was the axle for sure.

Bushings can cause the vibration but did you check the condition of your tires? possible bent rims or rim. If you have any unsual tire wear you need to have the tire replaced and the alignment checked. Also the front tires might need to be balanced.

i have not actually remedied this problem. I thought it had been fixed when i replaced the control arm bushings. I was wrong. Sometimes it shakes violently when accelerating and sometimes it's subtle. But its most definitely still a problem and now a whirring sound is coming from the front drivers side.

I'm guessing the stock clutch that has been in there for the 90,000 miles is starting to hurt. After all, this did start happening after the D44 install and the WOT pulls that come with a new turbo.

even if it's throttle specific?

it doesn't shake at all when in neutral and cruising. its ONLY in gear.

I can't say that it pulls any harder than it usually did. However torque steer does pull it to the right if i hammer the gas with the turbo spooled.

I have an 03 with no LSD, for the record.

so clutch doesn't immediately come to mind when taking all the information into consideration?

I just want to cover all my bases. it does have 90+ thousand miles on it and this all started after some spirited driving with the D44.
