Terrible Vibrations, Front Wheel Options

[3SGTE]

Over the last month or so, i have noticed a clunking/knocking noise from the front passenger wheel when turning slow or parking and turning the steering wheel, but when on a long journey home tonight, i was driving at 60mph max and just taking my time, when ever i took my foot off the gas i got a really strong knocking vibration from the passenger side wheel i think and vibrating towards the middle, hard to tell as i was driving, strange thing was though, that it only happened when my foot was off the gas!!

Any ideas?? front drive shaft, or could it be something to do with the 4wd drive shaft system??

That is my best way of describing it, any questions and ill answer them best i can.

that sounds plausible too. but a bad motor mount would cause hard shifting wouldn't it?. notice any strange shifting as well?

I just happened to have a similar vibration at speed with another car and it turned out to be the ball joint. unfortunately these things have a tendency to be elusive -_-
