Further to my last post regarding wheel wobble, it turned out to be the low Power steering fluid, as someone mentioned, thanks. .

I topped it up and the wobble stopped, but now the fluid is absolutely pouring out the cap, its bubbling like a kettle in there. Its been leaking out the cap for months, so I thought...sod it...leave it till it reaches a happy level...but no...it caused the afforementioned problem.

What could be causing this?
