grinding noise from front right wheel

[castigan]

all bushes have been lubed... mechanic has been under there are says they are fine.. then he tells me the noise is just suspension creaking... its driving me nuts.. its really a hard grinding noise... and i think its wheel bearings.. but the mechanic says you would hear the noise all the time if it was, not just when on the brakes....

This may be the same issue as originally posted, but I haven't tested the powerwashing or reversing methods yet.
It's very hard to recreate the noise as stated previously, and the VX doesn't make the noise all the time. Also, it doesn't seem to be limited what speed i'm travelling except that if it doesn't start grinding/rattling from a complete stop, then it won't start making noise after I have begun accelerating/am up to speed. Any help is much appreciated thank you!
