Grinding noise when turning - linked to engine speed (see video)

[key_lime]

Hi all,

I have an early 1997 5 speed manual.

My car has developed a horrible grinding noise when turning left @ RPM > 1500 !

If I turn at any speed with low/no RPM I get no noise.

I'm thinking it could be engine/transmission mount related, but unsure.

If I open the lockable center glovebox (above the shifter cables), the noise gets much louder.

Please help!

Thanks,
