would you know if it is a reverse thread on it ie open it clockwise or do I need to use an impact spanner on it
I did soak it with WD40 but still unable to dislodge
thanks in advance
No, they're both the same right hand threads. Use an impact wrench. It's not unusual for them to be on tight. Iusually put mine on with a ratchet and snug them up good, but it's always easier to remove them with an impact.
