hey i have a very worn out aircon bearing in my eb 5.0litre and wanted to know if any 1 has replace 1 before if so is it easy or just tricky needs to be fixed as the noise is annoying the s**t out of me

If it's the front "idler" bearing it's easy. It's a standard NTN bearing. But make sure you measure the clearance between the clutch and driven plates before you dis-assemble. They need a specific clearance.
