Scania cab mounts

Morning all.Hope everyone is staying safe and the ones who are still working congratulated for all that you do to keep the country running.
The question I’m hoping someone can help with is.The company I work for has just bought 5x 2015/16 Scania R450 units.One of them has can mounts at the front knocking badly.Looks like a torsion bar across front.Just wondering how easy these are to do and do I need to suspend cab etc or any tips on doing them.
Thanks in Advance.
