F20 Cluster replacement

[Dod]

Ok, I've one of these to do quickly tomorrow morning, can someone talk me through it? I know with a bit of time I'd manage it myself, but time is against me tomorrow. Taking her good self for her 4mth scan and forgot I've a box to build for collection tomorrow. lol

Or is swapping the duff diff for a good one an easier option?

Would have said swapping diff would be easier dod.
