So it appears my rear subframe is in a bad way and will need to be replaced, I've read as much as I can but there's a real lack of the usual guides and videos, is it really that difficult of a job?

I can only find really crusty used ones or a new one so I think ill have to go new and replace all the control arms at the same time and I've seen this one on ebay which I think will ok https://www.ebay.co.uk/itm/11606007...bc7NcycTm6&var=&widget_ver=artemis&media=COPY

Any tips, from what I've learnt so far diff will need to be serviced with fresh oil at the same time and the haldex unit, u was also going to get 4 new bolts for subframe is that sensible or just wasting money?

We'll wait for @Hippo and @GrumpyGel to see this as they are the peeps in the know(ish) ...

I can't help really.

I got my local garage to replace my FL2’s rear subframe last year. New bolts are essential as is getting your 4WD alignment checked when the job is done. Good idea to slap some underbody sealant around while your under there.

Yeah I plan on giving it a good going over with waxoyl whilst everything is out, want this to be a one and done job
Does anyone have a part number for the diff bushes where it bolts to the subframe that's one part I'm struggling to find, 2.2 diesel manual
