Have just done this today and it is relatively straightforward.
Mine is a 2012 and has the rivets which I will replace.
They seem like a tight fit but it is possible for the subframe to move up and down on the bush.
I used the Meyle HD bushes which fit fine.
As has been said before a 24mm ratchet spanner is a big help.
The only tip I have to add is that if the bushes are stiff coming out rather than stress the tool just apply some heat to the bush housing and this helps reduce the friction.
Glad I did mine as they were starting to debond from the metal core.

Has anyone had a good experience of a garage that could do a good and reasonable job, as my 2006 FFRR is mainly strong and well worth preserving, but having read all your excellent posts, and being realistic about my limited time, space, and skill, any recommendations on a garage that could get my RR back end returned to full operating capability would be hugely appreciated please? Noted earlier comments re EBay subframes costs too if I need to go that far, as have some frame welding a couple of years ago, so the rots sadly started Current wheels:
2006 RR S/C (+ chipped + Bespoke S/S Sports plus exhaust)
1985 Defender with V8 4.2l conversion
2012 Aston Martin DBS Volante

I’ve just been quoted £3,000 plus VAT by Safari Engineering at Eversley…
I’m not sure if I’m confident enough to start heavy engineering in my garage under axle stands… if I muck it up I either break the car or kill myself! 2012 L322 TDV8 Vogue SE: Buckingham Blue

not diyable for everybody but 3k is taking the absolute .

are they sure they've quoted for the right job? Its actually a sport

Not anymore, 4.4 TDV8 now

In fairness that is to include the annual service and a couple of brake pipes (although I need to query that too as I only did them in Feb 2022 so surely they should last longer than two years?) and they are saying it's a sub-frame off job. 2012 L322 TDV8 Vogue SE: Buckingham Blue

I dunno then, to me it's still a lot unless LR parts are expensive af. I know the pipe and it is awkward but dropping the subframe if your a professional shop isn't that hard Its actually a sport

Cost of parts including new bolts and washers was around 950 euros through my garage. Labor another 600 and another 100 for the special tool. All parts were genuine LR.
