I've made a batch of diff flange pullers to suit the Discovery 300tdi's 3-bolt rear diff flange. They're basic but solid, and available for £10 + £3 P&P. Pictured below prior to getting a coat of paint. Works with an M8 bolt to pull the centralising pin out of the flange, revealing the flange retaining nut. Ideally apply some heat beforehand to soften the threadlock as otherwise it's possible to strip the thread on your bolt.
These are a cost-effective alternative to the official Land Rover tool LRT-51-008 (about £170, for no obvious reason...). Sure, you could make something to do the job, but this will save you the hassle for not a lot of cash.
