Thanks to Jim C we got these done in a few hours while he moved Mount Land Rover around his driveway. Found the seals had been improperly installed causing water ingress (needed to be 4mm deep, they had been installed flush). Brakes where fine so we put them back in. Wiggle on the tire was gone (finally).
Also that drive flange is a great all in one tool for fitting wheel bearings!
Need to do the rear brakes for sure (felt a lip on the rotors) but those are the easy bit.
