Mitsubishi Colt CZC 2006 DiD Auto 5 door - Replacing Wishbone Suspension Bushes - Vinnie

Very loud and solid sounding clunk from front passenger suspension and on checking, the rear-most rubber wishbone bush seems to have a lot of lateral movement when the wishbone is prised with a suitable bar. The anti roll bar bushes/links have just been replaced both sides.

How big a job is this for a competent DIYer in my drive please? Are any Special Tools required, tips on getting the old bush out & new one in, does the whole wishbone have to be removed or can the bush be replaced in-situ please?

Any help most appreciated.

Thanks, Vinnie.
