I have a Mk3 Mondeo and there is such a clunk from the rear end every time I go over a bump so I intent to change the subframe bushes. I have purchased a set of Powerflex polyurethane bushes s0 that there is apparently no need to disconnect the suspension. Has anyone done this? Any advice welcome. Does the rear need to be jacked up with wheels off the ground...if so can you jack up one side at a time? Alternatively can it be done with the rear wheels on ramps?
