I've just replaced the lower wishbones on my 2007 147 JTDm, I don't know what all the fuss is about!
I didn't use a ball joint splitter or remove anything else to remove or fit the wishbones...
I detached the upper drop link from sway bar, you can leave the lower one intact. I also took all the btake and sensor lines our of there secuting mounts so they have more flexibility.
Remove the ball joint nut.
remove the lower strut mount bolt.
Put a jack under the wishbone at the lower strut bush and jack it all the way up until there the drive shaft has clearance issues with the lower strut.
give the ball joint a shock with a bog hammer on the flat surface of the hub, is easier if wheel is turned out. Of that doesn't release it give the balljoint a hit on the end of the threaded shaft, place a solid nut on the end to protect threads etc. It will pop and drop very easily.
then remove the four bolts securing the inner bushes of the wishbone and wiggle it out.
Refitting is nearly oposite.
first maneuver wishbone into position, inner bushes on or near their mounts, best to come in from the front a bit behind the inner wheel arch.
then jack it up a little to get the ball joint in place, fit nut and tighten.
then jack up the hub from under the ball joint, whilst giggling the inner wishbone mounts onto there seats, jack up the hub will lower the inner bushes flush onto there seats, insert bolts, I was able to screw all four in by my fingers so no chance of cross threading.
then lower the hub slowly until the drop link is lined up and fit it back in.
continue to lower the jack until the lower strut bolt holes are lined up and bolt it up.
fit the brake and sensor lines back into there clips and fit the wheel. Win.
there is a bit of maneuvering the lower strut fork around but it's strsight forward.
I've not worked on suspension like this before but it was only 15mins to either fit or remove per side.
Hope this helps.
