l also wanna change the discs and pads on the front axels

Starting with the Discs & pads, remove the wheel, use an impact driver to remove the cross head screw that holds the disc in place. Then using a flat screw driver spread the pads as far apart as possible (Force the screw driver between the pads & the disc, leaver the screw driver to push the pads away from the disc). Remove the two bolts holding the brake calliper in place, remove the calliper from the wheel hub. Remove the two anti rumble springs (Note how they fit). Remove the brake pads & replace with new pads.
Apply a light smear of copper grease to the back of the new pads.
while the brake cliper is removed change over the brake discs, replace the cross head screw with new screw & tighten with impact driver.
Compleat the reverse of the strip down procedure.
Its unsual for the wishbone bushes to fail, check first that its not the tie end rods or tracking control bushes.
If it is the wish bone bushes, take a small car jack & place it under the wish bone, let the jack take the weight of the wishbone only. Loosen the bolts that hold the two clamps on the wishbone, loosen the jack enough to allow the two bushes on the wishbone to be removed. Replace with new bushes & re-assemble.
N.B. Check the level of the brake fluid in the brake fluid header tank, make sure that when u force the pads away from the disc that the brake fluid does not spill over the top of the tank. Also use course sand paper to rough up the new brake pads before fitting them,
