copied and pasted off another forum so that i dont need to type lol. this is for a mercedes A class but the technique is the same, offcourse ignore the refitting part as that's specific to the merc.
Ensure the handbrake is on fully
Block the rear wheels
Position the vehicle jack on the jacking point, front O/S or N/S.
Slacken wheel nuts of the wheel, on the side you are going to work first, bearing in mind that drop links are replaced in pairs.
Raise the vehicle only sufficiently to able to remove the wheel.
Using a second jack , place it under the wishbone( i.e. directly below the suspension)Using a plate, or piece of wood as necessary to protect the underside of the wishbone.
Raise the jack until the drive shaft is horizontal with the car, This action will raise the Ati-roll bar, and drop link bottom fixing point thereby taking pressure off the drop link, both top and bottom.
Slacken and remove the drop link fixing nuts, Top and bottom (observing points made above)Note leaving the drop link ball joints under pressure did not stop the spindles from turning in their housing
The old drop link should fall away from it's fixing points.
Re-fit the new drop link ,ensure the nuts are fully tightened to 60Nm
Gently lower the jack from beneath the wishbone
Re-fit wheel, Torque wheel nuts to 110Nm.
Repeat procedure on the other side of the car
Enter a record of replacements in your service record book (I use a page I have fixed in the back of the book)
Incidentally it is worth saving a couple of the gaiters off the old drop links! If when working on the car you damage a gaiter on a track rod end or wishbone lower ball joint you can then replace it without having to buy a new unit.
