Replacing the front suspension components is a pretty straightforward job if you've got the right tools.
Most of the effort goes into undoing seized up nuts and separating the ball joints.See here for some ideas from my previous car.
In order to get the ball joints apart, a separation tool is required. The image on the right shows two such tools. The lower one cost £15 at a tool shop. The top one cost £47! at a motor factors. Is the price difference worth it? Yes. The expensive one works straight away whilst the bottom one requires 3 or 4 goes and a lot of heating/hammering etc.
Pushing the front rubber bush into the control arm can be interesting. The force required is not great but it must be continous. If it is removed before the bush is in the correct position then it'll come back out. I used a bench vice and a piece of tube that was just a bit bigger than the OD of the bush as a spacer. Otherwise could use tubular spacers and studding, bit like what I did on rear suspension. Top tip here is to use some washing up liquid as a lubricant.
I found the shocks to be in pretty poor condition. One of the front ones was leaking. Back ones were rusting away nicely.
With the rear springs and dampers, the trick is to support the car on the
jacking points. Pieces of wood should be used as spacers to prevent any damage to the sill. This
way the entire rear axle can be lowered by undoing the top fixing
nuts of the shocks. The springs then fall out.
Top tip getting track rod end nut done up without turning the whole joint can be difficult. I use a woodworking G clamp to hold the parts together as I do the nut up.
