This was a very easy job to do and would take about an hour.
1. With the car on a flat level surface (mine was outside) chock the wheels.
2. with a trolley jack I jacked up the off side, with my jack as far back on the chassis as I could and I then use wooded sleeper of cuts (9"x6"x18" long) to take the weight of the car.
3. check it is safe.
4. I took off the rear off side wheel.
5. Undue the shock absorber bottom bolt from under the car (Not the nut as that is welded on !).
6. remove any parts of your broken spring, make sure you keep the top rubber mount (Mine stopped in place) and the bottom plastic part that the spring fits in.
7.make sure you get the new spring (mine cost £45 from CES ltd motor factors ) around the correct way. fit the bottom plastic part (I temporarily held mine in place with some insulating tape).
8. If you want to have the same number of Fingers when you finish the job, I griped the spring with a large pair of 'Mole Grips' to insert it to keep your fingers out of the way in case it slips.
9 Now we have to get the wheel hub down nearer the floor to get the spring in (With out using a spring compressor ) For this I used a wooden old fence post 3"x3"x 6 foot long, place the end above the brake drum and under the chassis, I got my wife to gently push down on the end sticking out to the side of the car. Only push it down to the rubber flexible brake pipe is about straight and No more.
10. with a bit of washing up liquid on the base of that plastic part in the bottom of the spring to help it slip in (not Grease),
From under the car holding the spring with the mole grips insert the top of the spring in to it's mount, then with the help of a 18" screw driver just ease the bottom of the spring into it's housing, note the plastic part has a lug to fit in to a locating hole.
11. with a small screw jack I jacked up the wheel hub so I could get the shock absorber bolt back in and tighten it back up.
12. put the wheel back on and lower the car down on to it's wheels.
13. test run Jobs a good one .
I did find the location of the hole (a week later) it was still there so I noted it's location and took photo's and video so I can claim off the council.
