Rear Leaf Springs Replacement

After 120K and nearly twelve years, the rear springs on my Capri were in bad shape. The car was sitting very low at the back, so it was time to change them. This job is quite hard work and you may have problems with some of the fittings as they are constantly exposed to water and mud during their life. Assuming you have got all the bits listed below, you should allow a whole day to change both springs.

Before you tackle this job you must have obtained the following: new set of springs (the Capri Club sell uprated springs for £85 + postage), new set of U-bolts + nuts (this will set you back another £25 from Ford) and a 7/8" 'recessed' ring spanner (by that I mean one where there is a 90° bend at the end of the handle). This is the ONLY type of spanner that will fit the nut on the front spring bolt due to its awkward location. Have a look before starting the job - you will see what I mean. DO NOT be tempted to try and reuse the old U-bolts and nuts that clamp the spring to the rear axle. All eight of mine sheared when I tried to undo them.

First loosen the rear wheel nuts and jack up the rear of the car using a trolley jack on the diff. You need to place some axle stands on the chassis - try the box section just forward of where the front of the leaf spring is attached to the car. Once these are in place lower the jack slowly; the rear axle will drop down until the springs are in their resting place. Place some bricks under the diff to stop the axle dropping to the floor when the springs come off.

You are now ready to remove the springs. The LHS is slightly complicated by the presence of fuel tubes and the exhaust, so you may want to start with the RHS first. Spray everything to be undone with plenty of WD40 before you begin. Start by undoing the nuts holding the rear shackle assembly together. I had no problems with these. The shackle should twist apart leaving the end of the spring free. Now tackle the front of the spring. I had major problems getting these bolts off. As I explained earlier, you will need a 7/8" ring spanner with a bent end (not the flat types) which will just fit inside the small access hole and over the nut. Now using a 5/8" spanner or socket on the bolt try turning - the ring spanner will lock against the metal freeing your hands up. I found the bolt was very hard to turn because the rubber bush had corroded onto it. Eventually with a lot of huffing and puffing the nut should come off. However it might still take some considerable effort to get the rest of the bolt out. Keep undoing the bolt and slowly but surely it will twist its way out. With both ends of the spring undone, you can undo the nuts on the 4 U-bolts. Use a large socket wrench with a 16mm socket. I guarantee that they will all snap which actually speeds the job up.

With a bit of pulling and tugging, you will be able to remove the spring from the car. Rescue the fittings from the centre of the old spring and transfer them onto the new one. Spend some time cleaning up the nuts and bolts and apply copper grease to the length of the bolt. This will prevent seizing problems in the future. The new spring should be attached front and rear first. This is a lot easier to do than the removing stage! At the moment, don't bother tightening up the bolts fully.

The next problem is to re-attach the centre of the spring to the axle. Simply use your trolley jack under the front part of the spring and slowly raise the spring upwards. Make sure that you have fitted the metal and rubber parts from the old spring. To help with the fitting, cover the topmost rubber pad with some copper grease. You may have to tug on the axle a bit to get it aligned, but eventually you should be able to jack the spring into place ready for clamping. Attach the new U-bolts (copper grease on the threads) through the lower clamp plate and fix the 4 nuts on. Tighten them up slowly in sequence making sure that the same amount of thread is visible on each. Eventually you can torque them to 20 pounds foot (repeat several times until all 4 are properly torqued). This is not the final torque setting that should be done at the end with the car on the ground.

And that is the first side completed! Once the other side is finished you can attach the road wheels and lower the car down. All the bolts should now be tightened and torqued to the correct level with the car resting on the ground (Rear = 9 pounds foot, front = 28 pounds foot & spring U-bolts = 25 pounds foot). You will be amazed at the difference in ride height - my car is at least three inches higher at the back end! I found the car felt very solid and smooth afterwards. It was a very satisfying job to tackle despite feeling a bit stiff afterwards!
