| Polyurethane has been with us as a specialised plastic for some thirty years. However recent advances have now made it possible to engineer very special properties into this exciting material. Suspension bushes are some of the most highly stressed components fitted to a motor car. They undergo enormous strains and in the most arduous of conditions with no maintenance or lubrication. The material they are manufactured from is a rubber compound containing natural products which deteriorate with age. It becomes softer and more pliable, resisting the forces placed on it less and less. Therefore allowing more and more movement of suspension components and offering less and less control over the suspension geometry. This in turn causes accelerated tyre wear, braking instability and poor handling. This is the single biggest reason you can instantly tell the difference driving a three year old car compared to a showroom new one. However even new cars will benefit from POWERFLEX bushes because of their superior design they offer much more effective control of the suspension components to a much greater extent than normal rubber items. |

| 1. A blow torch may be necessary to burn the old rubber bush out of the arm |
|
| 2. Using a tube, a socket and a vice it is often easy to remove an old bush like this. |
|
| 3. Some bushes have a metal outer sleeve which will always need to be removed. Push or burn out the old rubber, the outer sleeve is then clear to see (top left picture), then cut the metal outer sleeve along its length with a hacksaw. | ![]() |
| Cut until the saw blade becomes tight. This means you have cut through the outer sleeve and the tension has clamped the blade. | ![]() |
4. Bushes with a flange can be chiseled out (especially useful on Escort mk 5, 6, 7). |

| 5. Some more difficult bushes can be removed by drilling through the outer sleeve. | ![]() Left picture - drill through the outer sleeve to cut it and relieve the tension Centre picture - cut only the outer sleeve Right picture - bush will now be easy to cut out |
