Hydrolastic displacers are generally very rugged, reliable and long lived. However when originally manufactured few people would have expected them still to be in service 45 years or more later. Very often the hoses become weak and perished, especially around the ferrules. These eventually rupture causing collapse of the suspension on the side of the car concerned. More often than not there is nothing else wrong with the unit and it would be capable of many more years service. The problem is that the hose is integral within the unit. Previously units were simply disposed of and a replacement fitted. The units have been out of production for many years and they are getting more difficult to find.
The good news is there is no longer any need to dispose of a perfectly good unit just because the hose has ruptured. We offer a quality re-hosing service for your existing displacer units. We use brand new hoses which are much stronger and durable than the originals. A new threaded union is fitted to the new hose. View prices for our hydrolastic services here.
The hoses we fit are of the same diameter as the original. After fitting the displacer unit is thoroughly pressure tested in our test rig. The diaphragm is carefully examined whilst under pressure for the minutest of fluid leaks. It’s not very often we encounter a defective unit, but if do we’ll let you know straight away. You can either send us another unit, or purchase one from our stock. If we encounter a defective unit there is no charge for that particular unit.
