All cylinders in E-Class convertibles should be rebuilt once you notice the first leak. The original seals are about 20 years old now, which is far past their expected service life. The decay of the seals is a chemical reaction that is governed largely by temperature and exposure to water content in the hydraulic fluid. Top Hydraulics' seals are resistant to water, and they are chemically much more stable than the original seals.
For Rebuilding Your Cylinders: We gladly accept the cylinders in their locks / latches at no extra charge -- you save the extra labor and we have all the assurance that the cylinders do not accidentally get scratched upon removal from the locks.
Seals used by Top Hydraulics, Inc. include Viton™ and Teflon™-hybrid seals, as well as enhanced Polyurethane material, which far exceed the OEM's requirements for rigidity, but provide at least double the service life for your convertible car top actuators, based on scientific test data.
In some extreme cases, P/N 1248000072 can have corrosion (rust) on the chromed shaft, inside the cylinder tube, or inside the gland. We need to treat this on a case-by-case basis, the same as deep tool-inflicted scratches on the shafts or inside the gland. If we can polish out the damage, then there will be no additional charge. If we have to replace metal parts, then we need to charge for that. For example, Top Hydraulics manufactures hardened, stainless steel replacement shafts for all W124 cylinders, and we can replace all but the 1248000072 glands.
