Note that there is a significant amount of labor involved in removing and replacing (R&R) the hinges on a Z4 top, and that both hinges always fail (leak) at almost the same time. It is close to the same amount of labor to R&R both hinges compared to R&R of a single hinge. This makes it highly inadvisable to deal with only one hinge at a time. Top Hydraulics' rebuilds make your original hinges much better than brand new ones, on account of the far superior seals used. Usable service life expectancy of Top Hydraulics' rebuilt hinges should be over 30 years under normal circumstances, with a 3-year warranty.

These hinges are actually very well made; only the OEM seals decay over time. Top Hydraulics replaces the leaking seals with material far superior to OEM quality.
The rebuilt & upgraded cylinders (hinges) feature new and greatly improved rod seals, piston seals, gland seals, and port seals (where the hydraulic lines go into the cylinder). The service life should be at least 3 times as long as with the original seals, under similar circumstances.
In rare cases of excessive damage from previous DIY repair attempts, Top Hydraulics may refuse to work on your parts and refund your payment.
