You remove your cylinder(s) you would like to have rebuilt, and send them to us. Core exchange (where we send cylinders from our inventory first) is available only for full sets of eight cylinders or for the Front Latch Cylinder. Core exchange is $200 plus $250 refundable deposit. The deposit gets refunded in full once we receive your core without significant damage to the metal parts. There is no surcharge for dented or corroded cylinder shafts - shaft replacement as necessary is included in the rebuild charge. Consider having all eight cylinders rebuilt & upgraded at the same time because they all fail in fairly short order, and you save a lot of labor and frustration this way!

This is a rebuild/upgrade service for a single '03-'09 Cadillac XLR Header Latch Cylinder for the folding top system, p/n 88957089. Also known as 1536-030-B or 1536-030-C or 1536-030-D (engraved on the cylinder in the second row of numbers).
The original seals in these cylinders are made of a material that falls within 10-15 years, or faster if exposed to contaminants or water in the convertible top hydraulic fluid. Top Hydraulics replaces the original steel gland inside the cylinder with a new, CNC-machined one that accommodates a more sophisticated rod seal, gland seal, and wiper seal for the maximum service life of the cylinder. Replaced and improved rod seal, piston seal, cap seal, gland seal, wiper, and port seals make this part better than a brand new one, with an expected service life of 30-50 years under normal circumstances.
In most cases, the first leak on the original cylinders will be through the mounting hole at the bottom of the cylinder, making it appear like a leak from one of the hydraulic hoses. Next, they will typically leak from the top, and ultimately they will develop internal bypasses. Even brand new cylinders from the dealer can fail again within a short time frame if the hydraulic fluid in your system is contaminated. The rebuild & upgrade service from Top Hydraulics will avoid these issues because our seals are inert to almost any contamination.
