This "clam shell" cylinder is mounted horizontally inside the large rear deck lid frame, and it is responsible for locking part of the deck lid frame. To remove the cylinder shaft and/or the cylinder bottom from the top frame latch's ball joint, you need to pull up the retaining spring by inserting a flat screwdriver into the back side of the female ball joint part. Before removing the hydraulic lines, please retract the cylinder shaft. This pushes more fluid back into the pump, plus it prevents accidentally slipping tools from damaging the polished shaft.

Model years 2006 through 2009 have seven cylinders that actuate the retracting hard top and its latches. All cylinders are very similar to each other, and it is hard to tell which one will fail first. The decay rate is generally a function of temperature. The biodegradable seals inside make eventual failure of all rams almost certain, unless the car gets wrecked prematurely. We offer a package deal for all seven cylinders to be rebuilt for $1100, as well. 

You remove your hydraulic cylinders you would like to have rebuilt, and send them to us. Core exchange is NOT available for Pontiac cylinders. The polished cylinder shaft must be undamaged for a proper rebuild.
