How to replace the shock absorber in the rear suspension on Cadillac STS?

The first step to replace the shock absorber in the rear suspension includes removing the trim panel before moving the sound insulator from the shock tower. Disconnect the electrical connector from the F55 suspension before removing the F55 shock absorber mounting nuts. The vehicle needs to be lifted and supported properly by following appropriate techniques. The automatic level control air line must be detached from the F55 shock before unscrewing the three shock bolts where the vehicle meets the body. The new shock must be properly positioned following fastener precautions for new installation. Attach the lower shock mounting bolt into position then tighten it to 150 Nm torque (111 lb ft). Connect the automatic level control air line to the shock of F55 suspension before you lower the vehicle into position. The upper shock mounting nuts require a torque of 25 Nm (18 lb ft) as you install them before reconnecting the F55 suspension electrical connector if necessary and placing the sound insulator around the shock tower and finally reinstalling the trim panel.

How to safely service and repair the front Shock Absorber on Cadillac STS?

Start the front suspension strut repair by establishing safety conditions because gas charged shock absorbers operate under high pressure; do not sever the shock until all gas pressure drains out and put on safety glasses when center-punching and drilling. A centerpunch should be used to create two indentations measuring 50 mm (2 in) from the top and 25 mm (1.0 in) from the bottom of the tube. Place the shock absorber in a vise where the rod extends fully horizontally. The 5 mm (3/16 in) drill bit will produce a hole through the first indentation to allow gas or gas/oil mixture escape while shop towels capture the oil. The second hole requires the same 5 mm (3/16 in) drill bit to be applied at the second indentation point. One should use shop towels to contain the escaping oil. Use a drain pan beneath the shock absorber as you support the piece by its holes while manually moving the rod through the tube to empty all the oil.

Serving as an intrinsic part of the construction of any car, this element reduces shock impulses that are translated to the driver to contribute to better ride comfort and control. Through the technique of dissipating kinetic energy as heat, the Shock Absorber specifically controls sudden suspension oscillations, cooperates with springs for the purpose of controlling oscillation. The shock absorber arrangements incorporated in Cadillac STS models include twin-tube and mono-tube shocks vary in characteristics, as follows. Twin tubes shocks are preferred on their simple structure, while mono-tube shocks provide a faster heat removing capability and perform as multi-position mounting.
