: Which rear shocks do I need? 2004 Deville

07-16-10, 10:59 AM
I have a 2004 base Deville with the FE1 suspension option. I need to replace the rear shocks, but the parts I found online don't look anything like whats on the car, the part number i found is ac504123 but that looks like a strut not a shock.
The shocks in my car have a flange on top with 2 bolts that go up into the body, and a big bolt on the bottom that goes through the lca and the bushing in the shock, there is also a small air hose on them for the compressor.

thanks for any help

Had the new shocks installed today, AC Delco 504-547, $101 ea plus $75 labor, $305 all together with tax. These are only for cars with the FE1 rpo code (Soft Ride Suspension)Also, not sure if the mechanic bought them or if they came with the shocks but he also installed new upper mounts.

Made a huge difference in the car.

I figured I'd post the numbers here in case anybody else is looking.
