I drive a Cadillac STS Jg. 2005 4.6l V8 rear drive For a long time I have lost an oil in the front left of the shock absorber. Although I only have 86’000km on it For me it means to replace both front dampers. Now at GM Parts Online I have selected the part number of the front shock absorber for my chassis number and namely GM 19181634 for 355 dollars. If I now look for this number at Rock Auto the system gives me 3 different shock absorbers at below Monroe 39135 for around the 88 Euro. I would like to decide for this because from my point of view completely sufficient. Now to the bellows, which one should also change immediately, does not cost much, I have 2 to the choice the delivery. At the more favorable stands: front; rear wheel drive; except magnetic suspension control. At the more expensive stands: GM 88957131, front; “soft ride” suspension (option code FE1) At the top of the damper dome, where the 3 screws of the spring leg are located In the middle of the screws is an electric plug (under the hood ). Now my problem is that I do not find out if my car has a “softride” suspension or not. According to English Fooren I have read that the option code sticker is in the spare wheel dump, which I also found, there are numerous codes executed on it, but nowhere of “FE1” Hassi number is by the way 1G6DC67A550230248. If someone could help me, I would be very grateful 😉
