Suspension, Brakes and Tires Discussion, Strut Piston Comes Off in Item Specific Cadillac Discussion; Thats a reasonable plan.
You will know if there is unequal dampening, it can be a scary out of control ...
I am replacing it with a new Magnaride strut, I just can't afford to both right now. I'll see how it goes once I get the new one to determine how quickly I replace the other side.
When you are finished with the job, inflate the tires to 34 psi, COLD, and do a test drive: On your way to the rural country roads, check the front end dive and stability. Does the nose drop evenly upon aggressive braking ?? Does it rise evenly upon aggressive acceleration ? Out in the boonies, find a straight stretch of road that will allow you to do a long series of shallow S-turns at about 35 - 40 mph. Does each front corner dive the same amount from right to left turns ? You should be able to make RADICAL changes in direction (S-turns) with very little nosedive, body roll, or any sensation of loss of control. As the car senses that you are in an aggressive driving mode the suspension should tighten further until the road and steering feedback is pretty intense. If you really get carried away, the transmission will enter PAS (Performance Algorithm Shifting) mode in which you are, in effect, driving a foot-shifted manual transmission. If you're willing to experiment, the F55 cars are capable of maneuvering and handling that the F45 series can only dream about.
