'99 with 173,500 miles needs the complete front/rear spring, strut/shock upgrade. The forum suggests 2 options as a nice direct fit "bolt on" upgrade. First being from the 06-07 BUICK LUCERNE (V8 MODEL PREFERRED). Second from the 06-07 CADDY DTS. Are the suspension parts different between these two model cars, or do both cars share the same components? If they are different what are the differences? Is one better than the other? Thanks ! This forum is great.
Thanks for responding.. Had you (has anyone?) tried the firm ride front struts for the 07 lucerne ? Presently the car handles like a vessel ..LOL .. navigating the open road rather than driving down the roadway. .. I wouldn't like to over compensate and install a firm ride strut when likely I'd be satisfied with restored OE drivability. I am doing the end links and sway bar bushings and a strut tower brace as It's reported this makes a considerable difference.
I doubt you'd be dissapointed with the "F41" suspension, You know it had to go through a ton of testing before it was offered on a car, however, based on your mileage and the "loosy-goosy" worn suspension that comes with time and many miles, I would guess you'd be very happy with just updating to new versions of the OE equipment.
Yes I wish to upgrade! The suspension is original except for OE air shocks installed 50,000 miles ago. I am limited to options that fit directly and bolt on. I intend to replace all related parts top to bottom, front and rear, ie.. mounts, coils, spring seats, etc. This poses the question, if not new OE components listed for the 99 or those for the 06-07 Buick Lucerne (v8) what else would fit directly and bolt on with no modification.? I have seen the sticky for the classic parts swap, also the "brain" had confirmed 06-07 lucerne suspension parts would be a direct fit and bolt right in . However, this information might be dated.
