Hey guys, semi-proud owner of a 2004 R with the "venerable" AW55 here. I have used various search features and the responses seem all over the place regarding the following questions so i figured i'd bring them up to see mainly if there is any more definitive information available as of now. Facebook groups seem to be of very little help.
First: I am sick of the "crashing" over bumps. I've replaced the upper shock mounts, sway bar links, bushings, subframe bushings, based on available information, this seems to be a normal issue. I am sick of it. I've tried moving the accelerometers for the front shocks to the chassis and that helped only slightly. I can still tell a significant difference in overall handling when changing between the three settings on the dash, but otherwise I expect the only improvement I'll ever find is with new front struts at 350-450 each plus a trip to the dealer for SUM calibration. Currently the car sits on mild Eibach springs and is properly aligned. This information seem correct? Am I missing anything?
Second: I've seen mention of this problem being somewhat well-known. Driving over bumps, a problem in the rear that presents itself as "crab-walking", for lack of a better term, rears its head. Its rather annoying and doesnt inspire confidence in taking curves at any moderate rate of speed. This is disappointing as i've installed some really nice tires as well as IPD's rear sway bar and would like to take advantage of those upgrades. Those of you that have experienced this, what was your solution? Is it a sign that the REAR shocks are worn out as well? (Another 350-450) Or is this another "quirk of the S60R". Im hoping its the former and not the latter. I cannot imagine volvo would design a car with such horrible handling characteristics.
If the general consensus is that all 4 shocks are in need of replacement (none are leaking, and there is still a noticeable difference between the three suspension settings), I've also read that these things are usually only good for 2 years or so.... Is that normal? 2 years? I mean I guess in two years another 1200 wont be a bad idea, and I'd like to keep the suspension adjustment functional, but a set of BC coilovers is only a grand although I'd upgrade to Swift springs and choose different rates also, they would likely last alot longer than 2 years (maybe?).
