Having the suspension springs break is not an unheard of problem among mechanics, but having these springs break after just a few thousand km’s is… after doing a bit of research on the net about lowering-kits with problems, most of these springs last about 80-90’000 km at best, its not something that is in particular linked to just Saab but seems to be a fairly reoccurring problem.
One lowering kit a good friend of mine recently found out to be a problem with in his car was the one made by H&R and sold by Speedparts. It was installed in the car, a 1999 Saab 9-5 Sedan in 2006 and has been driven only a few thousand km when sounds from the rear suspension started to appear. The springs were broken, not just one but both rear springs in 3 different places. The car has been driven almost exclusively in city environment.
What I also find interesting is that the protective color is almost completely gone. Comparing these with several original used springs with almost twice the amount of km’s from the same region and same age shows that their color is still in place.
No real conclusions can be drawn from this one time incident but searching the forums on the net a bit does show that there are a problem with broken springs with some lowering kits. What the cause is, is still unknown… What is your experience?
