okay thanks

just got some new bushings today, the ones for swaybar-to-frame and swaybar-to-a-arm. hopefully that will cure some of the problem
just in case someone is looking for part numbers or torque specifications:
swaybar-to-frame bushing (70-90 Nm): 1630507
swaybar-to-a-arm bushing:
outer disc 1656752
inner retainer disc 6172539
inner pressure disc 6172540
nut (nylon-secured) 6523434 (tighten to 70 to 110 Nm)
I'll post again after installing them and a rainy test drive
btw - this forum has no driving smileys??
