The car is a 1987 with dealer control arms replaced in August to cure a HARSH intermittant vibration that was more like a thumping. I keep hearing about driveshafts - what all was done to yours? MY center support bearing and support are original but at last check were "okay" - not torn and bearing not making noise to mechanics stethescope. Maybe I should change them anyway?
Can I conclude that the steering gear or steering coupling would not aggrevate vibrations in the system?
