Hi
I've just finished replacing the chassis on my series 3 SWB I've also fitted parabolic springs. It now has a bad vibration that didn't used to be there before I changed the chassis and springs.
The vibration only occurs at around 30 - 40 mph and 65 - 70 mph, it is worse when accelerating and decelerating through these speeds.
I originally thought it was the prop shaft as it was worn and rattling all over the place so I fitted a new shaft, but it made no difference.
The only difference I can see from before I changed the chassis and springs is the springs have lifted it a good couple of inches, can this make a difference?
Anyone got any ideas on what it may be?
Thanks
Liam
