: I keep experiencing a vibration in my car while accelerating in 2nd gear from 2-3K or so. I was able to reduce the vibration by replacing the rubber u-joint (guibo) but it hasn't completely gone away. There doesn't seem to be any vibration during steady cruising at any RPM.
: This is a 535iM, but it turned out that the rear subframe bushings were allowing the entire rear subframe to jump at least an inch vertically..These are a bitch to replace without heat and special tools, but it will fix the cconcern..Also look at the rear pitman arms..About $100 ea, but they also tighten things up a bit.
