My 2006 honda ridgeline has alot of vibration coming from the front end this is not a constant problem. It does it mostly on the irregularity on the road. My mechanic advisor told me to change the front sway bars bushings but there is still the same vibration and noise like a "klunk" beneath-center of the lower body. Any suggestions? Thanks!
Without understanding the type of vibrations you are refering to, it is not possible to provide a precise suggestion. If the vibration is coupled with noise, that would mean a worn bush or link somewhere.
Apart from the sway bar bushes, were the links checked or replaced?
