This is my first post and I hope I can find someone with great knowledge on vibration correction for Volvo's.


What I have done is replaced the u-joints, carrier bearing, and center support. I replaced the trailing arm bushings, ball joints, tie rod ends, sway bar end links, strut cartridges, and shocks. I installed the A/C compressor bypass kit from IPD due to a failed bearing in the compressor. Brake pads, rotors, and tires are all new. Transmission mount is new and motor mounts as well as exhaust hangers are in good condition.


I am having trouble identifying the source or sources of vibration because it seems that it is noticeable while under load and not under load. I believe I have 2 vibrations because they are present under load either by acceleration or downshifting. Manual 4 speed w/electronic OD. I also can coast down through a vibration with no load on the motor. I have even stopped the engine while coasting and it is still present. The speed is around 50-55 mph for a coast down no load vibration. The under load vibration is always present.


What are the most common sources of vibrations on these cars as a starting point? Do the B21F engines have an inherent vibration that is normal?
I have access to an EVA2 "electronic vibration analysis" tool where I work and have used it to try and diagnose the vibration. One comes in the hertz range of a second order engine vibration and the other is in a hertz range that does not match anything and is displayed as unkown vibration.


I apologize for such a long post but I want you to be as informed as to what I have done so you may help me do what I have not thought of.
