To start with what I did before this problem happened I'll explain the story.
Day before the heavy vibration:
I drove 2 hours out and drug home a CB with the RA. Van was fine, no problems.
Day of the heavy vibration:
This morning, drove to work back and forth between the buildings I work at, no problems, van was normal besides saw that coolant was leaking from the heater core hose.
Before I went home I drove to my mother business and had a snack then got in the van decided to have a little fun and slid around a little in the parking lot while the asphalt was wet. (may be the cause?)
When I started to get on the highway I noticed the heavy consistent vibration (with revs/RPMs) all the way home. (note this didn't happen in the morning)
After I got home I pulled the van in the garage to replace the heater core hose, fix my oil leak from the dizzy and put new brake pads on. (none of this would affect the problem above, or shouldn't)
My cousin noticed in the rear right strut, one of the nuts was gone on top inside the van, and the strut was starting to come loose. Put a new nut on tightened them down. (may be the cause?)
Then a few hours later hopped in the van to take my girl home to get her clothes and such, the vibration is no longer consistent but now is pulsating in and out like a sine wave. It's like a perfect sine wave, not inconsistent. (very very annoying rather have the consistent vibration)
When I got home, I checked timing marks and the balance shafts are in time. I loosened all the motor mounts (ESP Mounts) and re-tightened them down, even gave the exhaust a few kicks to see maybe if it was up against something causing the vibration. Took it for a test drive, problem still exists.
This vibration problem happens all the time, the van is in neutral at a stop. The higher the throttle is held, the quicker the vibration sine happens. It's not CV shafts, or suspension because the car is not moving. So could it be motor mounts just shifted around or settling in, or is it possible for balancing to go bad in the motor?
I couldn't find anything related to what I have on google, all I found is your motor mounts are bad, or balance shafts aren't set correctly, but both are good. New mounts, timing hasn't changed. I'm at a loss, any suggestions?
