Shakes or Wobbles problem
2003 Dodge Caravan 6 cyl Front Wheel Drive Automatic 117000 miles
Started about 2 months ago, feel a vibration in the front seats and can see movement in the rear seats between 80 and 110 kph.
Vehicle was modified about 3 years + ago for wheelchair access with a rear entry ramp. We have NEVER had a problem before with vibration until a couple months ago.
So far we have started by balancing the rear tires and cleaning/inspecting the rear brakes. Next we had all 4 tires balanced and inspecting/testing of rear suspension. After that we replaced the 2 rear tires with our winters and inspected the rims for dents or any warping, as well as another inspection of the rear suspension. By this time u can imagine my frustration. Next we decided on a highspeed balance however due to our summer tires being almost out of tread we purchased for new all seasons and high speed balanced those.
Today we took a trip which distance totaled around 600k. Any time I was between 90-110kph there was a lot of vibration, specifically at 100kph was the worst. If I drove at or above 120kph it seemed the vibration was minimal or non existent.
I am stumped. Could the wheel bearings be the problem? I am very hesitant to blame the modification as it hasn't been a problem in the past.
Any suggestions would be very much appreciated.
have the same problem?
