HI.
I have a Grand Caravan SE with a - 3.3 - 4 speed auto - 58,000 Kilomters.
A few weeks ago I notice a bit of a sideways shake as I would accelerate through 50 to 65 km. This shake was not noticable at higher or lower speeds. The shake would disappear as I backed of the gas. When driving the car and as the shake starts I can feel it through the floor pannels in the drive side. Note, the road has to be fairly smooth to notice the shake as opposed to rough, uneven roads.
I recently put 700k miles on at highway speeds and did not notice any problems. Steering was fine, did not notice any real shakes but Saskatchewan highways are not that great anymore :-).
Recent contact with a garage thought the problem would be related to Cv shaft and stated that generally speaking, they would normally start with the left side/driver side (shorter,more angle to it) and see if it fixes the problem. When he took everything apart he stated that the shaft had some play in it and was pretty sure that that would solve the problem. It did not. The replacement part was a re-engineered NAPA part not factory replacement.
I spent some more time with the technician road testing it and he did not have any other ideas; except replace other shaft and see if that helps.
Before, spending any more money replacing the other CV shaft I plan on getting another opionion from another garage but thought I would post in case anyone has had any similar problems or any advise.
