99 Caravan Vibration

The first thing I would do is rotate the front tires to the rear, and the rears up to the front. If the tire belts are getting bad it can sometimes cause the steering to shimmy at low speeds. Rotating doesn't cost anything if you do it yourself, and is a quick way to eliminate the tires being the cause. We had the same problem on our 99 Grand Voyager recently and a new set of tires up front solved it.

You originally said it happens at "low speed" which I interpreted as being in first gear. If it happens at higher speeds (3rd gear) it's not as likely to be bad belts in the tires. Maybe bad CV joints, bad mounts, etc.

Finding the TSB index for free is fairly easy. Getting a detailed summary usually requires a subscription:

My 94 vibrates bad about 41 MPH only on acceleration.

Replaced both front tires and had new ones balaced, new front wheel bearings and hubs, new front brakes and rotors, all 3 engine tranny mounts replaced, rebuilt 1/2 shafts with CV joints.

Shimmy is still there perhaps getting a bit worse, if anyone has any ideas I am all ears.

Short on cash I talked to a local tranny shop they will look at it but sound as mystified as I am. 94 caravan with 3.0 about 100K miles

Its getting worse once ot breaks I will know what it is, but DONT want event to cause accident
