I have this same car with exactly the same problem. Begins shaking at 40mph and stops shaking as soon as you let off the gas, but then begins again as soon as you press on the gas and smooths out as you get over 50. And the shaking is not felt through the steering wheel. Solution: Replace the transmission mounts. There are two of them, one on each side mounted on the frame right next to the shock strut. There is also a front and rear engine mount, but I replaced the two as described and shaking is gone.

Hey Eddie..my name is Keith....and usually a bad vibration between 30 and 55 MPH indicates that one of your tires is out of balance..and if the steering wheel doesnt shake..that leads to think a rear tire is out of balance..but this is the easiest thing to have checked at a shop..but there could be other things..so lets pray that its just a tire out of balance...if it isnt..write me back

On 98 caravan 2.4 it starts to wobble at 40up to 50 mph mostly when accelerating when speed reached smoths also smooths out after 50 mph alll new including valves. could bad wires cause this?


How old are the good tires? These speeds usually mean belt or balance problem with tires...If new tires, they need to be re-checked for balance...and not out of round...also check for bent wheel...due to chuckhole? Sometimes a bent steel wheel can be hammered straight...hope this helps.

I have a 2005 Toyota Solara SLE. I having problems with the front end. The car shakes/shimmies upon accelaration at approx. 40 mph. It smoothes out if you take your foot aff the accelarator but shakes...


Check the condition of your tires and suspension. this problem is usually caused by bad component or alignment. Special attention is given to camber and caster.

My 1989 Chevey Celebrity started shaking the other day the front part of the car, not like the front end is messed up but it shakes.


Could be a wheel, tire, or axle shaft.
You could rotate the tires front to back and see if the vibration moves.
If it does the problem is one of the tires or wheels.
If it stays in the front, its probably one of the axle shafts. It could also be a hub bearing or something loose in the suspension. But a loose suspension part would normally show up when you hit a bump rather than on a smooth road.

When i use the brakes over 50 mph the front shakes. between 40 and 50 mph theres a little shaking, below 40mph its brakes smooths


A slight shimmy under braking is usually the result of a brake rotor that is not true. Sounds like you may have a warpped brake rotor...I would check that, and your front suspension componets for wear.... I hope this helps.
