Shaking From The Rear

[xchanger]

My car is shaking from the rear. Anyone had that kind of experience? Please let me know.

When does it shake? is it a constant thing, does it change with speed? Have you checked the wheels out, it might be a wheel balance issue or it might be something else, any more information you can give might be helpful.

The car shakes from the rear at around 55 mph. You are absolutely right. It could be the wheels, but are there other common possibilities?

any difference if you were to let off of the gas, maybe put the car in neutral also?

[Nick_318is]

if it is happening at 55 and above my best bet is something is out of balance. A quick no cost check, you could take the wheel(s) off and look and see if you can see anyplace where it has thrown a wheel weight and if you see something like that then you know its a wheel balance issue and a quick, cheap fix.

There are rubber mounting supports (commonly called beer cans) on the rear axle carrier and if they deteriorate she will shake.

I have taken my car several times to the dealership complaining of this issue. They told me that their mechanic could not duplicate this. It has been 2 years and now the car is out of warranty. The mechanic now can duplicate the issue and they tell me this is a know anomaly. If is random at low and high speeds. Usually in a situation when the car is unbalanced and over compensates or exaggerates the shaking. It might have something to do with the auto leveling. It seems to be presenting itself more frequently and always over speed bumps and parking lots. Does this sound like the same situation?

easy check... have your tires balanced (and i must specify, DYNAMICALLY BALANCED) not static balance.

Then, rotate your tires.

Having done that, and you still have the shaking problems. the prob is in the hub and/or suspension system.

* you differentiate shaking also while braking.... shaking or vibration on braking is warped rotors and/or poor quality pads

another remote possbility is a Doughnut type bearing on the (Prop) shaft under a metal cowling depending on age f vehicle it could be a rubber mounting bearing under same cover between gearbox and axle.
