1991 Plymouth Acclaim Vibration

I have a annoying problem with this vehicle. When I stop the car (i.e,
at a stoplight) the entire car vibrates. This vibration stops once I
remove my foot from the brake pedal. If I gently touch the brake it may
not happen. The vibration only occurs in forward gears not in reverse.
Also, if I place the car into Neutral the vibration will go away. Could
you please tell me what could be. I have already replaced the front
brakes and a bad CV axle thinking that this would fix the problem and
it didn't. Please help....

 

Check your motor mounts???

 

I had a 1994 Acclaim which made a nasty vibration sound - just like
you describe. Put the car in "N" and noise went away!

In that year there was some sort of heat shield above the exhaust and
below the fire wall? In any case, it seems that there were only 2
bolts holding it in, and one of them had fallen out!

I was thinking this was going to cost me a fortune, and it wound up
cost almost nothing!

And if your problem is the same as mine was, and your shop did all
that work without finding it, then it is time for a new shop! My shop
found it in about 5 minutes.
