Is the noise under acceleration or when taking off from a stop?
When you say the car jumps, do you mean it surges forward as if you pressed the gas?
Does it feel like the car is actually jumping around?
Do the 2 things ever happen at the same time?
Try this forst and if it is not the problem, get back to me with some ore details and I wil try to help.
Open the hod of the car and get in with the car running. Place the car in drive and put one foot on the brake and while you are watching the motor itself, press the gas while still holding the brake with your other foot. You don't need to do this long, just a quick blip of the throttle.
If the motor moves excessively or makes the noises and types of jumping that you have been experiencing, then the motor mounts are in need of replacement.
Be sure to replace all of them at the same time.
This is because when one mount fails, the others take the load of the faild mount and quickly fail too.
If you replace the on mount and the others are near failure, then they will fail and cause the replaced motor mount to fail.
Let me know how it goes.
Please consider a to help us answer more questions.
