The diagnosis sounds OK but if you have no experience with auto repair, I recommend you invest in an after-market service book for your car.
Haynes has it on line for $25 but you should be able to buy it locally from any chain auto parts store.
You can see it here:

It will pay for itself many times over and even if you don't DIY, it can help you determine if the repair shop is asking a reasonable price for a repair.

I have a nissan maxima 04 and when I switch my carr into drive it jerks one time making a big thump sound ..some one told me it might be the motor mounts would this be true


possible but more likely issue with valve body in trans.is it a 5 speed auto?does it get worse the hotter the trans gets?the mounts are a common failure on these but generally when they fail you get a big thump when you initially hit this gas when pulling away from being stopped.

What causesa car to jump when gas pedal is pressed


A bad throttle position sensor is the most likely cause. They work just like a volume knob on a radio. If you ever had a radio that would play static in spots when you adjusted the volume, it was because the switch was jumping over the bad spots. Your cars throttle may be doing the same. On your car this sensor should be above the pedal, and will need replaced, they are not fixable. About a $100 fix at most shops.

The problem is the rear motor mount is filled with hydraulic fluid that leaks onto the accessory drive belt. The motor mounts fail prematurely and the fluid makes the belt squeak. Toyota dealership I took my 2006 Corolla to replaced the motor mount and belt free of charge.

When iput my car in gear i can fell the motor raise up with a thump noise also fan belt makes a winning sound


The Motor raising up issue is, you may have a worn or broken Engine or Transmission Mount, inspect the mounts by having someone or you, look at the mounts while someone else puts the car in gear. If you see the mounts move excessively, than the mounts need to be replaced. The whining or squealing Fan Belt may be a worn, glazed or loose belt. I would inspect the belt and tighten or replace as needed.

When i press the gas it make a loud thumping noise. everytime i take off and press the gas it make this noise and it sounds like something is hitting somethin but its not.


Sounds like the engine mounts are worn or damaged and needs to be replaced. Inspect the engine mounts and replace as needed, you can inspect the engine mount by having the hood up with the engine running.
Have someone put the transmission in forward and then revers to see how much the engine is torquing in the engine bay, if it's moving to much. Replace the engine mounts.
Thank you for using fixya and be safe.

I have 2 problems. First the front end of my 2005 Grand Caravan makes a thumping noise. I thought it may be the struts or stabilizer bushings, I took it to a dealer and they said that it is niether and...


As for the front noise. Sounds like the ball joints. They wear a groove in the cup, where they sit. When they go over the lip, they make a thump sound. As for the rear wiper arm. If the arm has been taking off, folks strip the knurl teeth out of the arm. If the motor is working back & forth right, & wiper arm is tight. Oil the hinge pin on the wiper arm. They get alot of dirt on the back window. If all else fails replace wiper arm.
