Question about Pontiac Grand Am

My 1997 pontiac grand am makes thumping noise when accelerating and turning in either direction. Does not make the noise when moving in reverse. Have checked the CV Joints and they are good. Replaced brakes. Even leveled motor. What could this problem be?

    On 96 Grand Am 2.4L you have to remove the right side motor mount first to get the top 2 trans axle bolts on the left side trans axle mount bracket removed. You will need a 3 foot pry bar to move the engine over to the side as far as possible to make room for the 2 top bolts to be removed. The trans axle bracket and trans mount are removed as one unit after all 8 bolts are removed.

My 2007 pontiac G6 has a thumping noise in the dash somewhere.Cant seem to pin point it


Need more information. Is the noise while you are parked, driving straight, turning left or right, reverse? Are you accelerating, coasting, or braking? Is the A/C or heat blower on?

What is the cause of continual thumping (appears to be coming from back of car) and violently shaking?


Many times, rear tires that are out of round or severely cupped or feathered, or that are out of balance can create this type of issue. My first recommendation would be to have them and the wheels on the rear of the car inspected. There may not seem like there is much wrong visibly if you look at just the tread of the tires, but a good tire tech can spin them up and give you some solutions, and the inspection itself is inexpensive. Hope this helps.

Sounds like your transmission is slipping or your torque converter is bad.---check the transmission fluid level and see if it smells burnt and discolored.

It sounds like a belt thats slipping. You have a sticking puley somewhere, take off the belt and rotate all of the pulleys. Usually its an AC compressor pulley so pay special attention to it. The whining noise that it makes while turning, is it the same as the squealing noise? If so it could be a problem with the pump, check the fluid level and see if its an odd color or has an odd odor (like burnt or black). Hope this helps!

My car makes a thump-thump-thump sound while i am driving it


sounds like a tire may have a flat spot on it, causeing it to make a thump noise. the main cause for this is bad shocks or struts on that side.
