There does not appear to be any difference in the sound if I am going straight, to the right, or to the left. can a bad carrier bearing cause a whining noise only during deceleration from 70? Just for review the noise is consistent when coasting and does not get worse if the car is put in neutral and revved. Thus there is nothing replenishing the power lost through friction. My '97 Buell (1200), 17k miles, just started making a similar tranny noise. I believe it is coming from somewhere in the engine and it happens when i step on the gas. Cant tell if it is coming from engine or tranny. Basically when I accelerate there is a loud whining noise when the RPM's climb up and it follows deceleration as well. The power steering pump would carry low level of fluid or be faulty. Its always made that noise since I bought the car with 40k and has now done 80k without the turbo going pop (yet). The sound is like the whine that occurs in the last few feet of deceleration when the AOD downshiftsthat little whine as the lower gear engages. "Clunk" sound when accelerating and decelerating - What is it?. The Subaru dealership here told me a $1500 clutch replacement would probably fix the issue?!?!. I droped my car off at ford this morning for the recall job, and they recon that it is not common at all and that there is no additive that they have or can put int. It's coming from under the hood so I know its not the wheel bearings on my car since I've had them replaced about 2000 miles ago. It is a CVT, definately not a grinding noise. When ur on the gas the momentum of the drivetrain changes and outs torque on diff bearing. Is it noisy accelerating or decelerating? Braking or crusing? On idle, when you change gear, when you depress the clutch or turn the steering wheel? This can narrow it down to the vehicle system involved. Drive shaft noises are usually caused by worn U- joints, slip joint wear, or a faulty center support bearing. Days after changing the oil on my truck a very loud whining noise started to come from my engine. Cars can make these whining noises from 1 of 2 places. Last week, on an 800-mile road trip, I noticed a new whine coming from the rear end, only present when decelerating without using the brakes. ernie1 Junior Member. Makes a whining noise when Im accelerating and decelerating but only when Im doing the speed25 and under i replaced shift solenoids It definitely sounds like its coming from my transWhat could it be The power steering pump is the only thing that really causes this problem.
