Hi everyone,
I have a 2000 Pontiac Grand Prix GT with a strange vibration issue. There is a vibration when accelerating and it occurs around 40 to 45 mph and then goes away. If I am coasting at those speeds there is no vibration. I have replaced the tires and balanced them and had an alignment done. I then even rotated the tires to see if it was a wheel balance issue. The shop did do a visual check of the CV joints and said they looked fine when they did the alignment. Please help me figure this out so I am not throwing parts at it.
Thanks!
