Hi Car Talk Community,
I have a 2006 PT Cruiser with approximately 94K miles on it. This year I started a 2-hr round trip commute every week day, so the car went from getting ~200 mi. a week on it to ~700 mi. a week. I bought it used ~4 years ago with 28K mi. on it.
2 months ago, the car started shaking between the speeds of 50 and 60 mph. Not sure how to best describe it - kind of a shake/jerk, like someone was jerking the car forward very quickly and repeatedly. It seemed to be strongest in the front of the car on the passenger side, although you could feel it throughout the car. I took it to a repair shop. They balanced the tires, but that only very mildly helped. Then they changed the front axles (said there was a lot of play in them). They replaced the brakes, rotors, and timing belt at as well, for unrelated reasons. With new front axles, the shake disappeared, but the car has been idling incredibly rough ever since I got it back. You can see the steering wheel vibrate and feel it in the seat when I start the car or am stopped with it running. This never used to happen.
Additionally, the shake has now returned, but from the driver’s side of the front of the car now. Again, it’s between 50 and 60 mph, although it’s slowly creeping up into the 60-65 range also. It’s stronger if I’m pushing the gas down more, like when going up a steep hill. If I’m going downhill at 50-60mph, I don’t notice it or barely notice it. On flat ground it’s noticeable, uphill it’s becoming severe.
Any ideas on what could be wrong? The repair shop I go to is excellent and treats me well, but they had trouble figuring this one out. If I can go back with some suggestions I’d feel much more comfortable.
Thank you very much for any help/suggestions! Please let me know if more info would be helpful.
