I have replaced an arm, tie rods, stabilizer bar, had an alignment, new tires, sway bar, and bushings. Still shaking more than before.

Just thought I'd mention that I did have some vibration in steering a couple years ago and needed tie rod ends replaced. Fairly easily resolved issue. I have not had any serious issue with this car to speak of since I bought it in 07. Served me well. High miles will take toll now probably.

Vehicle vibrates mainly at slower speeds or when you accelerate. Replaced drive axles and now am told it needs tune up and could possibly be transmission. Other people I know who have had a car like this or knew of someone who did said they all had the same problem and couldn't find a fix for it. Is it a factory flaw or was this just a bad year for the bonneville?
