So I've been dealing with this problem for about a month now and its getting really aggravating. A while back i noticed my cv boots were both torn so I decided to get my axles replaced. After taking it to a shop and getting them replaced the car started to shake at about 20 mph and went away after 30mph, but then again after 60mph +. So i figured they were bad axles and took them back to the shop to have them replaced again. So the shop "supposedly" changed the axles again, but when I got the car back, it was the same problem. So third time i bring it back and demand they replace them again because it has to be the axles. So third times a charm right, wrong! They even said they took it to an acura dealer down the street and the dealer said it shakes due to it being lowered. BTW i am on tein basics for suspension mods, nothing else. I had the car inspected for balanced wheels, bought new tires, and even had someone check out all other suspension components with nothing wrong. Now can someone please give me some insight, because if the car wasnt shaking prior to bringing into that shop and now it does wouldnt it have to be axles.
