Greetings. I am growing very frustrated with the constant shake in my 2002 Passat wagon. A couple of years ago my wife had a blow out and I ended up replacing all 4 tires since it was time. I went with Michelin Primacy MXV4 (which I think the suck anyway). They have about 27000 miles. I have had the tires rotated about 3 times and the balancing always seems to go out. I purchased the tires at our local Discount tire and I have had to Road force balance them yet again. I do have a special warranty that should replace them in case one or more of them are defective. Before the last rotation the tires were fine I also had the rims inspected and they seem to be fine. I feel the shake mostly in the seat and the steering wheel does not suffer from usual side to side vibration
Another very curious thing is that they tend to shake a little bit more when I am going up hill. We live in NC and the highways are a bit hilly depending where you live. It happens in the 65 to 75 MPH range.
Everything else in the front end and suspension components seems to be fine. Any help is appreciated. Thanks in advance
