Hi Breanne,
Welcome to the forum. Wish I had met you back when I got my first Aveo. It seems the bearings in the rear wheels of the aveo were cheap and/or poorly designed. My car had this issue(wheel vibration) at about 4k when I brought it in the dealer told me it was a bent rim and wasn't covered .So I bought $600 aftermarket wheels and still had the problem. Went back to the dealer later I don't remember the mileage but was told this time it was my alignment. paid $75 or so for the alignment and you guessed it no change. Went back to dealer again and was told it would require a special alignment (never heard that one before) so Isaid ok. and no that didn't fix it either. I just kept driving the car it wasn't a horrible vibration so I just lived with it. Fast forward to 30 some thousand miles, now the vibration has turned to a shake. My wife took it for a ride and said to me you've got a bad wheel bearing. So tell me how can a dealership not know whats wrong with the car and my wife can drive it once and tell me whats wrong????(besides the fact shes an awesome mechanic)This is why we never take our cars to dealers any more. So I went in to the dealership and told them what was wrong and how they had "overlooked" the real problem. I was then told that they couldn't help me the warranty had expired and I had no prior documentation of the problem. WOW can you believe that I couldn't. Anyway I changed the bearing (here's a note to anyone that has to do this: It takes judicial application of heat and at least a 30 ton shop press, heat it or cool wrong and you'll warp it! These drums go for around 2 to 3 hundred dollars. not a job for someone who hasn't used a torch alot) out of pocket in my shop for about $60 but it was a nightmare even getting the part back then, I don't know how it is today. So you will have to understand my skepticism when it comes to GM "outreach" Well Breanna now that Ive' gotten that off my chest I'd like you to know I still love GM cars. I've got a 67 stingray,a 96 Camaro SS with the SLP package,a 93 S10 tahoe 4x4, an 89 firebird and a 92 firebird convertible and I just sold my 69 400 four speed firebird. I love the new vettes and if this economy ever picks up again I'm gonna get me a new one!!! I think I took enough of you time up now so I'll see you in the forum!! P.S. Please don't take this personally it certainly isn't meant to be an attack on you I'm glad your here...
