Well about two weeks ago a friend of mine noticed a clunking coming from the rear when going from reverese to 1st set up a apponment for oct 12th for the dealer. Well today while leaving my road I found out what it was seems they did not tighten the half shaft bolts. I went to shift from 1st to 2nd at about 4500 rpm to 5000 rpm not to hard of a shift but a descent one and traction control was on and it sounded like I mised 2nd pushed clutch in and let back out and nothing I was like wtf?! heard a clunking noised coming from the back so I coast into the gas station as I hear parts falling out onto the parking lot. I pick up all the pieces 4 bolts 2 hold down pieces and the cover that holds the grease in. So now im stuck with a pontiac vibe (which I hate sorry to any vibe owners) for a rental!!! when I bought this car and from what I have read in the fourms that this is a tsb and a know problem and the dealer had taken care of all of these! Im very angrey at the moment *Sigh* Here are some pictures I will upload a video to my webserver later had to take pictures and video with my phone. As you can see the bolts are fine not twisted and no thread damage just *fell out* Im just glad this did not fall off when i was going faster imagine that halfshaft smacking the underside of the car doing 70! this needs to be brought to pontiacs attiton that this is a serious problem and recall the vehicals as this has to be a safety concern as well! who else here has this happned I know i was seeing posts just last night about These cars doing this but around 700 - 900 miles mine has exatley 5,550 miles..... !
