I just read the thread from abolfaz. He broke down on a back road in his new GT, and the half shaft bolts were to blame. The problem seems to be common on late 05 and early 06 cars. My question is do I have the upgrade before I drive the car, or do I risk getting stuck somewhere. My car is an 05 with a vin#1946 which would make it a late 05 car. I just had the car delivered and I am waiting for the salt to be washed off of the roads in about a month. Should I have a mechanic look at the car, and can he tell if the car has the problem? The car has 12 miles on it.
