I was very surprised the first time I looked under my truck and noticed a two piece drive shaft under My 2003 GMC 2500 HD two wheel drive. I have noticed other people indicate in there truck descriptions that they have a one piece drive shaft. I'm guessing this refrences the fact that they changed what their truck came with.
I did a topic search to no avail. Would someone please share their knowledge on why this was done. what aftermarket products were used, the benefits, the effect on the warrenty and the cost of this modification. Thanks
