Alright you guys I haven't seen or felt any type of wear yet in that drive line and the car drives smoother than ever. I will continue to update if I see or feel any changes. Since my truck is lowered pretty much as low as it can without sitting on the bump stops. the straight shaft doesn't touch on anything and looks to have the perfect angle. Thank you everyone for the suggestions and things to look out for. I will keep everyone updated asap...
