alright solved the problem i hope. i took the rear driveline out and put the front one in and drove with front wheel drive. no noise. i brought the rear driveline to my buddies shop, and he says, the splines were worn out, and its the worst splicer u-joint he has ever seen. guess it was worn out pretty bad. so he is gonna cut the splines off and weld a toyota spline from another driveline i have. hopefully it solves the problem. i'll give u guys an update.
thanks for the help
