Ok guys and gals I am still working on the noise issue
But some findings are as follows
I have re shimmed front and rear diffs so there is no play in side to side movement in the diff casing and spins 100% true to the pinion mesh so there is just the right amount of backlash. One thing I did notice is after a little period of time make note and check that the out drive you attach to the diff pinons to the centre driveshafts are set all the way against the shim and bearing that's mounted in the diff housing.
Number two is I am waiting on my new main or spur gear as some call it as that's the last thing that's not new. I also moved the engine back to the forward mount position thinking it shouldn't make any difference in noise and to be honest I think it's just a thing in my head saying it's a little quieter but I would say not. So all in all right now spur gear is coming but with everything else all gone over there will be no excuse when the new spur gear is on.

Thanks for the help and I hope all the little things I shared reminds others of the things I have gone thru to get a new smooth drivetrain
Cheers
