what sort of a noise?

I can safely say that the noise will probably be due to the drive shaft geometry after you put the 4" lift in.
Either invest in some longer rear lower control arms in (10-16mm), gearbox crossmember packers, adjustable upper rear arms or a double cardan rear shaft should fix the problem.
Search is your friend.

I have the same problem now!
I just did 4 inch lift in a SWB with longer lowers and a double cardinal, the virations were bloody bad as I couldn't rotate my pinion high enough.
My stock drive shaft went in and zero vibrations now, but when I back off the accelerator or push the clutch in I get wierd noise coming from the rear end, it sounds simular to bearing noise but it isn't.
Waandy did you find out what was casing this noise? Anyone else come across this before?
I have 15mm gear box spacers, 14mm longer lower arms, adjustable uppers.

Sounds like it could be a Uni joint, my HiLux did the same thing. Check the one closest to your diff.

Cheers will do, if that doesn't work will try a harmonic balancer for the tail shaft next.

Just searched through 50 pages of threads back to 2003 and found that this noise in most cases is coming from the extended spline! due to lifting suspension. Some solutions were to pack it full of high quality high temp grease once a month, unbolting and rotating the driveline 180* helped one member. I am guessing a tailshaft spacer would be solution also.

def due to spline etension. lots of regular greasing will cover up the problem not fix it. dont do tailshaft spacer as this will only make ur uni angle worse not fix the prob. longer lower arms and double cardens dont mix.only use longer lowers with standard shaft

Have you tried a tailshaft spacer? I haven't fitted tailsafter spacer, I can see how your uni angles would a little but the spline wouldn't be extended anymore and back to stock so the problem should be gone. Snake racing sell 15,25 and 40mm tailsaft spacers.
The other option would be to get longer drive shaft.

Has anyone tried a new longer tail shaft?
