the centre bearing is failing on my hilux too quick, I have a judder in the driveline on take off but it goes away at road speed.

What I found was when I swapped the driveshaft with my parents the problem moved (and I had to swap it back), when I swaped it back the two shaft's were 90 deg out (one was turned 90 deg) I changed this and the problem went for a bit but now it is back.
