If it was a gear cluster bearing, it would whine in 1st, 2nd, 3rd and fifth, but not fourth. What model, what year,what engine?
A lot of Patrol gearboxes require a GL4 oil instead of a GL5.

Some early GU's are renowned for a weak 5th gear. I don't know what year range this belongs to. I think there was a upgrade released.
Just search for GU 5th gear on this forum. Or google it.

Those manual gearboxes are strong as Even the pre 2002 with shorter splines for 5th.
Check elsewhere. Personally i dont think its the box. Check diff fluids and transfer case too
